Some Bumps in the Separation of Entity Framework and .NET Framework

It's almost like a feuding spouse who leaves the partner only to find out how much they're missed and decides not to cut ties completely and maybe hang out with each other now and then. Well, almost.

The Entity Framework team disassociated itself from the .NET Framework release schedule after EF 4.0 was released with .NET 4.0. The first manifestation of that new policy came last spring when the EF team released an update, EF 4.1, with developer-requested improvements such as Code First capability and a DbContext API.

"This is the first time we've released part of the Entity Framework as a stand-alone release and we're excited about the ability to get new features into your hands faster than waiting for the next full .NET Framework release," said a posting on the ADO.NET team blog announcing EF 4.1. That was followed up in August with the release of the EF 4.2 Beta 1 preview.

But today comes news that the trial separation didn't work so well and some new EF features--including much-wanted enum support--will have to wait for a full .NET Framework upgrade.

"Our new features that require updates to our core libraries will need to wait for the next .NET Framework release. This includes support for Enum Types, Spatial Types, Table-Valued Functions, Stored Procedures with Multiple Results and Auto-Compiled LINQ Queries" reads an entry on the ADO.NET team blog. [Editor's note: The preceding italicized text was changed due to an error; the italicized text that follows was also changed and refers to this same blog post. We apologize for the errors.]

The post explained that the EF team at first wanted to address these core library updates with a separate, full release of EF instead of waiting for .NET 4.5. The June EF Community Technology Preview was the result, offering up that "The Enum data-type is now available in the Entity Framework."

Well, not so fast. "While we are still pursuing this option it has become clear that from a technical standpoint we are not ready to achieve this immediately," the post said. No details about the technical problems were mentioned. The aforementioned list of EF enhancements "will reappear in a preview of Entity Framework that we will ship alongside the next public preview of .NET 4.5," the post said. The post didn't indicate when that might be.

The .NET Framework 4.5 developer preview was introduced in September at the BUILD conference.

What do you think of the EF and .NET Framework previews? When do you think you'll finally get that enum support? Comment here or drop me a line.

Google, Apple Play Catch-Up to Microsoft (for a change)

I'm no Microsoft fanboi, but I noticed an interesting tidbit when I recently wrote a news article about Google Cloud SQL, which adds a MySQL database service to the company's App Engine development stack.

In the comments section of the blog post announcing the new service, was this from reader Jeff King:

"Microsoft has had SQL Azure for ages so why would you need this?"

Now that's a switch. Usually it's the other way around: The slow, ponderous, bureaucratic, out-of-touch Redmond software giant is chastised for being behind the times and playing clumsy catch-up to the hip, nimble Web 2.0 pioneer.

Indeed, SQL Azure was introduced in March 2009. Truth be told, after Amazon basically pioneered the cloud phenomenon in 2006, Google beat Microsoft to the punch in the fight for the sky when it introduced App Engine in April 2008, about six months before Windows Azure was unveiled.

But, looking at the database component, it's clear that Microsoft has had a leg up on Google, which heretofore offered a datastore with a syntax similar to SQL called GQL. OK, how many of you developers have liked, or even used, GQL? Raise your hands (or flame me; your choice).

"One of App Engine's most requested features has been a simple way to develop traditional database-driven applications," said the Google Cloud SQL program manager in the previously mentioned blog post. Well, yaaah!

And today I noticed a news report that Apple is preparing to launch its iCloud. I know the products don't really compare--with Apple's focus on music and consumer entertainment as opposed to enterprise development--but launching an iCloud service in late 2011 seems a little iBehind.

And stodgy old Microsoft seems to have acquitted itself well in the cloud despite its late start, judging from this recent Ars Technica headline: "Windows Azure beats Amazon EC2, Google App Engine in cloud speed test."

I've even noticed some positive buzz about Windows Phone in the media as of late. Is Microsoft finally turning things around, like a huge supertanker that takes miles to change direction? Will it (gasp!) become cool? Well, let's not go overboard here.

What do you think about Microsoft: dying dinosaur or comeback kid? Comment here or drop me a line.

Not Your Typical Data Driver Column

Dear ‹FirstName>,

In these trying times you occasionally just need to take a break from the business of data and have a good laugh. Which is what I did when I received the following e-mail, purportedly from a real data-related vendor. I'll protect that innocent by anonymizing the company/personal details in italics, but otherwise the message is presented as received:

Dear ‹FirstName›,

We're ‹insert emotion› to announce our research is nearly complete. In just a few ‹random time duration›, we'll be announcing the new Company Name Telepathy Source and Destination, allowing the everyday man and woman to read minds into an SSIS data stream.

Imagine being able to:

Read the entire encyclopedia in a matter of minutes

Output your wife's thoughts to find out how she really feels

Learn a new skill in seconds like Neo from the Matrix

Over the past week we've run a contest to see who can be the first to view this amazing research and I'm happy to announce that Person's Name is our winner. If you are Person's Name, please click the below link to see our research. If you are not Person's First Name, please do not click below. We operate solely on the honor system at Company Name.

Person's Name Click Here

‹Emotional Stub›,

CEO's Name, Founder of Company Name

So, I don't know if it was meant to harvest contact information or install malware or what, but it certainly provided some much-needed ‹insert pleasant emotion› to the Data Driver. What's the clumsiest troll you've ever received? Comment here or drop me a line.

Windows 8 Ups the Data Transfer Ante

Talk about driving data: the audience broke into applause at last week’s BUILD conference when some of the new blazing fast data transfer capabilities were demonstrated by Microsoft’s Bryon Surace during a keynote address.

“With Windows Server 8, we can use multiple NICs [network interface controllers] simultaneously to help improve throughput and fault tolerance,” Surace said.

To demonstrate the new speedy data-transfer capabilities, Surace used a server running Hyper-V with two virtual machines, one of which was connected to two disks. One disk was connected using a 1GB Ethernet connection, a setup he described as “very typical, very commonplace in today’s environment.”

The other disk was connected “using multiple high-speed NICs that are leveraging SMB 2.2 multi channel and RDMA [remote direct memory access].” Starting up a SQL load generator and going to a performance monitor, Surace pointed out how the 1GB Ethernet card was transferring data at less than 100MB/sec., which he said was “pretty typical.” The second disk, however, was transferring data at more than 2GB/sec. That’s when the applause broke out.

“Now, previously, these technologies were only available in high-performance computing, but now with Windows Server 8, we're building them for one of the most common roles in Windows, Surace said. He went on to show that the NIC wasn’t saturated, but rather was using only about 15 percent of the available throughput.

“This is a clear indication that we haven't even scratched the surface of what's possible with Windows Server 8,” he said. “And as we move over and take a look at the performance, we're only using about 1 percent of the CPU on the server to be able to push this throughput.”

Surace also demonstrated the simplified storage array management capabilities of Windows Server 8. For this, he used a server connected to 16 SSD hard drives, with no specialized controllers, “just a bunch of disks, or JBOD, directly connected to our server and being managed by Windows.” He noted how the disks were used to create a storage pool for which some space was carved out and represented as a drive on the server. He also showed file shares connected by the “improved SMB 2.2 protocol.”

“So, the key here is you don't need a PhD in storage, Surace said. “You can simply attach just a bunch of disks to Windows and have it all managed and deployed right there.”

The full keynote can be viewed via Microsoft’s Channel 9 video service.

Is Microsoft Really Embracing Big Data?

In the continuing effort to reach détente with the open source community, Microsoft is making inroads in the big data movement.

Last month, it released CTPs of Hadoop connectors for SQL Server and Parallel Data Warehouse "to promote interoperability between Hadoop and SQL Server." That's not so surprising--the Redmond software giant has made similar moves with other open source technologies.

But now there are signs the company may even be opening up to the so-called "NoSQL" data store world!

Microsoft's MSDN Magazine may be a harbringer of this trend. Up until now, there basically have been only two articles in the publication that dealt with NoSQL products. And both of them discussed the MongoDB product. One was actually a three-part series of articles by columnist Ted Neward, at the time an independent consultant. The other article was by developer evangelist Brandon Satrom, actually a Microsoft employee.

But for the November issue, there are two articles slated on the subject: an exploration of document databases by columnist Julie Lerman and an article on embedding the RavenDB data store into an ASP.NET MVC 3 app by Justin Schwartzenberger. And magazine editor Michael Desmond interviews the two in an editor's note titled "NoSQL? No Problem." I can't go into more detail now because the articles haven't been published (I just know about them because I'm technical editor of MSDN Magazine).

But is it just a coincidence that there have basically been only two previous NoSQL-themed articles and the November issue alone will double that? We'll see.

What do you think Microsoft is up to? Comment here or drop me a line.

Looking at Juneau's Integrated Database Development

One of the nice things about my day job as technical editor at MSDN Magazine is getting early looks at cutting-edge technologies and how-to guidance from some of the top experts in the world.

This month, for example, Jamie Laflen and Barclay Hill explore “The ‘Juneau' Database Project,” which promises that “you can now perform your database development in the same environment as your application development.” That sounds nice. No more jumping around from one tool to another.

I found it particularly intriguing that the new Database Project in the next version of Visual Studio enables offline SQL Server development. The two SQL Server Developer Tools experts explain this “project-based development” provides the following advantages over using a shared live database:

  • Isolation of developer changes
  • Rich T-SQL editing support
  • Verification of source prior to deployment and enforcement of team coding standards through code analysis rules
  • Automated migration-script generation

Furthering the move to more self-contained development is SQL Server Express LocalDB, as introduced in a sidebar. It provides a kind of simplified user instance and lets you develop against SQL Server Express without having to fuss with managing a full-fledged desktop Express instance, cutting way back on setup time. Check out the article for more technical details. Your job as a .NET/SQL Server developer is about to get a lot easier.

What are you looking forward to in Juneau? Comment here or drop me a line.

New NoSQL Language Unveiled As Debate Rages On

Pretty much every blog, article or discussion you see about the SQL vs. NoSQL debate includes sage advice from a reasonable voice of authority along the lines of something like this:

Whoa! Let's calm down. No need to fight. It's not a which-is-better issue, because each (tool/approach/language/philosophy) has its use. They should be used together as needed to solve different kinds of problems according to their strengths ...

And so on.

So it was interesting to read a comment on a blog post that went against that grain:

I wish it was as simple as SQL & RDBMS is good for this and NoSQL is good for that. For me at least, the waters are much muddier than that.

Tony Bain made that comment on a blog post by Conor O'Mahony titled "The Future of the NoSQL, SQL, and RDBMS Markets." Bain goes on to discuss the issue in detail, with much of the discourse from the perspective of a database developer. It's definitely worth reading by you data devs. It's also noteworthy that the blog posting was prompted by an article in The Register with the subhead "World says 'No' to NoSQL."

Were it that easy. Just a week or so earlier, in fact, there was much buzz generated when Couchbase released a "flagship NoSQL database" and an entirely new NoSQL query language called UnQL.

Does that sound like the desperate last gasp of a major player in a dead movement? Or will we one day look back and recognize it as a major step in an industry transformation?

You tell me. Comment here or drop me a line. I'm just happy that Couchbase provided some pronunciation guidance, a pet peeve of mine. UnQL is pronounced like the word "Uncle."

How are Database Developers Doing, Salary-Wise?

I noticed in the comprehensive 16th annual IT Salary Survey that database developers lost their No. 1 spot in the category of average base salary by job title, actually falling three rungs down the ladder to No. 4.

Not that $95,212 is that bad. But still, that seemed like kind of a big drop in statistics that don't usually change that much from year to year. In fact, editor Michael Domingo said "Database programmers have been fairly consistent in the rankings, but dropped from the top spot to fourth from a dollar perspective. Still, based on percentages, they managed to go up nearly 7 percent from last year's result." Besides being consistent, database programmers "often rank highest," Domingo said in the more extensive PDF document, downloadable with registration.

So, what does a healthy 7 percent average salary hike combined with the reduced job title salary ranking really mean? It looks like that, while data devs are doing OK, others--especially networking project leads--are just doing a little better.

Indeed, when it comes to "salary by technology expertise," Domingo said, "The biggest gains from a year ago are those with database development skills, earning 6.2 percent higher." In that category, the average salary for those with database development skills was $92,460.

Another survey, conducted by Microsoft Certified Professional Magazine, also had good news for database developers. Domingo edited this one, too (the guy is everywhere). "Network project leads also often do well, but in the scheme of things, it's the DBAs and database developers who came in right above on the salary scale," he said. "DBAs and developers often tell us that they're well compensated and happy with their pay, and this year is no different. It's data, after all, that is at the heart of many businesses and good data people are often plied with incentives to either stay put or lured away to companies who can afford to pay higher salaries."

Whew! I guess that initial ranking drop I mentioned isn't that worrisome after all. Data still rules, and pays the big bucks. Now, for me, it's with relief that I return to wrestling with outer joins and normalization in that "Become a Database Developer in 21 Days" course I paid so much for.

What the heck is a tuple? Clue me in or comment otherwise, or drop me a line.

When Beta Apps Wreck Your System: A SQL Server 2008 R2 Eval Lesson

OK, I need a little help here. I earlier wrote about a nightmare I endured (along with many others) with the evaluation version of SQL Server 2008 R2.

I was surprised to be ripped by readers. Turns out it was my fault. You're never supposed to install beta apps on a system you might want to use again. That was news to me. One reader wrote:

"By its very nature eval software is not to be installed on any machine you don't care about needing to be rebuilt from the ground up. Hasn't anybody ever read the warnings included with installation of eval software? If you are "experimenting" with new software on a machine that cannot be wiped and rebuilt then the onus is on YOU not Microsoft."

Another concurred:

"When using evaluation software you should always walk in the path that what you are installing it on may not be capable of running afterwards, no matter who wrote the software."

How did I miss this? Where are these "warnings"? Do Microsoft or other major vendors actually say that you should only use this stuff at your own risk because it might trash your computer? I looked around quickly on Microsoft's site but didn't see these warnings. Do they pop up when you install the software or are they in the EULA or somewhere else? I'd test this out by installing something and seeing what warnings I receive, but I'm afraid to now. Maybe I just click too quickly through all the screens during setup and have missed these warnings.

Anyway, reader No. 1 suggested using virtual machines. I've never tried these, frankly, so I'm looking for some advice. He mentioned a free server from Microsoft, what I presume is Virtual Server 2005 R2. Does anybody have any real-world experience with this? I have an underpowered Win 7 laptop so I'm kind of concerned about any additional load it will put on the system. And there must be myriad other details that real users can relate that aren't found in the documentation.

Also, are there any other free alternative virtual servers that anyone has hands-on experience with that might be useful for testing software?

Another reader mentioned he uses partitions for testing this stuff. But I've had bad experiences with partitioning disks before, too (hmm, maybe it's just me). What about you? Any suggestions or experiences to pass along with partitioning, or partitioning vs. virtualization?

So basically I'm looking to share with everyone any tips, warnings or ideas about virtualization or partitioning--or alternative methods to test software--that you'd care to provide. Please comment here or drop me a line.

And the "SQL Server 'Denali' Must/Must Not Support XP" Debate Goes On

A couple of interesting announcement were made since I wrote about how some developers were clamoring for Windows XP support in the next version of SQL Server, code-name Denali.

First, in a Monday keynote address at Microsoft's Worldwide Partner Conference (WPC), the company announced that XP's "end of life" would occur in 1,000 days, on April 8, 2014.

Second, on the same day, at the same event, Microsoft announced the availability of the Community Technology Preview 3 of Denali. It's getting closer and closer to final release.

The XP/Denali debate continued on Microsoft's site after my blog was published, with readers chiming in on the issue even though the post announcing that XP wouldn't be supported was nearly a month old. "I'm going to disagree with the crowd, I think support for XP should be put in place," commented one reader last Friday.

The lively exchange among readers continued in the comments on my blog post, with a mix of opinions. "Obviously seems wrong to support something that's now obsolete," wrote one reader. "Time to cut the cord," wrote another. "Definitely Windows XP has to be supported," wrote yet another.

So it's still a hot-button issue, even though, with the Denali CTP3, the point seems moot.

Me? I've come down firmly right in the middle of the fence. I still have an XP machine, and it works fine with several modern apps. And a couple years ago, I was still advocating XP as the best OS in a debate with three other journalists on another IT publication's Web site.

But I also have a Win 7 machine, and I love some of its more advanced features. And with the economy imploding, even cash-rich Microsoft has to pick its support spots these days.

As I write this, though, I notice my XP desktop lies dormant at my feet, while for quite some time I've had its monitor plugged into my Win 7 laptop for dual-display.

I guess I've fallen off the fence.

What do you think? Comment here or drop me a line.

SQL Server Devs Clamor for XP Support in Denali

When I first glanced at the proposed list of OSes to be supported in the next version of SQL Server, code-name Denali, I actually thought: "Windows XP isn't supported? That's odd. There are a lot of XP machines still out there."

My immediate second thought was: "No, that's cool. It's getting too long in the tooth. Time to move on." But it appears a lot of SQL Server developers agreed with thought No. 1. Yes, the nearly 10-year-old OS still has its proponents in the dev field (it's hard to believe XP was actually released to manufacturers before we all knew about Osama bin Laden).

Case in point was this reader's response to the blog announcing Microsoft's supported OSes and upgrade plans:

"Sadly, that Windows XP is not supported. I know many developers use SQL Server Express + SSMS on their Windows XP corporate workstations. And they do not plan to move to Windows 7 soon. I do understand, that life is going on, but still ... I wish it would support XP."

There were many more posts like that one, leading to a good deal of give-and-take among the readers on both sides of the issue. Two readers reported companies they worked at (or recently worked at) still had more than 10,000 XP machines!

Comments like those made me gravitate back to my thought No. 1. After all, Wikipedia says, Microsoft continued to sell XP through certain channels up until the beginning of 2010. And the Denali CTP was released later that year. Isn't it a bit premature to abandon the vast XP user base in introducing an important new SQL Server release when XP hasn't even been officially expired for much more than a year and half? Granted, I don't know when Denali will be officially released, but a lot of people think it might be this year.

But other readers make good points, too. Like this:

Good list and I support it. No reason to go backwards anymore. Those companies that still run XP on every desktop and mandate it, or have SQL2K, aren't going to run to Denali. If they think they need it, they'll make exceptions for the people that need it.

Any IT professional that wants to work on Denali, but has XP at work. Either invest in a machine that you can run it on at home or learn to set up a VM, but there is no reason for MS to invest time or testing efforts into supporting XP at this point.

Those kinds of comments made me reconsider thought No. 2.

Ah, I'm just too darned wishy-washy. Decide for me. Which should it be? Comment here or drop me a line.

NoSQL Ascension Highlights Developer Survey

I found it interesting that Evans Data chose to lead with the growth of NoSQL in the enterprise when it began hawking its latest North American Development Survey today.

Not programming languages used, mobile development or even the cloud. But rather, the ascension of NoSQL. What does this prove? It's the data, stupid.

The survey reported that 56 percent of respondents were using some flavor of NoSQL and 63 percent planned on doing so in the next two years. The reason, Evans Data, said, was scale. Massive amounts of data become awkward to handle in traditional relational database schemas. And these huge depositories, spawned on explosively growing Web sites such as Google and Facebook, are becoming more commonplace in the enterprise.

"The advent of Big Data is driving adoption of NoSQL, and this is especially true in the corporate enterprise," the company said in a news release.  "While it may have got its start on the Web with innovations like Big Table and MapReduce, it's the enterprise that can most benefit from NoSQL and developers realize this across all geographical regions."

In fact, Evans Data said enterprise adoption dwarfed that of the "general developer population," where only 43 percent of respondents expected to use NoSQL.

Microsoft has to be paying attention to this. They may have been late to the Web, mobile, etc., but the enterprise has always been their stronghold, in SQL Server and many other technologies. If they weren't worried before, they have to be now.

For an interesting, alternative take on the reasons for the growth of the NoSQL movement, read this blog by database expert Andrew J. Brust on the Redmond Developer News site.

Then chime in with your own thoughts about this upsurge in popularity. Comment here or send me an e-mail.
