Microsoft to Open Source FoxPro 172

Apparently ESE stands for Extensible Storage Engine as well...so I'm gonna have to say Exchange doesn't use JET.

The relevant part of the actual announcement on Microsoft's site [microsoft.com] reads "To reiterate, today we are announcing that we are not planning on releasing a VFP 10 and will be releasing the completed Sedna work on CodePlex at no charge. The components written as part of Sedna will be placed in the community for further enhancement as part of our shared source initiative. You can expect to see the Sedna code on CodePlex sometime before the end of summer 2007."
Shared Source [microsoft.com] is not Open Source.

So it's apparently a flavor of JET...but different.
I could "see" them opening JET Red (Access) in about 10 years, because there are no plans to make it 64 bit, but not JET Blue (ESE/Exchange). That'd open up Exchange and MS wouldn't want to do that.

That seems pretty definitive to me.
For clarification: Sedna (the stuff that's going into CodePlex) is not now (nor was it ever intended to be) the next version of Visual Foxpro. It's just a set of VFP-based tools intended to help current VFP developers to make better use of new features in Vista/SQL Server/etc...
Meanwhile, VFP 9 is getting a final service pack and then that's it as far as Microsoft is concerned. There's certainly no plans to open-source the IDE or the VFP engine because, frankly, Microsoft would never do that. Some of the technology (and people) from VFP is going towards the LINQ project, but

That is incorrect. FoxPro only reads only the data it needs.
I know this will come across as flamebait, and I'd normally not say this, but anyone who claims that FoxPro is fast is a hobbyist programmer. It's simply not fast by any imaginable standard other than the trivial case of small files on a single user's drive.
Another lie. I've written FoxPro apps that are used in 100+ multiuser environments with multi gigabytes of data. Fast as hell.
I'm not saying it's better that client-server but to say FoxPro is slow is wrong. You can write crap applications in any language you know.

So, you are mistaken. Either that, or my machine downloaded 240 MB in under a second. Sorry, our network isn't that fast. *smile*
I don't know much about file servers, but the entire index file does not need to come down. Not sure if that is a boon of the file server or of Foxpro, but I have been fighting that myth for ten years -- Foxpro does NOT pull entire files down...neither the index files nor the data file.
Let's get some other "duh" stuff taken care of. ANY system will be slow if you pull down a lot of data. That's because the data is coming down. It has to traverse the network to become truly local. If it isn't coming down, like some sort of DataReader thingamabob, then OK, it isn't down. But then don't try joiing that table to another local one, because then you'll just have to wait _then_.
Foxpro is incredibly fast. We have custom applications totalling more than 600,000 lines of code. Everything from old DOS-based input screen to an imaging system (scan, classify, viewing) housing more than 5 million images/files across 2 SQL Server databases (yes, VFP does wonders with SQL Server databases as well). The file-based DBF problems arise as they would with any file-based solution: size limits, contention issues, corruption, etc. But we have over 50-60 users regularly pounding our system, a mix of DBF data and SQL Server data, and it works pretty darn well.
Foxpro's other advantage is what it does with client side data. I can read in an XLS file (one line of code), bring in data via a SQL Server query (3 lines of code), and query a local DBF file (one line of code). Each query will reside in it's own local cursor which can then be indexed, browsed etc. Even better, those cursors can then be joined, filtered, and queried to build another cursor with all of that data brought together. I hear Microsoft is still working on a local engine with that kind of power for
Foxpro has a lot of problems, sure, and I am digging
And one more time: FOXPRO DOESN'T PULL DOWN THE WHOLE INDEX FILE WHEN DOING QUERIES! *phew* *smile*

Yes, I used FoxPro back in the early nineties. It was a great product under Fox, but when Microsoft purchased it, they supported it only for a while, then let it languish while they pushed Access (an UTTER POS with all the "reliability" and brain-dead design decisions Microsoft is known for).
I was at a computer show in San Francisco standing at the FoxPro booth actually when I heard that Microsoft had bought them.
But I don't think the "Jet" engine came from Foxpro. I might be wrong about that. I think the Access engine and the FoxPro engines were separate for a long time. A quick Google indicates that Microsoft bought Fox for their "Rushmore" database technology which ended up being included in Jet.

A few years ago, I ran into a couple of FoxPro-based applications and I learned a little about the history of the product.
FoxPro was rather popular with application writers and there are still a lot of small business applications based on it. Apart from the technical merits, it had one big advantage over MS Access: you could bundle FoxPro with your application for free, while Access required an Office license for each PC.
Microsoft bought the company mainly to destroy a competitor. They ended up supporting the product for a long time, probably due to support contracts.
