[Kudos] from latest db4o event in Glasgow

These are some comments after the latest db4o event in Glasgow. Jim Paterson was the speaker an he did a great job: "This was a very good session, I enjoyed it very much. db4o is certainly something worth looking into for future projects." Martin Bell "If you are a serious .NET web developer thuis session is (was) a must." Frank Kerrigan "This was a super session - I discovered something new that I can download and use today. The presenter had plenty of content having delivered this session elsewhere. Kudos to Colin for making this event happen - if you weren't there, you missed a great session that could save you time during the early stages of your projects."

[Kudos] db4o is definitely worth taking a look at

I use db4o (GPL) within some projects. It is a really great peace of software. If you don’t need a relational database (and often you don’t!), db4o is definitly worth taking a look at it.

It is possible to use db4o with a client-server architecture. Often this is a faster and easier way to use db4o than some sort of RMI. Applications that shall use a common database but run on different machines (rich clients within a LAN) can benefit from those features of db4o.
For the next version (6.4) the performance of client server architectures is within focus - with success:

[Kudos] db4o worked like a charm

Last night, I was lucky enough to attend a Scottish Developers meeting in Glasgow [...] Whilst I had thought that the session was going to be all about object database in Java, it turns out that db4o has a .NET implementation too.  And it supports the .NET Compact Framework, i.e. mobile devices.  Speaker Jim Paterson did a really good job of explaining db4o, its use, its positives and its negatives.

Of course, the first thing I did today was go off and download db4o and set about a simple “hello world” style example.  True enough, everything that I saw last night worked like a charm.  In fact, here’s the C# that I threw together in about 5 minutes...

[Kudos] Software that makes data integration much easier can conquer the world

The db4o series on developerWorks is intriguing and easy to read. I didn't know anything about db4o before reading it, but the first article starts at the bottom level. db4o is an object database specifically oriented toward Java and C#. It's designed to eliminate the object-relational impedance mismatch by...tossing out the "relational". Save an object. Retrieve it. According to the articles, db4o certainly meets the goal of higher developer productivity.I'm still skeptical about how it compares to the usual SQL databases in several ways: storage efficiency/data duplication, performance, security, scalability. It was also interesting to note in the later articles that db4o faces some of the identical difficulties as ORM tools: lazy loading, inheritance hierarchies, collections of collections (of collections of collections), refactoring, mutually-referenced objects. As an object database closely integrated into code, db4o has distinct advantages when confronting these difficulties, though. The fact that every ... Read the rest of entry »

[Kudos] db4o usefulness

"Now, I am really raising two separate issues here. On one hand, I am talking about syncronising two separate computers and on the other, I am talking about a seamless experience between online and offline applications. I think the first is mostly being taken care of. The second issue has some solutions becoming available also. This is where I see stuff like Google Gears, Adobe Air and db4o especially their db4o replication system proving to show their usefulness."

[Kudos] db4o feels right

"db4objects - I played a bit with this Java and .NET open source object database engine and it feels right. It also has great documentation. If you are looking for some code to play with, this is it."

[Kudos] first choice for fast data storage

“db4o is my first choice for fast data storage, it can be set up in a matter of minutes and works great without any additional tuning. No more object-relational mapping to set up and maintain. I use it for embedded applications and as a replacement for existing providers in ASP.NET and ELMAH”
