Startup Developers Gathering Helsinki August 27, 2008

Next SDG meetup will be held in Korjaamo. Join us to talk about databases with beer. Miku (Mikael Kopteff) will be giving introduction to the topic. I hope that won`t be a monologue! Let`s make this as conversational as possible (includes cutting Miku out after 15min). Here is how Miku introduces us to his presentation:

Alternate object persistence systems

Relational databases are the de-facto standard persistence systems for modern applications written in object-oriented languages. The use of these tools is usually justified by the use of SQL, standardized toolsets and abstraction from the programming language. The usage of a relational database still creates a impedance mismatch problem between the relational data model and an object-oriented language, that is traditionally solved with ORM-tools or manual object-to-relational mapping. As an introduction to the SDG I’ll go through some of the alternatives for relational databases, mainly object databases. The idea of this session is to have a discussion about these alternative systems and the benefits they might offer.

The introduction will include the following topics:

-What is object persistence?
-What are object databases?
-What does an application benefit from an object database?
-Differences between object databases and ORM tools
-What other persistence solutions are available?
-Different use cases for persistence systems?
