I just recently did some evaluation on OLIVANOVA along with TimesTen In-Memory Database as the persistence layer. OLIVANOVA is a model driven software development environment that generates code for business software. Certified database management systems include all major relational database management systems such as Microsoft SQL Server, Oracle, DB2 and so on.
One of OLIVANOVA‘s customers required instant responsiveness and very high throughput. So, this was a welcome opportunity for me to evaluate TimesTen, an In-Memory database. I created the model, generated the source code and specified the driver and connection string. In a few minutes I was able to test the application against TimesTen.
It works great and the responsiveness is just awesome. TimesTen can be set-up as an embedded or standalone database. It can also be used as an in-memory database cache for Oracle databases.
