Just recently, I had been asked to compare the performance of Oracle 10g and Oracle TimesTen In-Memory database. We wanted to evaluate to what extent the performance of a mission critical system could be increased by using an in-memory database like Oracle TimesTen compared to a “regular” RDBMS like Oracle 10g. I used a sample application generated from OLIVANOVA in order to compare these different scenarios. The application is based upon a three-tier architecture with a JSF client, J2EE business logic and a RDBMS.

While playing around with some XMI (XML Metadata Interchange) importing/exporting functionality, I found this great blog: Modeling LAnguages (original URL https://modeling-languages.com). His service to convert from one XMI format to another is just awesome. Have a look at this site: XMI2 - A tool for exchanging UML models among CASE tools (original URL https://modeling-languages.com/content/xmi2-tool-exchanging-uml-models-among-case-tools).
