As a business technology architect helping clients transform their applications, I sometimes feel more like a software archeologist. It is very interesting to see how heterogeneous the technology landscape is and how diverse it is being used at customers of all size and industry sector. But, there is one common question that we see throughout our engagements: “How can we transform this heritage to a future state?” and “Can you help us keep what’s important, but make it easier to manage?”.

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. The JSF client as well as the business logic have been deployed on a JBoss application server.

If you want to learn more about model driven software development and how to create your first “Hello World!” example, then please have a look at these tutorials. They explain how to start using the OlivaNova Modeler.

The OLIVANOVA Evaluation Version is available from the CARE website. This site contains two tabs:

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).
