Abstract [en]

The main purpose in this degree thesis is to investigate changes in performance when introducing a newly produced Real-Time database in one of CC Systems products, the Diagnostic Runtime Engine, DRE. The thesis is a collaboration between CC Systems, creator of DRE, and Mimer AB, developer of the Real-Time database.

The result reveals that the time spent on database access is considerably lesscompared to the originally used database. The research has lead to several additional requirements on the real-time database and these are presented as part of the result in this thesis. The additional features will help making the product more suitable for DRE and similar applications.

Additional research is required to be able to recommend the use of this product or not. Primarily the performance in another operating system, Windows CE, but also the introduction of additional features should be investigated. Part of this new functionality is included in the first formal release of the product, likely to be introduced in late 2007. Further research is continuing within both companies involved.

Product investigated:Mimer SQL Real-Time Edition C API, 9.3.7D (Beta Version). A relational database that handles hard and soft real time requirements in anapplication. It uses standard SQL-queries for the soft Real-Time and a new Real-Time API for the hard real time.
