A relational database performance considerations for numerical simulation backend storage

Problems of effective numerical calculations in scientific applications are caused by non-optimal front-end application code or ineffective system of scientific data management at back-end. In this article author presents some aspects of performance problems when relational database is used as backend storage based on real cases. Presented examples come from simulated environments with large load and many queries executed. These examples can reflect real problems with data processing in numerical calculations on data extracted from MSSQL Server database.
