Database tuning and application consulting

As a consulting partner of a leading database company we were assigned to a database tuning project at a mobile telecom company. The project target was one of the most challenging technology problem among our assignments. The credit availability of pre-paid mobile phone customers were to be verified in real time on each initiated outgoing call. A unique large database running on a cluster of computers was analysed and fine-tuned to achieve a good response time for the majority of calls. Special tuning methods and tools were developed by us in order to be able to measure the individual processing time of the database engine. As a result several architectural and hardware options were suggested to the customer to cope with the predicted increase of load. Project based in Budapest / Hungary.
