DataSurge: When Performance Matters

Visa International

Visa International had substantial problems with the performance and scalability of one of their applications.

Knowing of our track record, they hired DataSurge to straighten out the problem.

We analysed the system and attributed the lack of performance to the way they were accessing data, the front-end tools they were using to write the application and to the indexing strategy and table design of the underlying database.

We proved that the data access time could be reduced from 30 seconds to 15ms by realistic volume prototyping using a more suitable database design, implementing efficient indexing and using alternative data access techniques.
