How is Exadata different from TimesTen In-Memory Database ?
Exadata, just like RAC, is a highly scalable system that can be used to increase throughput to unparalleled levels. TimesTen’s unique value is in its very low response time. TimesTen runs in the application tier. To get the best performance, it can also be embedded with the application. TimesTen delivers responses to SQL requests in microseconds (4 micro-seconds for a SQL SELECT statement and 14 micro-seconds for a SQL UPDATE statement). This is essential to real-time applications that require instantaneous response time for phone call routing, authentication and authorization, real-time billing, securities trading, fraud detection, online banking, etc.
