TimesTen

From Wikipedia, the free encyclopedia

TimesTen provides a family of real-time infrastructure software products designed for low latency, high-volume data, event and transaction management. Unlike conventional infrastructure software, TimesTen’s products are optimized for deployment within the application tier. They are used intensively in the telecom and financial markets because of their very high performance and robust reliability. They are increasingly being used more broadly for mid-tier data management, for example in e-commerce applications and service-oriented architecture (SOA) infrastructures, because of their performance, low maintenance, flexibility, and reliability.

[edit] Product Information

TimesTen's core DataServer product uses in-memory database technology to speed access to data. Indexing, query optimization, and storage management, for example, are designed specially for in-memory data access. The result is extremely high throughput and low, predictable response times, even on commodity hardware. The DataServer product also incorporates robust replication facilities, non-blocking operation, and an event-notification mechanism that works together with materialized views to convey changes to other systems.

TimesTen also offers a Cache product that interoperates with an Oracle database backend, using one of several protocols, to cache frequently used data in TimesTen. SQL predicates can be used to specify what data is cached, or data can be loaded into the cache on demand (and later automatically aged out). Data can be changed in the cache, with writes being propagated synchronously or asynchronously back to Oracle.

TimesTen's third product, Transact, uses asynchronous technologies such as replication, messaging, and buffered disk writes, combined with intelligent sequencing and replay, to provide synchronous guarantees with no waits. The product is designed for applications that need high-performance and no data loss.

TimesTen products run on the major Unix/Linux platforms and on various Windows platforms, in both 32-bit and 64-bit modes. Standard support includes ODBC and JDBC interfaces and the SQL query language.
