27.1 Introduction

The Oracle TimesTen In-Memory Database TimesTen provides real-time data management. It provides application-tier database and transaction management built on a memory-optimized architecture accessed through industry-standard interfaces. Optional data replication and Oracle caching extend the product to enable multi-node and multi-tier configurations that exploit the full performance potential of todays networked, memory-rich computing platforms. Oracle TimesTen In-Memory Database is a memory-optimized relational database. Deployed in the application tier, TimesTen operates on databases that fit entirely in physical memory using standard SQL interfaces. High availability for the in-memory database is provided through real-time transactional replication. TimesTen supports a variety of programming interfaces, including JDBC Java Database Connectivity and PLSQL Oracle procedural language extension for SQL.

27.1.1 Concepts

The TimesTen concepts map the Oracle Data Integrator concepts as follows: An Oracle TimesTen In-Memory Database instance corresponds to a data server in Oracle Data Integrator. Within this database instance, the databaseowner pair maps to an Oracle Data Integrator physical schema. A set of related objects within one database corresponds to a data model, and each table, view or synonym will appear as an ODI datastore, with its attributes, columns and constraints. Oracle Data Integrator uses Java Database Connectivity JDBC to connect to an Oracle TimesTen In-Memory Database ODBC DSN.
