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 ODBC (Open Database Connectivity), OCI (Oracle Call Interface), Oracle Pro*C/C++ (precompiler for embedded SQL and PL/SQL instructions in C or C++ code), JDBC (Java Database Connectivity), and PL/SQL (Oracle procedural language extension for SQL).
This Preface contains these topics:
Oracle TimesTen In-Memory Database PL/SQL Packages Reference is a reference for programmers, systems analysts, project managers, and others interested in developing database applications using PL/SQL. This manual assumes a working knowledge of application programming and familiarity with SQL and PL/SQL to access information in relational database systems.
TimesTen documentation is available on the product distribution media and on the Oracle Technology Network:
http://www.oracle.com/technetwork/database/timesten/documentation/
Oracle TimesTen In-Memory Database PL/SQL Developer's Guide is especially relevant.
Oracle documentation is also available on the Oracle Technology network. This may be especially useful for Oracle features that TimesTen supports but does not attempt to fully document:

In particular, the following Oracle documents may be of interest.
Oracle Database PL/SQL Language Reference

Oracle Database SQL Language Reference
Oracle Database Reference
In addition, numerous third-party documents are available that describe PL/SQL in detail.
