What is Oracle Data Access Components?
Oracle Data Access Components (ODAC) is a library of components that provides native connectivity to Oracle from Delphi, C++Builder, Lazarus (and Free Pascal) for 32-bit and 64-bit Windows, macOS, and Linux platforms. The ODAC library is designed to help programmers develop faster, cleaner and more native Oracle database applications.
*Wide Coverage of Oracle Features By providing access to the most advanced database functionality, ODAC allows developers to harness the full capabilities of the Oracle and optimize their database applications. ODAC stands out as the set of components with the widest support of Oracle functionality. It is the only component to support Oracle distributed transactions and implements support for controlling statement caching , OCI pooling , and Oracle Advanced Queuing. View the full list of supported Oracle features in Features.
*Native Connection Options ODAC offers two connection modes to the Oracle server: connection through the Oracle Call Interface and direct connection over TCP/IP. ODAC-based database applications are easy to deploy, do not require installation of other data provider layers (such as BDE), and tend to be faster than those that use standard data connectivity solutions. See the How does ODAC Work section.
*Oracle Advanced Features Support ODAC has extra components designed to simplify some tasks and support Oracle-specific technologies. Particularly, OraScript serves to execute series of SQL statements, OraLoader serves to load external data into Oracle databases, OraeAlerter and OraPipe transfer messages and data between connections or client applications, and so on. ODAC includes set of classes designed to work with Oracle Advanced Queuing technology.
*Cross-Platform Solution for Delphi, C++Builder, and Lazarus ODAC is a cross-platform solution for developing applications using various IDEs: RAD Studio, Delphi, C++Builder, Lazarus (and FPC) on Windows, macOS, and Linux, for both x86 and x64 platforms. ODAC also provides support for the FireMonkey platform, which allows you to develop visually spectacular high-performance native applications for Windows and macOS.
*Compatibility with Other Connectivity Methods The ODAC interface retains compatibility with standard VCL data access components like BDE. Existing BDE-based applications can be easily migrated to ODAC and enhanced to take advantage of Oracle-specific features like alerts, pipes, and the direct-path interface. Project migration can be automated with the BDE Migration Wizard. Find out more about Migration Wizard in Using Migration Wizard.
*Development and Support ODAC is an Oracle connectivity solution that has been actively developed and supported since 1998. ODAC comes with full documentation, demo projects, and fast (usually within one business day) technical support by the ODAC development team.
