Oracle Data Access Components (ODAC) is a library of components that provides native connectivity to Oracle from Delphi and C++Builder including Community Edition, as well as Lazarus (and Free Pascal) on Windows, Linux, macOS, iOS, and Android for both 32-bit and 64-bit platforms. The ODAC library is designed to help programmers develop faster and more native Oracle database applications.

ODAC, a high-performance and feature-rich Oracle connectivity solution, is an efficient native alternative to the Borland Database Engine (BDE) and standard dbExpress driver. It provides both possibility of connection to Oracle by means of native Oracle data access and direct access to Oracle from Delphi without Oracle Client.

Native Connectivity to Oracle
ODAC-based DB applications are easy to deploy, do not require installation of other data provider layers (such as BDE or ODBC), and that's why they can work faster than the ones based on standard Delphi data connectivity solutions. Moreover, ODAC provides an additional opportunity to work with Oracle directly via TCP/IP without involving Oracle Client.

Wide Coverage of Oracle Features
ODAC supports a wide range of Oracle-specific features, such as:

DML Arrays
REF cursors
Objects
Packages
Direct Path Loading
Alerts
Pipes
Change notifications
Advanced Queuing
Transparent Application Failover
and more...

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, Linux, macOS, iOS, Android, and FreeBSD for both x86 and x64 platforms. ODAC also provides support for the FireMonkey application development platform, which allows you to develop visually spectacular high-performance desktop and mobile native applications.

Secure connection
You can use SecureBridge components with data access components to embed an SSL, SSH, or HTTP/HTTPS clients into your application to establish a secure connection to the server.

Direct Mode
Allows your application to work with Oracle directly via TCP/IP without involving Oracle Client, thus significantly facilitating deployment and configuration of your applications.

Mobile Development
Develompent for iOS and Android mobile devices using ODAC becomes still easier, as ODAC allows your mobile applications to work with Oracle database as simply as desktop applications do.

DB Compatibility
Our product supports Oracle servers 19c, 18c, 12c, 11g, 10g, 9i, 8i, 8.0, including Oracle Express Edition 11g and 10g.

IDE Compatibility
Our product is compatible with the latest IDE versions and editions including Community Edition: Embarcadero RAD Studio 10.4 Sydney, Delphi 10.4 Sydney, C++ Builder 10.4 Sydney, Lazarus (and FPC). It is also compatible with the previous IDE versions since Delphi 6 and C++Builder 6.

Data Type Mapping
If you want to make custom correspondence between Oracle and Delphi data types, you can use a simple and flexible Data Type Mapping engine provided by ODAC.

Development Platforms
All major GUI frameworks supported: develop VCL applications for Windows or cross-platform FMX applications in Delphi, as well as LCL applications for Windows, macoS, or Linux in Lazarus.

Performance
All our components and libraries are designed to help you write high-performance, lightweight data access layers, therefore they use advanced data access algorithms and techniques of optimization.

Monitoring
Use our freeware dbMonitor tool to monitor and analyze all the DB calls made by your application using ODAC. dbMonitor performs per­component tracing of SQL statement execution, commits, rollbacks, etc.
