Connection to Oracle Database from Delphi, C++Builder, and Lazarus

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 possibilities of connection to Oracle through native Oracle data access and direct Oracle access 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 ODAC with SecureBridge components to embed an SSL, SSH, or HTTP/HTTPS protocols into your application developed in Delphi, C++Builder, Lazarus, and Free Pascal for establishing a secure Oracle database connection.

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

Development 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.

Database Compatibility

Our product supports Oracle servers 23c, 21с, 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 12 Athens, Delphi 12 Athens, C++ Builder 12 Athens, 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.
