Oracle Data Access Components (ODAC) vs. Oracle SQL Developer vs. dbExpress Drivers vs. ADO.NET Data Providers Comparison Chart

Oracle Data Access Components (ODAC) are a set of Windows and .NET data access drivers and tools. They include support for .NET data access, Microsoft Visual Studio tools for developing Oracle database applications; and ASP.NET providers. ODAC provides comprehensive client support for advanced Oracle database functionality, including performance, high availability, and security, among other features. It is tightly integrated with Visual Studio to provide a seamless development experience for developers. Oracle Data Provider for .NET is an implementation of Microsoft's ADO.NET interface and provides access to Oracle databases. OLAP Data Manipulation Language (OLAP DML) is used to define and manipulate analytic workspace objects. High performance, a feature-rich mechanism for Microsoft ADO and OLE DB data access to Oracle databases, its usage, and its configuration. Provides introductory, installation, post-installation configuration, and usage information.

dbExpress is a database-independent layer that defines common interface to provide fast access to SQL database servers from Delphi and C++Builder including Community Edition, on Windows and macOS (32-bit and 64-bit) and Linux (64-bit) platforms. For each supported server, dbExpress provides a driver as an independent library that implements the common dbExpress interfaces for processing queries and stored procedures. As data-access layer is thin and simple, dbExpress provides high-performance database connectivity and is easy to deploy. You can use our drivers in the same way as the ones supplied by Embarcadero.
