dotConnect for Oracle is a data provider to direct access to Oracle database server for the Microsoft .NET Framework and .NET Compact Framework. It is completely based on ActiveX Data Objects for the .NET Framework (ADO.NET) technology. ADO.NET provides a rich set of components for creating distributed, data-sharing applications. It is an integral part of the .NET Framework, providing access to relational data, XML, and application data. dotConnect for Oracle data provider can be used in the same way as the SQL Server .NET or the OLE DB .NET Data Provider. dotConnect for Oracle can access Oracle server using Oracle Call Interface (OCI) or through TCP/IP directly.

OCI is low-level native application programming interface to access to Oracle database. Using OCI allows to create lightweight and fast applications working with Oracle. However, this way of communicating with Oracle server requires Oracle client software installed, which may be undesired or even impossible. For such cases dotConnect for Oracle provides an ability to use Direct mode. In Direct mode the provider connects without Oracle client and requires only TCP/IP protocol that allows to build really thin database applications.

dotConnect for Oracle provides functionality for connecting to Oracle database, executing commands, and retrieving results. Those results can be processed directly, or placed in an ADO.NET DataSet for further processing while in a disconnected state. While in the DataSet, data can be exposed to the user, combined with other data from multiple sources, or passed remotely between tiers. Any processing performed on the data while in the DataSet can then be reconciled to Oracle database. dotConnect for Oracle data provider is designed to be lightweight. It consists of a minimal layer between Oracle database and your code. This extends functionality without sacrificing performance.
