UniDirect .NET是一款數(shù)據(jù)發(fā)生器控件，它用于為Microsoft .NET Framework.建立針對不同類型的數(shù)據(jù)庫的常規(guī)連接。它支持常規(guī)的主流的數(shù)據(jù)庫服務類型，比如Microsoft SQL Server, Oracle, DB2, MySQL, PostgreSQL和其他通過 OLE DB和ODBC的數(shù)據(jù)庫.
特征綜述 About Feature
UniDirect .NET is based on ADO.NET technology and can be used in the same way as the SQL Server .NET Data Provider. The main feature of UniDirect .NET is an access to multiple database servers at the same code. With UniDirect .NET it is possible to avoid writing conditional code for different providers or using ADO.NET interfaces directly. UniDirect .NET implements full support of design-time development and integration with IDE, which allows to reduce development time greatly.
UniDirect .NET doesn't implement database specific access layer for all databases, it uses native ADO.NET providers and depends on their functionality. The Professional Edition of UniDirect .NET includes bundled data providers for Oracle, MySQL and PostgreSQL (see diagram below). For all other servers you need a native data provider.
UniDirect .NET provides functionality for connecting to a database, executing commands, and retrieving results. These results can be processed directly or placed in an ADO.NET DataSet for further processing in 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 in the DataSet can then be reconciled with the database.
The following diagram illustrates UniDirect .NET architecture. The green area represents some of UniDirect .NET components. The lime area unites bundled providers in the Professional Edition. The rest of the diagram objects represent data access elements inside and outside of the .NET Framework.
