1. Introduction to ADO and ADO. NET
ADO and ADO. NET is both similar and different. They are able to write applications that access and operate data on database servers, and are easy to use, fast, low-memory, and occupy less disk space, supports the creation of client/server-based and Web-based applications. However, ADO uses ole db interfaces and is based on Microsoft's COM technology, while ADO. NET has its own ADO. NET interface and is based on Microsoft's. NET architecture. As we all know, the. NET system is different from the COM system, and the ADO. NET interface is completely different from the ADO and ole db interfaces. That is to say, ADO. NET and ADO are two data access methods.
