Do not worry about this, even if you are, com can also easily deal with ADO without understanding it, because it is very easy to use, and even easier to use than the ODBC APIs, Dao, and rdo you used in the past.

and ADO are two data access methods. 2. The history of data access methods below briefly review several stages of Microsoft's data access methods. ODBC-(Open Database Connectivity) is the first data access technology to access different relational databases using SQL. ODBC applications can be used to manipulate different databases through a single command. What developers need to do is to add the corresponding ODBC driver to different applications. Unlike ODBC, Dao-(data access objects) is

Abstract: This article describes how to use ADO objects to dynamically create databases and data tables in VB Programs. These methods are of great practical value in the development of VB Database applications, and can improve the flexibility of database programs.Key words: database, data table, ADO, ADOX1: Question proposalIn Visual Basic, there are three common Data Access interfaces: Database Access Object (DAO, Data Access Object) and Remote database Object (

, DBASEIII PLUS, Dbaseiv, foxbase+, and Arago. Xbase originally originated from a mainframe-used DBMS called Jpldis (Jet-driven Lab database management and Information Retrieval system). This DBMS was successfully developed by the American Jeb Long in 1972. So far, developers and programmers around the world have written tens of millions of lines of xbase code. Dating back to the late 80, Foxbase was the dBASE clone system. As long as DBASEIII can do

Microsoft's. NET Architecture. Known. NET system is different from COM system, ADO. NET interface is completely different from the ADO and OLE DB interfaces, which means that ado.net and ADO are two ways of accessing data. -------------------------------------------------------------------------------- 2. History of data access methods Here's a quick look at several stages of Microsoft's data access approach. odbc– (Open Database connectivity) is the first data access technology that uses SQL

I. History of data access MethodsGeneric data access model: odbc– (Open Database Connectivity) is an underlying access technology that establishes a set of specifications and provides a set of standard APIs (application programming interfaces) for database access. OLE db– as more and more data is stored in a non-relational format, a new architecture is needed to provide a seamless connection between this application and the data source, and the OLE DB based on COM (Component Object Model) comes

ever contacted database programming, they may be familiar with ODBC and RDO. Open Database Connectivity (ODBC) is an application programming interface (API) that allows access to relational databases, such as Access and SQL Server. Because it is an API, many programmers, especially in the Visual Basic field, find it very complex to use. A remote Data Object (RDO) is an ActiveX object located on the upper l

In C ++ Builder5, use ADO database programming-general Linux technology-Linux programming and kernel information. The following is a detailed description. This article introduces how to use the new ADO control in the C ++ Builder 5 environment, and provides a simple example. I. ADO Overview ADO (Active Data Object) is a database model of Microsoft Based on ole db. It implements a series of COM interfaces and implements Data access in a broad sense through Data Provider and Data Consumer. The A

. UDA (universaldataaccess)This is a general data access policy provided by Microsoft. Including ado, oledb, and ODBC. It not only provides database access capabilities, but also supports other data storage technologies, such as directory services, Excel table data, and exchange server data.Ii. ODBC (opendatabaseconnectivity)This is currently recognized as the best data access technology. The ODBC structure contains a common SQL-based API that uses the corresponding driver to develop specific da

Using ADO in VC to perform database operations ADO is a programming interface at the application layer. It accesses data through the COM interface provided by ole db. It is suitable for various client/server application systems and web-based applications, especially in some scripting languages, accessing database operations is the main advantage of ADO. ADO is a set of object hierarchies established with automation technology. It is more flexible than other object models such as Dao (Data Acces

ODBC is an underlying access technology. Therefore, ODBC APIs can be used by customer applications to set and control databases from the underlying layer to complete functions that cannot be completed by advanced database technologies; however, ODBC can only be used for relational databases, making it difficult to Use ODBC to access object databases and other non-relational databases. Dao provides a mechanism for creating and manipulating databases through program code. The biggest feature is th
