access to relational databases, which are two-dimensional data databases. However, with the development of technology, we obviously need to face not only relational databases, but also non-relational and hierarchical row data that cannot be accessed using SQL, includes data in the mail system, text on the Web, directory services, and other forms. Therefore, from the data source perspective, the relationship between ole

Evolution HistoryThey are gradually appearing in the order of this time, prehistoric->odbc->oledb->ado->ado.net.Look at the MDAC definition on the wiki: "Microsoft Data Access Components (MDAC) is the application development interface that Microsoft has developed specifically for the data access function, as a unified data access for

not only the structured Problem language (SQL) capability of the Microsoft-funded standard data Interface Open Database Connectivity (ODBC), but also the pathways for other non-SQL data types. As a design of Microsoft's Component Object Model (COM), OLE DB is a set of methods for reading and writing data (which in the past may be called a channel). The objects in the old

This month, the company acquired a small company. The database of this small company uses the 32-bit SQL2000, which has been in use for a long time and the system is relatively stable. In line with the principle of cost saving, the company retains the original company's management system, but requires that important data be uploaded to the company's 64-bit sql2005 database every day, this simple job is done by a person like Gao Sheng. I thought this was a simple task, but when I built the linkse

obviously we need to face not only the relational database, but also the non-relational row and hierarchy row data that cannot be accessed with SQL, including the data in the mail system, the text on the Web, the directory service and so on. Therefore, the relationship between Ole DB and ODBC from the point of view of the data source is as follows:based on COM standardsODBC is an API-based implementation,

It is noteworthy that OLE DB compatibility with ODBC allows OLE DB to access existing ODBC data sources. The advantages are obvious because ODBC is more commonly used relative to OLE DB, so you can get more ODBC drivers than

When you need to operate a database, ole db is always considered to be the most efficient but difficult method. However, in my recent use of ole db, the efficiency of ole db is high, but it is not difficult at all. I am afraid it
