Open data connection is to solve data sharing among heterogeneous databases generated.
You become WOSA (WINDOWS Open Systems Architecture) of the main part and provide a unified interface allows applications and SQL data access standard data access to different DBMS management of heterogeneous database access is based on a database WINDOWS environment interface standard ODBC access direct application to support the DBMS manipulate the data, eliminating the DB is changed with the change. DB using ODBC can access files on all types of computers, such as Excel tables can even access and asc‖ data files, such non-database object.
Database variable naming only in English, English capitalized (if not English, Pinyin and Hanyu Pinyin first letter (uppercase))
