The application uses ODBC functions through an ODBC driver manager with which it is linked, and the driver passes the query to the DBMS. An ODBC driver can be thought of as analogous to a printer driver or other driver, providing a standard set of functions for the application to use, and implementing DBMS-specific functionality.
BDE's application program interface provides direct C and C++ optimized access to the database engine, as well as BDE's built-in drivers for dBASE, Paradox, FoxPro, Access, and text databases. The core database engine files consist of a set of DLLs that are fully re-entrant and thread-safe. Included with BDE are a set of supplemental tools and ...
The driver that Microsoft provides in MDAC is called the SQL Server ODBC Driver (SQLODBC), and (as the name implies) is designed for Microsoft's SQL Server. It supports SQL Server v6.5 and upwards. [3] ODBC allows programs to use SQL requests that will access databases without having to know the proprietary interfaces to the databases. It ...
For VB [Visual Basic] 3.0 they basically had to tear it out of Access and graft it onto VB. That's why they've had all those Jet/ODBC problems in VB 3.0." Jet became more componentized when Access 2.0 was released because the Access ODBC developers used parts of the Jet code to produce the ODBC driver.
The unixODBC project was first started in the early months of 1999 (by Peter Harvey) and was created as at that time the developers of iODBC (another open source ODBC implementation) were not then willing to LGPL the code, expand the API to include the current ODBC 3 API specification, and did not consider the addition of GUI based configuration tools worthwhile. iODBC now has these parts ...
As well as DAO and ADO, developers can also use OLE DB and ODBC for developing native C/C++ programs for Access. [45] For ADPs and the direct manipulation of SQL Server data, ADO is required. DAO is most appropriate for managing data in Access/Jet databases, and the only way to manipulate the complex field types in ACCDB tables.
Updates has to be done with other in the IDE integrated components as the "DatasetProvider", which assembles automatically appropriate Update-Statements ( in SQL ). Embarcadero supplies drivers for many databases, including Oracle, Firebird, InterBase, IBM Db2, Informix, SQL Server, MySQL and ODBC. Additional drivers are available from third ...
OLE DB providers are analogous to ODBC drivers, JDBC drivers, and ADO.NET data providers. OLE DB providers can be created to access such simple data stores as a text file and spreadsheet, through to such complex databases as Oracle , Microsoft SQL Server , Sybase ASE , and many others.
