Whatson api for pictures12/8/2023 ![]() An exception to this is that developers who write drivers that directly access file data (such as data in an Xbase file) are required to write a database engine that supports at least minimal SQL functionality. Nor are driver writers expected to implement functionality not found in the underlying database. Thus, application writers should not expect that using ODBC will suddenly transform a simple database into a fully featured relational database engine. It is important to understand that ODBC is designed to expose database capabilities, not supplement them. Microsoft has teamed with Visigenic Software to port these SDKs to the Macintosh and a variety of UNIX platforms. To help application and driver developers, Microsoft offers an ODBC Software Development Kit (SDK) for computers running Windows 95 and later that provides the driver manager, installer DLL, test tools, and sample applications. Furthermore, ODBC drivers and applications exist on the Macintosh® and a variety of UNIX platforms. In fact, the vast majority of ODBC applications and drivers available today are written by companies other than Microsoft. ![]() ![]() A Driver Manager manages communication between applications and drivers.Īlthough Microsoft provides a driver manager for computers running Microsoft Windows® 95 and later, has written several ODBC drivers, and calls ODBC functions from some of its applications, anyone can write ODBC applications and drivers. Applications call the functions in these drivers to access data in a DBMS-independent manner. The functions in the ODBC API are implemented by developers of DBMS-specific drivers. x fully implements both of these specifications - earlier versions of ODBC were based on preliminary versions of these specifications but did not fully implement them - and adds features commonly needed by developers of screen-based database applications, such as scrollable cursors. The ODBC API is based on the CLI specifications from Open Group and ISO/IEC. This API is independent of any one DBMS or operating system although this manual uses C, the ODBC API is language-independent. To many others, it is the answer to all database access problems ever imagined.įirst and foremost, ODBC is a specification for a database API. To the application programmer, it is a library containing data access routines. To the end user, it is an icon in the Microsoft® Windows® Control Panel. Many misconceptions about ODBC exist in the computing world.
