Chapter 20. Using ODBC Database Source Names (DSN) ODBC, short for Open Database Connectivity, is a standard software API method for using relational database management systems (RDBMS). The goal of ODBC is to allow SQL (Structured Query Language) queries to take place on the database independent of the programming language used. An ODBC implementation consists of three (3) components: 1. The Application (in this case, the IWS application) 2. A Core ODBC Library 3. A database Driver The Core ODBC library is provided by the Operating System (e.g. Windows XP) and interprets commands sent by the application to the database (through the Driver). The Driver is specific to a database, and only needs to know how to attach to the Core ODBC library. Almost every database in existence can be interfaced via ODBC. Microsoft now ships ODBC with every version of Windows (except Windows CE which does not support ODBC). In order to use this capability, you must use Microsoft .NET Framework 1.1 or higher. Note: • The Microsoft .NET Framework 2.0 is automatically installed with IWS v.6.1 Service Pack 3 The connection between the Application and the Database starts by defining a DSN, or Database Source Name. This is structure to define the connection to the Database, including the protocol, host, port and database. This connection is defined in detail at the Operating System Services level, not at the Application (or VBScript) level. Note: • A DSN (e.g. System DSN) must be specified by the Operating System To configure a DSN (e.g. Windows XP Pro), you click on the Start button, select Control Panel, and then Administrative Tools. Next, click on the Data Sources icon. This opens the ODBC Data Source Administrator dialog box. Note that there are three different type of DSN’s: • System DSN In general, you should use a System DSN. This type of DSN is not dedicated to a specific user, and is available to all users on the local computer. The data source is local to the computer. • File DSN This type of DSN can be shared among all users who have the same driver(s) installed. The data source is not user-dedicated and need not be local to the computer. • User DSN This type of DSN is only available to the current user and the data source is local to the computer.
