3. You will be shown the screen above, as in the above screen enable the connection type that suites your environment. If you are not sure then you need to consult a network or database administrator and close this application immediately. 4. In the examples contained in this application note the TCP/IP connection is used to the standard SQL Server Port 1433. 5. Close the SVRNETCN.EXE application. Database Overview The ability to connect from remote applications that require user data to be updated in real time allows for many possible interfaces and configurations. In most cases the data connectivity function will allow applications such as an external photo id issuing station, employee database or custom applications to connect to the protégé system. This functionality may be used permanently or only at the initial stages of installation to get all users within a company in to the database in real time. Figure 1 - Basic Database Connection In the above example a remote database is being used to store user data, this database is connected to the protégé external user table allowing data for the access control system to be updated in real time. 4 AN-016 Protégé Server ODBC Database Connectivity
In most cases this is the typical use of the database connectivity, the database can be an employee or administration database maintained by a larger company wide application and example of this is SAP, PeopleSoft, DataCard Image Works or similar Photo ID, Company or employee management applications. For an example of a connection using ODBC and Microsoft Access complete with example forms and reports refer to the Example Application Section on Page 13. Figure 2 - Advanced Database Connection In the above example a remote application is being used for Photo-ID and is using data from the remote database to attach additional user information (Photo, Issue Number). This database then uses a trigger or internal update method to send the information to the Protégé System when the data changes. The example is further complicated by the external database being modified and maintained by a distributed data entry application used for the initial entry and data processing portion of the users being added to the system. It is important to note that in the advanced connection the remote database is the primary database and the Protégé System external user table is a secondary portion being updated from data within the remote database. To import users into the Protégé System Management Suite from an external file use the Import User wizard available from the File Menu in the Protégé System Management Application. Many formats are already included and user definable formats available, for more information consult the Protégé System Management Suite Help File. To import users from an existing database use an appropriate update query or code to write the users in to the External Database Table. This will mean the protégé system controllers will be updated at the same time. It is recommended to batch load users in smaller groups. AN-015 Protégé Server ODBC Database Connectivity 5
