In a client/server environment, processing tasks are divided between an application on a client computer system, and a database on a server. The client and the server are linked by a network. The client makes requests for services provided by the server. These services may include querying a database, printing a document, or backing up data. The client performs operations on the data that is returned by the server and interacts with the user.
There are several advantages to a client/server environment. Instead of sending the whole database back and forth across the network, network traffic is limited to queries from the client to the server and responses from the server to the client. Also, the data on the server can be accessed from multiple client applications. The server is responsible for maintaining data integrity and security at a centralized location.
Important Before you can use Microsoft Access with a server, you must install the appropriate Open Database Connectivity (ODBC) drivers. If you clicked Typical when you installed Microsoft Access, you don’t have these drivers installed. For information on how to install drivers, search the Help index for “installing drivers.”
Additionally, you must use the ODBC Data Source Administrator to set up an ODBC data source for each remote database to which you want to connect. To start the ODBC Data Source Administrator, double-click 32bit ODBC in Windows Control Panel.
Note Some database server documentation refers to records as rows and to fields as columns. This chapter uses the terms records and fields.
