| IBM originally created SQL for use between databases located on mainframe computers and the users on client machines. The users were connected to the mainframes via a local area network (LAN). SQL was adopted as the standard language of communication between databases and users. An intranet is basically a small Internet. The main difference is that an intranet is for a single organization's use, whereas the Internet is accessible to the general public. The user (client) interface in an intranet remains the same as that in a client/server environment. SQL requests are routed through the Web server and languages (such as HTML) before being directed to the database for evaluation. An intranet is primarily used for inner-corporate applications, documents, forms, Web pages, and email. | | Database security is much more stable than security on the Internet. Always be sure to use the security features available to you through your database server. | |
