Frequently used terms
This section lists frequently used terms. An application server is software that helps a web server process web pages containing server-side scripts or tags. When such a page is requested from the server, the web server hands the page off to the application server for processing before sending the page to the browser. For more information, see How a web application works. Common application servers include ColdFusion, JRun Server, the Microsoft .NET Framework, IBM WebSphere, and Apache Tomcat. A database is a collection of data stored in tables. Each row of a table constitutes one data record and each column constitutes a field in the record, as follows.
A database driver is software that acts as an interpreter between a
web application and a database. Data in a database is stored in a proprietary
format. A database driver lets the web application read and manipulate data
that would otherwise be undecipherable. A database management system (DBMS,
or database system) is software used to create and manipulate databases. Common
database systems include Microsoft Access, Oracle 9i, and MySQL. A database
query is the operation that extracts a recordset from a database. A query consists
of search criteria expressed in a database language called SQL. For example,
the query can specify that only certain columns or only certain records be included
in the recordset. A dynamic page is a web page customized at runtime by an application
server before the page is sent to a browser. For more information, see How a
web application works. A recordset is a subset of data extracted from one or
more tables in a database, A relational database is a database containing more
than one table, and the tables share data. The following database is relational
because two tables share the DepartmentID column
A server technology is the technology that an application server uses to modify dynamic pages at runtime.
The MX development environment supports the following server technologies:
ColdFusion
Microsoft ASP.NET
Microsoft Active Server Pages (ASP)
Sun JavaServer Pages (JSP)
PHP Hypertext Preprocessor (PHP)
You can also use ’s coding environment to develop pages for any other server technology not listed above.
A static page is a web page that is not modified at runtime by an application server before the page is sent to a browser. For more information, see Processing regular web pages.
A web application is a website that contains pages stored on a web server with partly or entirely undetermined content. The final content of these pages is determined only when the user requests a page from the web server. Because the final content of the page varies from request to request based on the user’s actions, this kind of page is called a dynamic page.
A web server is software that serves web pages in response to requests from web browsers. A page request is generated when a user clicks a link on a web page open in the browser, chooses a bookmark in the browser, or enters a URL in a browser’s Address text box and clicks Go.
Popular web servers include Microsoft Internet Information Server, Microsoft Personal Web Server, Apache HTTP Server, Netscape Enterprise Server, and iPlanet Web Server.
