Dynamic sites characterized as more sophisticated sites where static allow modernization and change the contents of its pages through the management of the site at any time, and quite easily.
Design requires the use of dynamically several other Techniques to assist in addition to the language HTML pages, as well as linking the site to a database.
Web page design techniques dynamic:
• active server pages ASP:
A technique developed by Microsoft and incorporated in its own web server (IIS) to create web pages and applications of a strong and dynamic depending on the databases or user input.
Can contain ASP file to HTML by one of the scripting languages Scripting language such as VB script, Jscript and others.
ASP pages dealt by the server, or the so-called Server side language, and even be addressed, it will be installed by programs called dynamic link library b ASP.DLL, when the user requests a page asp extension. The web server is addressing ASP orders on this page, and sends the result to HTML page display in the web browser on the user’s computer this method provides a degree of security and confidentiality for these pages and therefore preserves human programmer copies since the user can not see the orders ASP when viewing source page, but finds HTML output is treated This allows presentation ASP pages to all Web browsers do not require the presence of any other programs on the user’s computer.
ASP allows access to databases and recover or update their information, where ASP pages can be linked to all kinds of databases, whether Access Access, SQL server, Oracle and others, through organisms ADO installed with the use of language and SQL to access records databases. ASP characterized as independent of the language, which does not depend on the engine ASP certain language can be written in languages such as ASP pages VBscript (the default language for ASP), Perlscript, Jscript.
ASP also easily distinguished programming where any person can have a simple experience in the area of computer use to perform the functions of software.
• Language HTML:
It Markup language texts Hyperlinks are used to create Web pages, does not need an interpreter own Compiler, which is not linked to a particular operating system because it is their interpretation and implementation instructions directly by the web browser regardless of the operating system to the user, as is HTML language very simple and easy to understand and learning can be of use reached a series of pages and through making connections among them.
• Active X Data objects ADO:
It is access to technical data used by the ASP to reach the OLE DB and other data sources.
ADO has been developed by Microsoft Corporation is a Component contains many organisms Objects facilitate contact databases and conduct various operations, and the following figure illustrates the contact database through ADO objects.
• databases Data Bases:
Is a set of integrated data, stored in the form of tables. And characterized by the use of the data to design web pages that the process of maintaining the databases are easier to maintain web pages and databases to facilitate the search for information.
There are many ways to organize data within the database and the main roads of the so-called database management system, a DBMS programs enable the user to store and retrieve data and processing to get them useful information. Access Access is a database management programs (which was used in this project), the database language of a particular language SQL queries vehicle.
SQL is the language used by applications to send orders to relational databases and SQL are used to control actually destruction in the database through the addition and deletion and modernization, and to petition.
