A Pay per click advertisement is where the advertiser pays their host (e.g. search engines) only when their advertisement has been clicked. The advertisements are displayed through key words or key phrases.

MySQL, the most popular Open Source SQL database management system.

MySQL is a relational database management system.
A relational database stores data in separate tables rather than putting all the data in one big storeroom. This adds speed and flexibility. The SQL part of “MySQL” stands for “Structured Query Language.” SQL is the most common standardized language used to access databases.

Its open source which means that it is free for anyone to use and modify the software.

MySQL Server offers a rich and useful set of functions. Its connectivity, speed, and security make MySQL Server highly suited for accessing databases on the Internet.

This can be useful in development of online business. Consumers and web browsers can find it easier to search for products you are selling and which ones you have in stock if there is a database. MYSQL enables that.

MySQL Server works in client/server or embedded systems.

The MySQL Database Software is a client/server system that consists of a multi-threaded SQL server that supports different backends, several different client programs and libraries, administrative tools, and a wide range of application programming interfaces (APIs).
Therefore this is very advantageous when it comes to compatibility issues.
So if your website runs on different platforms you do not have to worry about compatibility issues.
Most applications and programs can support SQL.

MySQL is a database server program and as such is installed on one machine, but can 'serve' the database to a variety of locations.

To see how it works visit the website

There is a diagram and an explanation as to how exactly it works.

When setting-up an online business it is important to have knowledge of the PHP language, since it will be required when making the website for the online business.

There are two different determinants that can be used in setting the prices:

1) Flat rate PPC:
Advertisers and host agree upon a fixed price per click

2) Bid based PPC:
This is where the advertiser gives the maximim price they are willing to pay for a given ad spot.

Sajni said...

Gantt chart and Project management tools are related to the case study as the hosts of online business can track its progress. It can also increase specializtion or delegation and as hosts dont have to be in one site, it can help communication between hosts and provide better service.

Structured Query Langauge is cross between a math-like language and an English-like language that allows us to ask a database questions or tell it do do things. There is a structure to this language: it uses English phrases to define an action, but uses math-like symbols to make comparisons.

@ Immi
how is bid based payment pay-per-click if the advertisors are paying the hosts a fixed rate in advance?

Cascading Style Sheets (CSS) is a style sheet language used to describe the presentation semantics (the look and formatting) of a document written in a markup language. Its most common application is to style web pages written in HTML and XHTML.
The CSS is like the master slide in Microsoft power point. This is useful whe it comes to designing web pages as you don’t have to design each page individually you can make a standardized format the applies to all the web pages as seen in the diagram in the link below http://www.html.net/tutorials/css/lesson2.php
