After the crisis the business of IT experience a slight increase in recruitment according to a study. This increase is totally understandable because we use almost all the computer at work or at home. It is for IT professionals to ensure that computers and the network they are connected are functioning properly. However, we can observe a decrease in income between graduates and older (25% for network administrators, -15% for systems engineers, 10% for developers and ultimately -5% for network engineers).

We can divide the business of IT into three parts:

Administrators database:
Their role is to create databases of both flexible and robust to be able to store any data type. They must also ensure that the Data File Recovery is secure so that nobody can infiltrate and retrieve information private.

IT developers are those involved in developing the application following a detailed specification which lists the user requirements. They can work in a software house or directly on behalf of large companies supervised by project manager. Developers use different programming languages ​​to develop software and applications. Among the wide range of languages ​​include: c / c + + java,. Net, PHP.
