This is mainly due to the lack of resources, limited operations and economic reasons. However, despite all this, the roles of the different people involved in any typical IT department can easily be defined separately.
The IT director being the head of the department represents the IT in the top management team. Other three categories and/or designations are the people directly involved with workings and infrastructure of the IT of the company.
The database administrator is simply the person managing the central database server of the organization. However there are significant confusions regarding the roles of the system and network administrator(s).
The field of system administration is a broad term used to define the roles and responsibilities of the person who maintains and operate the IT infrastructure of the company as a whole. A system administrator, also known as the 'sysadmin' (Microsoft, 1999), can have a work schedule ranging from a few hours per week to a full time job depending on the size of the organization. A system administrator might not even know the CEO, but he actually acts as the liaison between the technical and the non-technical staff of the organization. Some of the basic duties performed by the system administrator(s) are (Limoncelli & Hogan, 2007);
Install and maintain the user...
