Question
analysis stage and data analysis
Hi Experts,
I have been given an a task to provide analysis of a company and then to do data anlysis. It is following this that a new system can be designed.
I have gathered requirements and the functionality of the proposed system.
Please can someone tell me a simple definition of data analysis and what it involves. My understanding of it is to analyse the functions and tasks of users and provide a scope of the system, ie. objects, typical range and scope of variables (i.e. Employee number must be 5 digits). Am I on the right lines here?
Any guidleines to follow on this would be a massive help to me.
Thankyou for your assistance.
