Question (a) List and discuss two additional fields that could or should appear on the above table structure.
Question (b) Identify and discuss the serious data redundancy problems exhibited by the file structure shown in the given data sheet.
Explanation / Answer
Answer : two more field that can be added are :
1) Department, it helps in identifying the department to which the particular project belongs hence helps in allocating resources.
2) project manager, this is an existing employee and will be heading the project.
B) in the given structure all the data is contained in one table hence multiple entries are made for a single project for all the employees that are working on that project. If there are 100 employees working on single project than 100 entries for the project are made , this is simply the redundant data and we can get rid of it by normalising the table.
