ANALYSIS AND DESIGN
Emphatically, the methods needed in
collecting data with regard to the design of the design of the purposed system
(i) Personal interview method
(ii) Examination of record and procedure
manual of the organization
During this method personal contact
was made with some knowledgeable and experienced people in the department in
order to give room for the collection of satisfactory data that would lead to
the successful design of the proposed system.
OF RECORDS AND PROCEDURE MANUAL
If existing procedure are already
well documented, a procedure manuals can provide a ready-made source of
information on the way procedure should be carried out. However, it is
important to realize that the procedure details in the procedure manuals may
not accord with actually happens. The examination of current records and the
tracing of a particular transaction from input to the production of required
output can be a method by which the system analyses may be discovers how
closely the set procedures actually followed.
method of collecting data involves the following
method of investigation through the skill of interviewing are not ready
acquired the interviewer needs to know how to gain the confidence of the
interviewee and ensures that the person feels that the information which is
given will be of value in the design of the proposed system.
involves the direct contact of the interviewer with the interviewee the
question must be ambiguous in order to obtain the required information.
Opinions are as
valuable as they will reveal the strength and weakness of the university.
are useful when only a small amount of information is required form a large
number of people. This process involves the printing of questions on the
required area of investigation. To provide accurate response questions need to
be unambiguous and precise. Questionnaire can be useful for gathering
statistical information such as student’s name, course, matric number, contact
no, department and so on. This help in marking easy to know the students
It is most important to observe a
produce in action so that irregularities and exceptional procedure are notice:
Observation should be carried out with care and staff under observation should
be made fully aware of the purpose to void suspicious on misinterpretation.
ANALYSIS OF THE PROPOSED SYSTEM
Data is capture and delivered to the
clerk for the proper entry into the system. The clerk or secretary (user) is
required to entry data into the appropriate field as specified by the designer.
The keyboard is used a sthe input
device, The user of the proposed system is expected to fix data into the
appropriate field name in accordance with the specification by the designer.
System controls minimize or eliminate errors before, during and after
processing so that the data entered and the information produced are complete
and accurate control system also minimize the possibility of computer fraud.
There are four
types of control:
Entered: Data are check for accuracy when entered into the system.
2. Processing Controls: System analysis
and programmers use a variety of techniques to validate that processing is
complete and accurate.
3. Procedural Control: People oriented
procedures are build into the system form control purposes.
4. Output Control: The accuracy of output
is verified before it is sent to the user.
There are eight data base files used
in this system design, these are:-
(i) PAYMENT Dbf:- This handles the process
of payment of the student
(ii) PROJECT Dbf:- This handles student
registration for a particular course
(iii) PROJ1 Dbf:- This take care of the
information about the parents of the student
and next of kin
(iv) PROJ3 Dbf:- It takes care of student name
and the information about the two
(v) PROJ4 Dbf:- It takes care of student
past academic records before the admission
(vi) PROJECT Dbf:- It handles the current
student academic records
(vii) PROJ1.Dbf:- It takes care of the student
(viii) PROJ2.Dbf:- It handles the production of individual
result, the structure of the
