Description of Method Solution

This stage is the most important stage ofsystem development life cycle. Thisnew system is designed in such a way that the programmer can write the

programming codes for the new system, with the drawings of the data capture

and data output methods are given. This stage also includes the database

design. The hierarchy is also included in this stage. So overall, this stage is

meant for the programmer who will write the programs to realize a fully

functioning system.

Tasks which will be involved for the success of this stage are:

1. Table and its structure along with thevalidation rules.

2. Description of the validation rules.

3. Layout of input/output forms.

4.

Navigation hierarchy of input/output forms.5. Description of routine tasks.

6. Algorithm.

7. Flowcharts.

%! Description of routine tasks:

"n this new system the first this task is to assign each spare part aspecial identification number called the part number;. 2 new number would

be generated the purchase of each new spare part, these number would be

generated in series to avoid inconsistency. The part number would be printed

and pasted on the bo$ of each spare part before it is placed in the shelf of the

warehouse.

1) ach and every year a new model of each car is launched, so new

spare parts are needed which did not e$ist in the shop before, in order

to do that a purchase order is placed, upon the arrival of the stock thepart numbers are generated along with the location and are then printed

and stuck o the bo$ of the spare part, then they are entered in the Stock

Master File 7through form no#%8. This process is known asInsert
