The aim of this project is to simulate a proper systems design, will need to make the necessary assumptionsto identify the design requirements



12:Details about the design problem as understood by the design team



Scope



Identifying stakeholders



Identifying key functional and non-functional requirements



Identifying an estimate of the project



Identifying a time schedule for the project



13. Constraints and limitations on the design



14. Assumptions made



f. Designing the software systems using various types of models as follows: An entity relationship diagram



g. A matching class diagram



h. A complete set of use case diagrams



i. Activity diagrams for use cases related to establishing new projects



j. System sequence diagrams for the diagrams in d.



Each Model should be introduced and point out the aim of the model and how you design it. Include a brief explanation and description for each model.

Consider the following snippets of code. Then, identify and describe the sorting algorithm used. num scores[5] = 90,85,65,95,75 sort() x = 1 while x < SIZE temp = scores[x] y = x – 1 while y >= 0 AND scores[y]>temp scores[y+1] = scores[y] y = y – 1 endwhile scores[y+1] = temp


Write the code solution using an explicit cursor with a simple Loop. Make sure to use your own variables.


Write a PL/SQL code to find the sum of digits of even digits from a number fetched from a table using implicit cursors and check if the sum is prime number or not.


Suppose you are given a transaction:



read(A);



A:= A - 150;



write(A);



read(B);



B:= B + 150;



Write (B).



Now, describe A-C-I-D properties for the above transaction.

Consider the functional dependency of relation R (M, N, R, P)

F = {M→NR, N→R, M→N, MN→RP }

Compute the canonical cover Fc of F
