LAB Course Solved

Section A: Object Oriented Analysis and Design 
Question 1: As online commerce is increasing, many organizations are setting up online digital payment system which work as follows: 
(i) A costumer does shopping on any shopping site with a credit card or a debit card. A credit card and debit card is issued to any person after verification of all details by a bank such as identity card and the salary statement for the last six months. 
(ii) Purchasing detail goes through a payment gateway which encrypts the data to keep it private  and send it to the payment processor  
(iii) The payment processor sends a request to the costumer’s issuing bank to check whether they have enough credit to pay for the purchased items
(iv) The issuing bank responds with a yes (a approval) or no (a denial)   
(v) The payment processor sends the answer back to the costumer’s merchant bank to credit the account in the name of a costumer.  
Do the following tasks: (1) Draw Use Case diagram (2) Define all classes and the  class diagram     (3) Draw a simple object model  (4) Draw a state transition diagram       
Section B: MCS-34: Software Engineering 
Question 2: For the digital payment problem discussed in a section A do the following tasks: 
(1) Develop SRS  (2) Draw Data Flow Diagrams (Level 0, Level1) (3) Draw an E-R diagram and its related normalized tables.
Section C: MCS-035: Accountancy and financial Management

Array

Image
  An array is a collection of similar data elements stored at contiguous memory locations. It is the simplest data structure where each data element can be accessed directly by only using its index number. For instance, if we want to store the marks scored by a student in 5 subjects, then there’s no need to define individual variables for each subject. Rather, we can define an array which will store the data elements at contiguous memory locations. · array  marks[5]  defines the marks scored by a student in 5 different subjects where each subject marks are located at a particular location in the array i.e.  marks[0]  denotes the marks scored in first subject,  marks[1]  denotes the marks scored in 2nd subject and so on.

  STACKS in Data Structure A stack is  an abstract data type that holds an ordered, linear sequence of items . In contrast to a queue, a stack is a last in, first out (LIFO) structure. A real-life example is a stack of plates: you can only take a plate from the top of the stack, and you can only add a plate to the top of the stack... Click here to Know more

Asymptotic notations

-
  Data Structure The main idea of asymptotic analysis is to have a measure of efficiency of algorithms that doesn’t depend on machine specific constants,  and doesn’t require algorithms to be implemented and time taken by programs to be compared. Asymptotic notations are mathematical tools to represent time complexity of algorithms for asymptotic analysis.  The following 3 asymptotic notations are mostly used to represent time complexity of algorithms. 1) Θ Notation, 2) Big O Notation, 3) Ω Notation.
