Q.1.1: The two programming models that could be considered for the development of the application are procedural programming and object-oriented programming.
- Procedural programming is a programming paradigm that involves breaking the program down into smaller, structured procedures or functions that are executed in a sequential manner. In the case of the application for sports administrators, procedural programming could be used to create separate procedures for tasks such as managing player profiles, scheduling matches, and calculating salaries.
Example: In procedural programming, you could have a separate procedure for each task, such as "managePlayerProfiles", "scheduleMatches", and "calculateSalaries". Each procedure would have a specific set of instructions to perform its respective task.
- Object-oriented programming, on the other hand, is a programming paradigm that focuses on creating objects, which are instances of classes that encapsulate data and behavior. In the case of the application for sports administrators, object-oriented programming could be used to create classes for entities such as players, matches, and teams, with their own properties and methods.
Example: In object-oriented programming, you could have a Player class with properties like "name", "position", and "matchesPlayed", and methods like "applyForLeave" and "calculateSalary".
Q.1.2: To ensure that the application functions as intended before delivering it to the client, several testing and quality assurance measures can be taken. These include:
- Unit testing: Individual components or functions of the application can be tested in isolation to ensure they function correctly.
- Integration testing: The application can be tested as a whole to verify that different components work together seamlessly.
- Functional testing: Test scenarios can be created to verify that the application meets the required functionalities specified by the client.
- User acceptance testing: The application can be tested by users or representatives of the client to ensure it meets their expectations and requirements.
- Code reviews: The code can be reviewed by other developers to identify any bugs, errors, or areas for improvement.
- Performance testing: The application can be tested under various load conditions to ensure it performs efficiently and meets performance requirements.
Q.1.3: One tool that can be used to plan the logic for the application is a flowchart. A flowchart is a graphical representation of the steps or flow of a process or program. It can visually outline the logical sequence of operations and decision points in the application.
Q.1.4.1: Example of a variable declaration to store the number of leave days applied for by a team player:
int leaveDays;
Q.1.4.2: Mathematical expression to determine a player's salary based on the number of matches played in a given month:
salary = Matches * 75000;
Q.1.4.3: Example of a hierarchy chart indicating the modules forming part of the application:
- login( )
- schedulePlayer( )
- approveLeave( )
- determineSalary( )
Q.1.4.4: To write the statement "Calculate the player's salary" as a comment in the application, you can use the "//" or "/* ... */" syntax to indicate that it is a comment.
Example:
// Calculate the player's salary
Consider the following short scenario, then answer all of the questions based on this scenario:
South Africa has a national soccer, cricket and rugby team representing the country in a variety of
tournaments every year. The sports administrators need an application that will assist them in the
administration of the various sports teams.
Q.1.1 Identify and differentiate between the two programming models or paradigms
that will be considered for the development effort. Substantiate your answer with
examples related to the development of the application required by the sports
administrators.
