Program Plan Intro

Systems development life cycle (SDLC):

The seven phases in SDLC includes:

Planning phase

The planning phase includes creating a goal statement for project.

It defines a high level plan for intended project.

It sets the scope of project.

The project plan denotes a formal, approved document that would manage and control entire project.

A project manager creates a project plan and ensures that project finishes within given deadline and budget.

Analysis Phase

In analysis phase the firm would analyze business requirements.

It refines goals of project into defined operations and functions of intended systems.

The business requirements denote specific business requests made by system so as to successfully complete project.

The requirements management denotes process of managing changes to requirements in business.

A requirements definition document would prioritize all business requirements based on importance order.

Design phase

The design phase creates description for system features and operations.

It includes following items:

Screen layout

Business rules

Process diagrams

Pseudo code

The graphical user interface (GUI) denotes an information system interface.

Development phase

The development phase transforms detailed design documents into actual system.

During this phase, the team defines programming language for development.

A scripting language may provide interactive modules to website.

Object oriented languages may group data into objects.

Testing phase

The testing phase keeps all project modules under testing environment for elimination of bugs and errors.

It verifies that system meets all requirements mentioned in analysis phase.

Bugs denote defects in information system code.

The test conditions denote steps that must be performed and expected result for each step.

Implementation phase

The system is placed into production, detailed documentation is performed.

The users begin actual operations in business within system.

Maintenance phase

The organization performs corrections, changes and up gradations to ensure that system meets requirements.

Corrective maintenance would make system changes to flaws in design, errors in coding or issues in implementation.

Preventive maintenance would make system changes to reduce chances for system failure in future.

Please answer JAVA OOP problem below: Assume you have three data definition classes, Person, Student and Faculty. The Student and Faculty classes extend Person. Given the code snippet below, in Java, complete the method determinePersonTypeCount to print out how many Student and Faculty objects exist within the Person array. You may assume that each object within the Person[] is either referencing a Student or Faculty object. public static void determinePersonTypeCount(Person[] people){ // Place your code here }

Please answer JAVA OOP question below: Consider the following relationship diagram between the Game and VideoGame data defintion classes. Game has a constructor that takes in two parameters, title (String) and cost (double). The VideoGame constructor has an additional parameter, genre (String). In Java, efficiently write the constructors needed within the Game class and VideoGame classes. Hint: Remember to think about the appropriate validation

In a shopping cart, there are various items, which can either belong to the category of household items or electronic items. The following UML diagram illustrates the relationship between items, household items, and electronic items. //Implementation Class public class ShoppingCart{ public static void main(String[] args){ final int MAX_ITEM = 50; Item cart = new Item[MAX_ITEM]; addItem(cart); // populate the item array printItem(cart); } } Considering that all the data definition classes and the implementation class are complete, which of the following Object-Oriented Programming (OOP) concepts do you need to use in the above context? i) Polymorphism ii) Method Overloading iii) Method Overriding iv) Dynamic Binding v) Abstract Class Explain, using course terminology, how you would use any of the above concepts to model the given scenario.
