The systems analysis phase is the second phase of the systems development life cycle $($SDLC$).$ There are four integral parts of the systems analysis phase that you will explore in this project.

Systems analysis activities include requirements modeling, data and process modeling, object modeling, and consideration of development strategies.

Requirements modeling includes fact$-$finding to describe the current system and identification of the requirements for the new system: output, input, process, performance, and security.

$$ Create a simple use case diagram similar to the diagram in Figure $4-18$ in Chapter $4$ Requirements Engineering. The use case diagram does not have to be a graphical diagram, but it should clearly identify the actor, the actor interaction, and the use case to show the interaction between the user and the information system. Below is a written example of the graphical use case diagram in Figure $4-18$ to show how you can create the use case diagram in written format. You can use an example from an order entry system, from a student registration system, or a different system. You will need to use an example other than one from the book. You may create the Use Case Diagram in either a graphical format or a written format.

Actor interaction $$ Submits Card Data

Use Case $$ Validate Credit Card

Data and process modeling involves three main items: data flow diagrams, a data dictionary, and process descriptions.

$$ Create a simple process description used in object$-$oriented development using a sequence control structure. There is a simple example of a sequence control structure in Chapter $5$ Data and Process Modeling in Figure $5-24.$ The diagram does not have to be in a graphical format as in the example in the book, but it should clearly represent each step in the sequence structure. Below is a written example of the graphical sequence structure in Figure $5-24$ to show you how to create the sequence structure in written format. You can use an example from an order entry system, from a student registration system, or a different system. You will need to use an example other than the one in the book. You may create the Sequence Structure in either a graphical format or a written format.

Object$-$oriented analysis describes an information system by identifying objects and representing the system in terms of those objects in object modeling. The end product of object$-$oriented analysis is an object model.

$$ Explain relationships among objects and classes in object$-$oriented analysis to include the concepts of inheritance.

Show the concept of inheritance by completing the following. List one object, at least three attributes of the object, and at least two methods of the object. Consider a child object that would inherit the characteristics of the parent object. List the child object, at least $5$ attributes of the child object, and the methods of the child object. There is an example of a Parent and a Child object in Chapter $6$ Object Modeling in Figure $6-9.$ The object does not have to be in a graphical format as in the example in the book, but it should clearly represent the parent and the child object, the attributes each object, and the methods of each object. Below is a written example of the graphical objects in Figure $6-9$ to show how to create the graphical representation in a written format. You can use an example from an order entry system, from a student registration system, or a different system. You will need to use an example other than the one in the book. You may create the objects in either a graphical format or a written format.

The final activity in the systems analysis phase is consideration of development strategies, which includes evaluation of alternative solutions, preparation of the system requirements document, and presentation of the system requirements document to management.

$$ Explain the benefits of working as an evaluation and selection team in the evaluation and selection of alternatives in consideration of development strategies. Include the primary objective of the team in the explanation.

$$ One alternative for systems development that could be selected by a company is to acquire a software package. As a part of the software acquisition process, it is helpful to use an evaluation model technique to compare alternatives. Two evaluation models that can be utilized are the unweighted evaluation model and the weighted evaluation model. In Chapter $7$ Development Strategie
