Questions On Advance Software Engineering

They show the interaction between objects to create a functioning system and emphasize what must happen in the system being modeled. Since behavior diagrams illustrate the behavior of a system, so they are used extensively to describe the functionality of software systems, and all

In the object-oriented modelling class diagrams are very important. In data modelling techniques class diagrams are used. These class diagrams are represented by using the box symbol.

Activity diagrams are graphical representations of workflows of stepwise activities and actions with support for choice, iteration and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e. workflows). Activity diagrams show the overall flow of control.

As the information system is designed, implementation decisions describing how the system will work are made. Data flow diagrams offer those implementation details, including data stores that refer to files and database tables, programs and human actions that perform processes. The automated parts of the system are differentiated from the manual parts by the human-machine boundary (Dennis, Wixom,

The Rectangular shapes in Black represent the internal job of the Program at a particular section or point

The following analysis document provides an entity relationship (E-R) diagrams in support of a car-insurance company requirements as detailed in the assignment statement.

A flowchart is a diagram that depicts the “flow” of a program. It contains symbols that represent each step in the program (Pearson Education, 2012). It has 4 general structures:

This diagram is used to break down wide sorts of data and information into increasing levels of detailed. It maps

A context diagram consists of a high level view of the system that helps us establish the boundaries of the current system under investigation and thus allowed us to implement our proposal. The context diagram can be useful to identify the project scope and help secure agreements with the consignors. The current system above shows how the current recordkeeping system interacts with different entities or sources and how the flow of information is being

software development. It provides a background in applications software development and testing techniques through a

An explanation of the distinction between systems analysis and systems design and a description of the activities involved in each

The interview session has been done by include an open-ended and closed-ended question which are related to the implemented project. Next, sampling technique is executed by system analyst who does evaluation to the current system or prototype. These processes give feedback in evaluation form that filled after tested the system. Lastly, observation is performed by using questionnaire form. According to Burch (1992), the questionnaire is analyzed and transform into structured form that easy to understand. After all information has been collected, structuring of system requirement takes place. It focused on development process modeling which perform “graphically representing the process, or actions, that capture, manipulate, store, and distribute data between a system and environment” (Hoffer, George, & Valacich, 2012, p. 182). In this step, Data flow diagram (DFD) is structured by system analyst using special tools and techniques to create a decision table. According to Hoffer, George and Valacich (2012), decision table is a “diagram of process logic where the logic is reasonably complicated” (p. 200). This table is useful to help system analyst to make a decision toward the project. Then all information’s gained from this phase are documented in System Analysis Report (SAR) that acts as a guideline or reference to the future system development project (Burch, 1992).

The class diagram is the main building block in object oriented modelling. They are being used both for general conceptual modelling of the systematic of the application, and for detailed modelling translating the models into programming code. The classes in a class diagram communicate to both the primary objects as well as communications in the application and the objects to be customized.

Software engineering (SE) is the profession concerned with specifying, designing, developing and maintaining software applications by applying technologies and practices from computer science, project management, and other fields.

A use case diagram is a type of behavioral diagram defined by the Unified Modeling Language (UML). Its purpose is to present a graphical overview of the functionality provided by a system in terms of actors, their goals- represented as use cases- and any dependencies between those
