Software Engineering Final Exam 2022| Graded A+ What are some headings of the principles in ACM/IEE code of ethics? - Profession - Product - Client and Employer What are some major causes of software failure? - Increased System Complexity - Failure to use software engineering methods In customized product development, which phase dominates the cost of the system? Software Evolution What are some attributes of good software? - Dependability - Efficiency - Maintainability - Security What is the difference between Software Engineering and Computer Science? Software engineering is an engineering discipline that is concerned with all aspects of software production. Computer science focuses on theory and fundamentals Software engineering is concerned with the practicalities of developing and delivering useful software. What are the principle components of a textual use-case description? - The actors involved - A description of the interactions - The data exchanged How is generalization used to simplify the models of a system with many similar objects? A super-class generalizes all of the objects sharing common attributes and methods Common attributes and methods of similar objects are associated with a super-class What perspectives should be used for developing models of a software system? - External - Interaction - Behavioral - Structural What UML diagram types may be used to represent the essential features of a system? - Use case - Activity - Sequence What are the claimed benefits of model-driven engineering? - By using powerful generation tools, implementations of the same system can be automatically generated for different platforms. - Engineers can work at a high level of abstraction without concern for implementation details. - Errors are reduced and the design and implementation process is sped up. What is true about pipe and filter architecture? - Commonly used in data-processing applications where inputs are processed in separate stages to generate related outputs - Each processing component is discrete and carries out one type of data transformation What are some fundamental questions that should be addressed in architectural design? - Is there a generic application architecture that can be used? - What architectural style or styles are appropriate? Select correct statements related to the Model-View-Controller (MVC) architectural pattern. - The MVC separates presentation and interaction from the system data - The system is structured into three logical components that interact with each other - The model component of MVC manages the system data and associated operations on that model What are some characteristics of transaction-processing applications? - They are database-centered applications that process user requests for information and update the information in the database. - Integrity of the database is maintained What are the principal functions of the 4 layers in a generic layered information system architecture? - User communications, authentication and authorization - Information retrieval and modification - Database and transaction management - User interface What are some essential elements of a design pattern? A statement of the consequences of applying the pattern A description of the problem and when the pattern can be applied
