Exam 1: Introduction to Systems Analysis and Design

In object-oriented design,built-in processes called _____ can change an object's properties.

In a(n)_____ model,the result of each phase is called a deliverable,which flows into the next phase.

Structured analysis is a traditional systems development technique that uses a series of phases,called the _____,to plan,analyze,design,implement,and support an information system.

_____ provides vital protection and maintenance services for system hardware and software,including enterprise computing systems,networks,transaction processing systems,and corporate IT infrastructure.

One of the disadvantages of _____ methods of system development is that the overall project might be subject to scope change as user requirements change.

The systems implementation phase of the systems development life cycle (SDLC)includes an assessment,called a _____,to determine whether the system operates properly and if costs and benefits are within expectation.

Transaction processing (TP)systems are inefficient because they process a set of transaction-related commands individually rather than as a group.

In object-oriented analysis,an object is a member of a(n)_____,which is a collection of similar objects.

During the _____ of the systems development life cycle (SDLC),a new system is constructed.

A(n)_____ shows the data that flow in and out of system processes.

_____ design and construct web pages,monitor traffic,manage hardware and software,and link web-based applications to a company's information systems.

Object-oriented methods provide an easy transition to O-O programming languages such as C++,Java,and Swift.

When planning an information system,a company must consider how a new system will interface with older systems,which are called horizontal systems.

Examples of company-wide applications,called legacy applications,include order processing systems,payroll systems,and company communications networks.

Which method of system development stresses intense team-based effort and reflects a set of community-based values?

Since middle managers focus on a longer time frame,they need less detailed information than top managers,but somewhat more than supervisors who oversee day-to-day operations.

Who is a knowledge worker,and why is this kind of worker required by successful companies?

_____ is a systems development technique that tests system concepts and provides an opportunity to examine input,output,and user interfaces before final decisions are made.

The _____ usually begins with a formal request to the IT department,called a systems request,which describes problems or desired changes in an information system or a business process.

Agile methods typically use a(n)_____ ,which represents a series of iterations based on user feedback.
