Exam 2: Information System Building Blocks

Today's best-designed information systems tend to separate the building blocks and force them to communicate across the network. This is called a ______________________________.

Process requirements are frequently specified in terms of work flow.

The technical design of business processes to be automated or supported by computer programs to be written by systems builders is known as:

A layer of utility software that sits between the application software and systems software to transparently integrate differing technologies so that can interoperate is called:

A procedure is a step-by-step set of instructions and logic for accomplishing a business process.

System owners frequently identify services and level of services that they seek to provide customers, suppliers and employees.

Cross-functional information systems are:

A(n) ___________________________ is a step-by-step set of instructions and logic for accomplishing a business process.

Prototyping is a very new and seldom used technique used by system designers of today.

All stakeholders of an information system share the same perspective of the system.

Today the best-designed systems tend to separate the information system into layers that handle the data, process and interface building blocks in a way that allows them to communicate across the network. The goal of this clean layering approach is to allow any one building block to be replaced with another while having little or no impact on other building blocks.

Language-based, machine readable representations of what a software process is supposed to do, or how a software process is supposed to accomplish its task is known as:

Contemporary information systems are interfacing with customers and suppliers using electronic commerce technology, CRM, and SCM over the internet.

A user dialogue describes how the user interacts with the application programs to perform useful work.

Prototyping is a technique for quickly building a functioning, but incomplete model of the information system using rapid application development tools.

The challenge in systems development is to identify, express and analyze business process requirements exclusively in business terms that can be understood by system users.

________________________________ is a layer of utility software that sits between application software and systems software to transparently integrate differing technologies so that they can interoperate.

System designers tend to focus on the technical design of system-to-user communication while system builders focus on the technical design of system-to-system communication.

As far as interface design is concerned system designers are interested in consistency, completeness and user dialogues.

An information system's architecture is:
