Exam 13: Application Architecture and Modeling

A reason that a physical process might be split into multiple logical processes is to add additional data requirements.

The benefit of the distributed data and application client/server system is that by moving the application logic to its own server, that logic need only be maintained on the server instead of all of the clients.

A set of computers connected over a relatively short distance to one or more servers is known as a(n):

Application middleware allows a programmer to build user interface components that talk to web browsers or desktop GUI.

A physical data flow represents any of the following: (1) the planned implementation of an input to or output from a physical process; (2) a database command or actions such as create, read, update, or delete; (3) the import of data from or the export of data to another information system across a network; or (4) the flow of data between two modules or subroutines within the same program.

What technique truly distributes rows and columns of a relational database to specific database servers with little or no duplication between servers?

A(n) __________ uses Internet technology to integrate desktop, work group, and enterprise computing.

The logical data flow diagrams specify the technologies to be used to implement information systems.

Application architecture is a specification of the technologies to be used to implement information systems.

Horizontal partitioning is when different rows in a database are assigned to different database servers.

To identify the processors and their locations, the developer utilizes: (1) an enterprise information architecture if it exists; and (2) the advice of competent network managers and/or specialists should be solicited to determine what's in place, what's possible and what impact the system may have on the computer network.

A(n) ____________________________ is one in which the data, process, and interface components of an information system are distributed to multiple locations in a computer network. Accordingly, the processing workload required to support these components is also distributed across multiple computers on the network.

A(n) ______________________________ is either a processor, such as a computer or person, or the technical implementation of specific work to be performed, such as a computer program or manual process.

Contrary to popular belief, batch input technologies are not quite obsolete.

A distributed data and application client/server system is called three-tiered or n-tiered computing.

A reason that a logical process might be split into multiple physical processes is because part of the process is performed by _______________________, and part is to be performed by the ______________________.

A(n) _________________________ system is a solution in which the presentation, presentation logic, application logic, data manipulation and data layers are distributed between client PCs and one or more servers.

A(n) ___________________________ system is a solution in which the presentation and presentation logic layers are shifted from the server of a legacy system to reside on the client. The application logic, data manipulation and data layers remain on the server (usually a mainframe.)

Another name for Internet-based computing is network computing.

In distributed systems, a central multiuser computer hosts all components.
