Exam 13: Application Architecture and Modeling

The information system application layer that provides the actual user interface is known as:

A reason that a logical process might be split into multiple physical processes is to add processes that are necessary to handle exceptions or to implement security requirements and audit trails.

In batch processing, transactions are accumulated into batches for periodic processing. The batch inputs are processed to update databases and produce appropriate reports.

Process partitioning is a self-contained collection of processes, data stores and data flows that share similar design attributes.

A class of CASE tools, sometimes called ___________________, automatically read a character user interface (CUI) and generate a first-cut graphical user interface (GUI).

___________________________________ requires that the presentation, application, and data layers of an application be physically separated.

Partitioning is the act of determining how to best distribute or duplicate application components (data, processes, and interfaces) across the network.

OCR is an example of what kind of data entry?

An application system can be mapped into how many different layers?

A physical data flow diagram can be used to communicate the technical implementation characteristics of an information system.

With the development of an intranet and corporate applications in the intranet environment, multiple different computer architectures are no longer an issue because everything runs in a(n)_________________________________.

Image and document interchange is particularly useful in applications in which the form images or graphics are required.

It is important to understand the difference between file server systems and distributed data client/server systems. Both store their actual databases on a server. But only file server systems execute all data manipulation commands to create, read, update and delete records on a server.

A(n) _______________________________is a software program that controls access to and maintenance of the stored data in the relational format. It also provides for backup, recovery and security. It is sometimes called a client/server database management system.

A transaction server hosts services that ultimately ensure that all database updates for a single business transaction succeed or fail as a whole.

A wide area network (WAN) is a set of client computers connected to one or more servers through either cable or wireless connections over a relatively short distance.

In _______________________________, transactions are accumulated into batches for periodic processing. The batch inputs are processed to update databases and produce appropriate reports.

A server that hosts one or more shared databases and executes all database commands and services for information systems is known as a(n):

Image and document interchange is similar to EDI except that the actual images of forms and data are transmitted and received.

A physical data store represents the implementation of one of the following (name three) __________________.
