What is one advantage of a database over a flat file system quizlet?

An advantage that a database has over a flat file system is that more information can be generated from the same data. The database component of an information system can generate sufficient business intelligence by accessing just the internal data of an organization.

Which type of databases is not limited by the data’s physical location quizlet?

A distributed database is not limited by the data’s physical location. A select operation pares down a table in a database by eliminating columns according to certain criteria. Although a database can consist of only a single file, it is usually a group of files.

Which operation pares down a table by eliminating columns according to certain criteria?

A select operation pares down a table in a relational database by eliminating columns according to certain criteria. With the indexed sequential access method (ISAM), records cannot be accessed randomly.

What is a component of a data model that defines the boundaries of a database such as maximum and minimum values allowed for a field constraints and access methods?

The “integrity rules” component of a data model defines the boundaries of a database, constraints, and access methods. In a data warehouse, ____ means collecting data from a variety of sources and converting it into a format that can be used in transformation processing.

What is one advantage of a database over a flat file system?

There are several advantages of Database management system over file system. Few of them are as follows: No redundant data: Redundancy removed by data normalization. No data duplication saves storage and improves access time.

Which component of a decision support system DSS manages and coordinates the other major components?

In a decision support system (DSS), the user interface manages and coordinates the database and model base.

Which is a software component of a Management Information System MIS )?

The software components of a management information system (MIS) include input, output, and memory devices. The hardware components of the management information system (MIS) include input, output, and memory devices and vary depending on the application and the organization.

Which of the following best defines an operating system?

An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs.

Which component of a decision support system DSS enables the DSS to perform analysis operations on the information stored in the system?

A user interface enables a decision support system (DSS) to analyze information.

How does a decision support system typically differ from an executive information system?

How does a DSS typically differ from an EIS? An EIS requires data from external sources to support unstructured decisions, where a DSS typically uses internal sources to support semi-structured decisions.

Which module of an Executive Information System EIS is used by developers to configure data mapping and screen sequencing?

Administrative module for managing data access. Builder module for developers to configure data mapping and screen sequencing. Runtime module for using the system.

What are the components of DSS?

Is DBMS a component of DSS?

A decision support systems consists of three main components, namely database, software system and user interface.

What is the difference between database and decision support systems as components of MIS?

The difference between management information system and decision support system is that management information system supports structured decision making while decision support system provides support for unstructured or semi-structured decisions.

What is DSS model?

A model-based DSS is “an interactive computer-based system composed of a user-dialog system, a model processor and a data management system, which helps decision makers utilize data and quantitative models to solve semi-structured problems” (Forgionne et al., 2005, p. 765).
