Exam 3: Decision Support Systems Concepts, Methodologies, and Technologies:

The operation of capturing data from several sources and loading it to a data warehouse is called:

A DSS is an approach for supporting decision making.It uses an interactive,flexible,adap computer-based information system (CBIS)developed to support the solution to a specific,________ management problem.

Explain the role,components,and importance of the user interface (dialog)subsystem.

________ systems have models embedded in them,but they are still not well understood in practice.

________ models are used to support the day-to-day working activities of the organization.Typical decisions involve e-commerce transaction acceptance,approval of personal loans by a bank,production scheduling,inventory control,maintenance planning and scheduling,and quality control.

List the four main functions of MBMS (model base management system)software

Advanced DSS are equipped with a component called a(n)________ subsystem.This component can supply the required expertise for solving some aspects of the problem and provide knowledge that can enhance the operation of other DSS components.

An effective database and its management can support many managerial activities; however,the real power of a DSS occurs when data are integrated with its models.

________ control and coordinate the use of software to support group work.

The models in the model base can also be classified by functional areas or by ________.

As the size of the data to be stored and accessed increases,processing times and storage space also grow,sometimes dramatically.Large databases present major ________ problems.

Discuss the advantages of developing a models for a DSS with Planners Lab instead of traditional programming languages or spreadsheets?

To create or load a DSS database or a data warehouse,it is often necessary to capture data from several sources,which is a simple (trivial)process.

A key issue in data management is that of data quality.Poor quality data,which leads to poor quality information leads directly to waste.

When voice input with accompanying ________ software is used,verbal instructions with accompanied actions and outputs can be invoked.

Most data mining applications include intelligent systems,such as artificial neural networks (ANN)and rule induction methods for expert systems (ES),to search for potentially profi ________ in data.

Business analytics (BA)implies the use of models and data to improve an organization's performance or competitive posture

Users of DSS communicate with and command the DSS through the ________ subsystem.

________ is the physical data repository organized to provide enterprise wide,cleaned data in a standardized format.

All of the following are characteristics of Planners Lab except:
