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

Database directory is a catalog of all the models and other software in the model base.

All DSSs have common components that enable them to provide the same capabilities and support to users.

A(n)________ contains routine and special statistical,financial,forecasting,management science,and other quantitative models that provide the analysis capabilities in a DSS.

A key component of DSS is the ability to visualize the results.For example,it is important for executives to visualize the results of modifying assumptions.

The de facto DSS hardware standard is a(n)________ through which the DBMS provides data.

Data integration issues generally become critical when implementing an enterprise information system like a supply management system.

XML (eXtensible Markup Language)is becoming more important in DSS due to the growth of mobile commerce applications,on handheld devices,e.g.,PDAs and cell phones.

Which of the following subsystem can support any of the other subsystems or act as an independent component? It also provides intelligence to augment the decision maker's own?

The most common end-user tool for DSS development is Microsoft Access,which includes statistical packages,a linear programming package,and financial and management science models.

Data directory is a catalog of all the data in the database.It contains ________,and its main function is to answer questions about the availability of data items,their source,and their exact meaning.

________ deal with specific problems that are usually neither anticipated nor recurring.

A database is created,accessed,and updated by a(n)________.

The ________ is especially appropriate for supporting the intelligence phase of the decision-making process by helping to scan data and identify problem areas or opportunities.

Optimization,simulation,statistics systems,and ES currently run in ________.These developments simplify access to data,models,and knowledge,and simplify their integration.

3Because DSS deal with semistructured or unstructured problems,it is often necessary to customize models,using programming tools and languages.

A(n)________ is a collection of interrelated data,organized to meet the needs and structure of an organization that can be used by more than one person for more than one application.

A difficult user interface is one of the major reasons why managers do not use computers and quantitative analyses as much as they could,given the availability of these technologies.

Planners Lab is a DSS ________ language.

One key issue that DBMS must handle is data security.Data can be ________ so that even in the case of unauthorized access,the viewed data is scrambled and unintelligible.

An ________ allows the manager to benefit from the decision support system without actually having to use the keyboard.
