Question 1

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.

Accepted Answer

A difficult user interface can be a deterrent for managers to use computers and quantitative analyses to their full potential, even if the technology is available.

Question 2

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

Accepted Answer

Business analytics involves using data and models to gain insights and make better decisions that can ultimately enhance a company's performance or competitive advantage.

Question 3

User interface of a DSS includes not only the hardware and software but also factors that deal with ease of use,accessibility,and human-machine interactions.

Accepted Answer

The user interface of a DSS includes various factors that relate to how easy it is for users to interact with the system, including hardware and software, but also elements like accessibility and human-machine interactions.

Question 4

If the main user of a DSS is replaced by another,less knowledgeable user (in terms of the decision-making problem and environment),the DSS will generally be less effective.

Accepted Answer

DSS is designed to provide decision-making support to a specific user by using their knowledge and expertise. In case of replacement with a less knowledgeable user, the DSS may not be able to provide the same level of support and thus be less effective.

Question 5

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.

Accepted Answer

Integrating data with models allows for more accurate and informed decision making within a DSS.

Question 6

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

Accepted Answer

Different Decision Support Systems (DSS) may have varying components based on the specific needs they are designed to meet, such as data management tools, model management tools, and user interface, but the composition and capabilities can vary widely depending on the application.

Question 7

Knowledge Management Systems (KMS)that are developed around communities that practice collaborative work are a type of document-driven DSS.

Accepted Answer

Knowledge Management Systems (KMS) that are developed around communities practicing collaborative work are typically more focused on facilitating knowledge sharing and collaboration rather than being primarily document-driven. They often utilize various tools and platforms to enable knowledge exchange, rather than focusing solely on documents.

Question 8

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.

Accepted Answer

Microsoft Access is primarily a database management system and does not inherently include statistical packages, a linear programming package, and financial and management science models. These functionalities would require additional software or integrations.

Question 9

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.

Accepted Answer

The answer of A key component of DSS is the...

Question 10

Accepted Answer

The answer of Planned models are used mainly by middle...

Question 11

A DSS database can include multimedia objects,e.g.,pictures,maps,and sounds.

Accepted Answer

A DSS (Decision Support System) database can indeed include multimedia objects such as pictures, maps, and sounds to aid in decision-making processes.

Question 12

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

Accepted Answer

Poor quality data can result in inaccurate, incomplete, or inconsistent information which can lead to ineffective decision-making and ultimately waste resources. Therefore, data quality is a crucial issue in data management.

Question 13

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.

Accepted Answer

Capturing data from multiple sources can be a complex process that requires careful planning and integration to ensure data accuracy and consistency. It may involve data extraction, transformation, and loading (ETL) processes, as well as data cleansing and formatting to make the information usable in the DSS database or data warehouse.

Question 14

Business intelligence (BI)is typically built to support the solution of a certain problem or to evaluate an opportunity.

Accepted Answer

The answer of Business intelligence (BI)is typically built to support...

Question 15

A DSS can be custom-made by assembling the system from a variety of tools including databases,Web servers and clients,and analytical engines,often from several vendors.

Accepted Answer

This statement is true. A Decision Support System (DSS) can be created using a combination of various technologies such as databases, web servers, analytical engines, etc. These technologies can be sourced from multiple vendors and customized to meet specific requirements.

Question 16

Decision makers at the Avantas Company selected Planners Lab for data analysis because Planners Lab offered an easy-to-use alternative to Excel to create "what-if" scenarios.

Accepted Answer

The answer of Decision makers at the Avantas Company selected...

Question 17

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

Accepted Answer

Data integration is crucial for the successful implementation of an enterprise information system like a supply management system, as it involves integrating data from various sources, ensuring consistency and accuracy, and avoiding duplication of data. Failure to address data integration issues can lead to operational inefficiencies, errors, and inaccurate decision-making. Therefore, it is essential to have a data integration strategy in place before implementing any enterprise information system.

Question 18

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

Accepted Answer

DSS often deal with problems that cannot be solved using pre-built models and require customization using programming tools and languages.

Question 19

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.

Accepted Answer

XML is becoming more important in DSS due to the growth of mobile commerce applications on handheld devices such as PDAs and cell phones, so the statement is true.

Question 20

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

Accepted Answer

Database directory is a catalog of all the data (e.g. tables, columns, indexes) in a database system, not the models and other software in the model base.
