System Types by Activity Flashcards
What is the purpose of executive support systems (ESS) and strategic support systems (SSS)?
A subset of decision support systems (DSS) especially designed for forecasting and making long-range, strategic decisions. As such, they have a greater emphasis on external data. Sometimes called “DSS for dummies.”
What are decision support systems (DSS)?
These systems provide information to mid- and upper-level management to assist them in managing non routine problems and in long-range planning. Unlike MISs, DSSs frequently include external data in addition to summarized information from the TPS and include significant analytical and statistical capabilities.
What are data-driven decision support systems (data-driven DSS)?
These systems process large amounts of data to find relationships and patterns that are useful in decision making.
Define management information systems.
Systems designed to support routine management problems based primarily on data from transaction processing systems.
What is a data warehouse?
A database for organizational decision making. Data from the live databases are copied to the warehouse so that data can queried without reducing the performance (i.e., speed) or stability (i.e., reliability) of the live systems.
What are operational systems?
These systems support the day-to-day activities of the business (purchasing of goods and services, manufacturing activities, sales to customers, cash collections, payroll, etc.) Also known as transaction processing systems (TPS).
What is data mining?
Searching data in a warehouse to discover patterns and relationships in historical data.
What is a knowledge work system?t
Knowledge work systems facilitate the work activities of professional-level employees (engineers, accountants, attorneys, etc.) by providing information relevant to their day-to-day activities (e.g., how the company has handled specific types of audit exceptions) and/or by automating some of their routine functions (e.g., computer-aided systems engineering [CASE] packages used by programmers to automated some programming functions).
