- The decision making process.
- Decision making essentials.
Support : Enhancing Decision Making with MIS :
Operational Support Systems
- Transactional information encompasses all the information contained within a single business process or unit of work, and its primary purpose is to support the performance of daily operational or structured decisions.
- Online transaction processing (OLTP) is the capture of transaction and event information using technology to :
- process the information according to defined business rules.
- store the information.
- update existing information to reflect the new information.
- Transaction processing system (TPS) is the basic business system that serves the operational level (analysts) and assists in making structured decisions.
Managerial Support Systems
- Analytical information encompasses all organizational information, and its primary purpose is to support the performance of managerial analysis or semistructured decisions.
- Online analytical processing (OLAP) is the manipulation of creation to create business intelligence in support of strategic decision making.
- The following are common decision support systems (DSS) analysis techniques :
- What - If Analysis.
- Sensitivity Analysis.
- Goal - Seeking Analysis.
- Optimization Analysis.
Strategic Support Systems
- Executive information system (EIS) is a specialized DSS that supports senior-level executives and unstructured, long - term, nonroutine decisions requiring judgement, evaluation, and insight.
- Granularity refers to the level of detail in the model or the decision-making process.
- Visualization produces graphical dispalys of patterns and complex relationships in large amounts of data.
- Digital dashboard a common tool that supports visualization.
- Digital dashboards offer the following capabilities :
The Future : Artificial Intelligence
=> Artificial intelligence (AI) simulates human thinking and behavior, such as the ability to reason and learn.
=> Intelligent systems are various commercial applications of artificial intelligence.
=> There are many categories of AI systems such as :
1. expert systems.
are computerized advisory programs that imitate the reasoning processes of expert in solving difficult problems.
2. neural networks.
also called an artificial neural network, is a category of AI that attempts to emulate the way the human brain works.
3. genetic algorithms.
is an artificial intelligence system that mimics the evolutionary, survival-of-the-fittest process to generate increasingly better solutions to a problem.
4. intelligent agents.
is a special-purpose knowledge-based information system that accomplishes specific tasks on behalf of its users.
5. virtual reality.
is a computer-simulated environment that can be a simulation of the real world or an imaginary world.
