Executive Information System
An Executive
Information System (EIS) is a type
of management
information system intended to facilitate and support the
information and decision-making needs
of senior executives by providing easy access to both internal and external
information relevant to meeting the strategic goals
of the organization. It is commonly considered as a specialized form
of a Decision Support System (DSS).
Decision Support Systems
Decision Support
Systems (DSS) are a specific class
of computerized
information systems that supports business and organizational decision-making activities. A properly-designed DSS is an interactive s
oftware-based system intended to help decision makers compile useful
information from raw data, documents, personal knowledge, and/or business models to identify and solve problems and make decisions.
Management Reporting Systems
Management Reporting
Systems are intended to provide aggregated data about the performance
of the organization. Usually these are created from data generated by the knowledge or operational layers
of information systems
Business Intelligence Systems
Business Intelligence (BI) refers to skills, technologies, applications and practices used to help a business acquire a better understanding
of its commercial context. Business intelligence may also refer to the collected
information itself.
BI technologies provide historical, current, and predictive views
of business operations. Common functions
of business intelligence technologies are reporting, OLAP, analytics, data mining, business performance management, benchmarks, text mining, and predictive analytics.
Popular closed source (e.g. Business Objects (SAP) or Cognos) and open source (e.g. JasperS
oft or Pentaho) s
oftware
often have the functionality that can provide
information for the
different types of information systems that are shown in the pyramid.
Office Information Systems
Office
Information Systems provide
information to the organization that is not directly available from operational support
systems.
Often this is textual data(e.g.
Office-documents or E-mail), but it can also be a CRM (Customer Relationship Management) system. Intranet and wiki's are very popular applications
of these.
Knowledge Management Systems
Knowledge Management
Systems are meant to facilitate knowledge management in an organization. As described in our
approach and in the
knowledge creation cycle they are only part (although very important)
of a knowledge management strategy. It is not an
Office
Information System as is
often thought and should be smaller in size than
Office
Information System. If implemented and used properly they can be considered as force multipliers for an organization.
Transaction Processing Systems
A Transaction Processing System is a set
of information which process the data transaction in database system that monitors transaction programs (a special kind
of program). The essence
of a transaction program is that it manages data that must be left in a consistent state. These are usually databases.
