A transaction process system (TPS) is an information processing
system for business transactions involving the collection, modification and
retrieval of all transaction data. Characteristics of a TPS include
performance, reliability and consistency.TPS is also known as transaction
processing or real-time processing.
Executive Support System (ESS) is a reporting tool (software) that
allows you to turn your organization's data into useful summarized
reports. These reports are generally used by executive level managers for quick
access to reports coming from all company levels and departments such as
billing, cost accounting , staffing, scheduling, and more.
In addition to providing quick
access to organized data from departments, some Executive Support System tools
also provide analysis tools that predicts a series of performance outcomes over
time using the input data. This type of ESS is useful to executives as it
provides possible outcomes and quick reference to statistics and numbers needed
for decision-making.
Decision Support Systems (DSS), the term refers to an interactive computerized
system that gathers and presents data from a wide range of sources, typically
for business purposes. DSS applications are systems and subsystems that
help people make decisions based on data that is culled from a wide range of
sources.
For example: a national on-line
book seller wants to begin selling its products internationally but first needs
to determine if that will be a wise business decision. The vendor can use a DSS
to gather information from its own resources (using a tool such as OLAP) to
determine if the company has the ability or potential ability to expand its
business and also from external resources, such as industry data, to determine
if there is indeed a demand to meet. The DSS will collect and analyze the data
and then present it in a way that can be interpreted by humans. Some decision
support systems come very close to acting as artificial intelligence agents.
Expert systems-A computer application that performs a
task that would otherwise be performed by a human expert. For example, there
are expert systems that can diagnose human illnesses, make financial forecasts,
and schedule routes for delivery vehicles. Some expert systems are designed to
take the place of human experts, while others are designed to aid them.
Expert systems are part of a
general category of computer applications known as artificial intelligence. To
design an expert system, one needs a knowledge engineer, an
individual who studies how human experts make decisions and translates the
rules into terms that a computer can understand.
A data warehouse is a repository of an organization's
electronically stored data. Data warehouses are designed to facilitate
reporting and analysis. A data warehouse (DW, DWH), or
an enterprise data warehouse (EDW), is a system used for reporting and data
analysis. Integrating data from one or more disparate sources creates a central
repository of data, a data warehouse (DW). Data warehouses store current and
historical data and are used for creating trending reports for senior
management reporting such as annual and quarterly comparisons.
Data mining
(sometimes called data or knowledge discovery) is the process of analyzing data
from different perspectives and summarizing it into useful information -
information that can be used to increase revenue, cuts costs, or both. Data
mining software is one of a number of analytical tools for analyzing data. It
allows users to analyze data from many different dimensions or angles,
categorize it, and summarize the relationships identified. Technically, data
mining is the process of finding correlations or patterns among dozens of
fields in large relational databases.
