Enterprise

Perspective
Enterprise Systems are ones that have a large scope involve or integrate all parts of an organization.
Remember that we’ve already studiedEnterprise Collaboration Systems For an ECS, like Outlook, both the grunts and the
President use it... Its not specific to the functional areas. Its not specific to the operations level, tactical level, or
strategic level

Perspective
In the software world, Enterprise is a buzz word, which usually implies that the system is very expensive, but can do a lot
In the e-commerce era, an Enterprise is often more than one company and the boundaries are unclear...virtual companies, etc. Sometimes Enterprise implies that more than
one company is involved.

Supply Chain – Value Chain
Enterprise Systems come from a need to streamline the value chain in a company.
Functional areas, from Manufacturing to Marketing, need to be connected.
1. Multiple functional business systems are being replaced by one Enterprise Systems
2. Or, Enterprise System are built on top of several functional systems.

EAI: Enterprise Application Integration
How does a business interconnect its information systems.
Connects Front Office Systems with Back Office Systems
Example: When an order is complete, have the order application tell the accounting system to send a bill and alert shipping to send out the product.

EAI: Enterprise Application Integration
EAI provides middleware (Middle Software) that performs Data conversion between different
systems coordinates Communication and Message
passing between systems The idea is to use the existing systems, but to
have a super-system for connecting related systems.

Summary
There are six types of information systems 6 categories: ECS, TSP, PCS, MIS, DSS, EIS
There are 5 functional areas of business Some system are designed for a specific
functional area: Accounting An ECS can touch all the functional
business areas A TPS might touch 3-4 areas

Summary
ECS and TPS are cross-functional. Some large functional systems, picture a
huge accounting system, can fit into more than 1 category, i.e., both an MIS and TPS.
Enterprise Systems by their nature are both cross-functional and fit into several categories.
