COLLABORATION SYSTEM IN MANUFACTURING

It is designed for one basic purpose, to help unite employees or people that are working on similar task, or it could be the exact task and system helps unite them to complete their task and achieve whatever goal that task sets out to do.

E.g. Slovak, Instant Messaging

ENTERPRISE COLLABORATION SYSTEM Communicate Coordinate Collaborate and Cooperation

TOOLS USED

Electronic mail Voice mail Bulletin board systems Fax Video conferencing tools

COLLABORATION SYSTEM IN MANUFACTURING

Structured collaboration system Easier to organize Excellent for hierarchical organizations Increases proficiency

Limitations of structured collaboration system Same workflow information Can cause groupthink Encourages lack of creativity

ENTERPRISE APPLICATION INTEGRATION The use of software and computer

systems architectural principles to integrate a set of enterprise computer applications.

It is an integration framework composed of collection of technologies and services which form a middleware to enable integration of systems and applications across the enterprise.

TRANSACTION PROCESSING SYSTEMS A transaction processing system is a type of

information system. TPSs collect, store, modify, and retrieve the transactions of an organization.

A transaction is an event that generates or modifies data that is eventually stored in an information system.

The essence of a transaction program is that it manages data that must be left in a consistent state. E.g. if an electronic payment is made, the amount must be both withdrawn from one account and added to the other; it cannot complete only one of those steps

SINGLE-USER SYSTEM

Presentation Services - displays forms, handles flow of information to/from screen

Application Services - implements user request, interacts with DBMS

ACID properties automatic (isolation is trivial) or not required (this is not really an enterprise)

presentation applicationservices services

DBMS

user module

centralized system

CENTRALIZED MULTI-USER SYSTEM

Dumb terminals connected to mainframe Application and presentation services on

mainframe ACID properties required

Isolation: DBMS sees an interleaved schedule

Atomicity and durability: system supports a major enterprise

Transaction abstraction, implemented by DBMS, provides ACID properties

CENTRALIZED MULTI-USER SYSTEM

TRANSACTION PROCESSING IN A DISTRIBUTED SYSTEM

Decreased cost of hardware and communication make it possible to distribute components of transaction processing system Dumb terminal replaced by computers

Client/server organization generally used
