  • 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 E.g. if an electronic payment is made, the amount must be both withdrawn from one account and added to the other; it cannot complete only one of those steps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
    centralized system
    DBMS
    presentation application
    services services
    user module
    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)
  • 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
