  1. Types of Information Systems Dr. D. Bilal IS 582 Spring 2007

  2. Transaction Processing Systems: TPS • Designed to handle a large volume of transactions: • Billing, payroll, order tracking and processing, accounts payable and receivable, securities, trading and cash management, etc.

  3. Decision Support System: DSS • Provides interactive models to help managers make better decisions • Often used by middle and upper managers • Implemented within another system to help users build profiles, cases, etc. to reach decisions • Example: Digichart system

  4. Expert System: ES • Knowledge of experts is captured in a computer to solve problems • Based on Artificial Intelligence to recognize, formulate, solve problems, and learn from experience • Software are called shells • Not successful in all disciplines • Most fruitful in medicine for diagnosis

  5. Office Automation System: OAD • Performs a variety of activities based on its purpose: • word processing, electronic booking, appointments, document imaging, etc.

  6. Information Systems • Information retrieval systems • Databases, Web search engines, online catalogs • Online catalogs • Library automated systems • Software • Hardware • Online Public Access Catalogs (OPACs)

  7. Types of Library Automated Systems • In terms of function: • Stand-alone • Characteristics • Integrated • Characteristics

  8. Types of Library Automated Systems • In terms of interface: • Character-based (e.g., DOS-based) • Almost obsolete • Windows-based • Web-based

  9. Types of Library Automated Systems • In terms of platforms • PC • Macintosh

  10. Types of Library Automated Systems • In terms of software development • In-house • Supplied by automation vendor (turnkey) • Open system (in the public domain)

  11. Modules • OPAC • Circulation • Cataloging • Acquisitions • Serials • Other

  12. Function of OPAC • Information access to local collection • Information access to external collections • Known as the online public access catalog • It is part of the online catalog that users access to locate library materials

  13. Function of circulation • Check-in • Check-out • Item hold • Item reserve • Item recall

  14. Function of circulation • Fines • Overdues • Statistics about collection use • In house • Outside library • Management

  15. Function of cataloging • Input new items (original cataloging) • Revise the cataloging of existing items • File saved records • Import/export of MARC records • Search and retrieval

  16. Function of acquisitions • Item ordering • Item receipt • Item claims • Item cancellation • Item verification • Management

  17. Function of serials • Serials check-in • Serials routing • Serials claim • Serials cancellation • Serials renewal • Management

  18. Benefits of Library Automation • Enhances use of a collection • Eliminates routine tasks • Expedites and simplifies tasks • Resource sharing (ILL, Union catalogs) • Collection mapping

  19. Benefits of Automation • Wide access to resources via a federated search (as available) • Frees some cataloging time • Reduces amount of time spent on ordering and processing material

  20. Pitfalls of Automation • Time-consuming • Costly • New tasks (e.g., problem-shooting of software & hardware; training) • Access to a collection can be denied when the system is down • Federated searches - information overload
