Title: Types of Information Systems


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
