1. Types of Information Systems Dr. D. Bilal IS 592 Spring 2005

2. Decision Support System: DSS  Provides interactive models to help managers make better decisions  Often used by middle and upper managers

3. Executive Support System: ESS  Sophisticated version of a DSS  Used to match top managerial needs

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

5. 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.

6. Operations Information Systems: OIS  Gathers comprehensive data, organizes it and summarizes it in a form valuable to managers.  Provides sales, inventory, performance- oriented data, customer service and productivity information, etc.

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

8. Definitions  Automation  Library automation  Automated System – Software – Hardware  Online catalog – Opac

9. Types of automated systems  In terms of function: – Stand-alone Characteristics – Integrated Characteristics

10. Types of automated systems  In terms of interface: – Character-based (becoming obsolete) – Windows-based – Web-based

11. Types of automated systems  In terms of platforms – PC – Macintosh

12. Modules  OPAC  Circulation  Cataloging  Acquisitions  Serials  Other

13. 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

14. Function of circulation  Check-in  Check-out  Item hold  Item reserve  Item recall

15. Function of circulation  Fines  Overdues  Statistics about collection use – In house – Outside library  Management

16. 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

17. Function of acquisitions  Item ordering  Item receipt  Item claims  Item cancellation  Item verification  Management

18. Function of serials  Serials check-in  Serials routing  Serials claim  Serials cancellation  Serials renewal  Management

19. Benefits of Library Automation  Provides enhanced use of a collection  Eliminates routine tasks  Expedites and simplifies tasks  Allows for resource sharing (ILL, Union catalogs)  Allows for collection mapping

20. Benefits of Library Automation  Frees cataloging time  Reduces amount of time spent on ordering and processing material  Provides access to and inclusion of Web resources

21. Pitfalls of Library 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
