Decision Support System: DSS
 Provides interactive models to help
managers make better decisions
 Often used by middle and upper managers
Executive Support System: ESS
 Sophisticated version of a DSS
 Used to match top managerial needs
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
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.
Operations Information Systems:
OIS
 Gathers comprehensive data, organizes it
and summarizes it in a form valuable to
managers.
 Provides sales, inventory, performanceoriented data, customer service and
productivity information, etc.
Office Automation System: OAD
 Performs a variety of activities based on its
purpose:
– word processing, electronic booking,
appointments, document imaging, etc.

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

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
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
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
