Developing Databases and Selecting an Appropriate Library System

What is a Database Management System (DMBS)?

• Database is an organized collection of related data.

• Computerized databases are those stored on computer-readable media such as disks, diskettes, tapes, and CD-ROMs. Computerization of data does not ensure that they form a database.

• A DBMS comprises programs to store, retrieve, and otherwise manage a computerized database, as well as to provide interfaces to application programs and to nonprogramming users.

Why Use a Database Management System?

• Storing and retrieving data• Managing metadata• Limiting and controlling redundant data in

multiple systems• Supporting simultaneous data sharing• Providing transaction atomicity• Providing authorization and security services• Enforcing business rules• Increasing programmer productivity

What is the MARC?

MAchine Readable CatalogingDescription and headings of all items in the catalog created according to AACR1960, Library of CongressUNIMARC attempted to define only one code, especially in EuropeUSMARC in US, Australia, Philippines, etc.

Uses of the MARC Format The MARC format enables computers to sort and file catalog data for purposes of:

printing catalog data in a variety of formats such as bibliographies

producing other products such as accession lists, shelflists, book and spine labels

producing different types of catalogs such as the OPAC

standardizing a machine-readable format for bibliographic records for exchange of

cataloging data among libraries all over the world

The MARC Record

A MARC record is composed of three elements• the record structure• the content designation • the data content of the record The record structure is derived from an international

standard for the exchange of information on magnetic tape.

The content designation comprises the codes and conventions defined by the MARC format.

The content of the data in the catalog record is created using bibliographic standards like AACR2 and the LCSH.

Fields and Tags

In a computer system, a record is a collection of related fields.

In a MARC record, a field contains either coded information (e.g., the date of entry into the system) or bibliographic information (e.g., physical description or a subject heading).

Each field has an identifying label called a tag and consists of 3 digits.

The Record Structure consists of 3 main components:• the leader • the directory• the variable fields
