CDS/ISIS PRACTICAL SESSION
The Department of library, Archival and Information Studies (LARIS) librarian, Emeaghara, N. Evelyn (Mrs.) had a practical session on CDS/ISIS with LARIS post graduate student (MLIS I).
Computerized Documentation System/Integrated Set of Information System (CDS/ISIS) is an information management system dealing with predominantly non-numerical data elements, which are stored in database. CDS/ISIS was developed by United Nations Education Scientific and Cultural Organization (UNESCO).
The CDS/ISIS version 1.4 software package is used in LARIS Departmental Library and WEDLIS is the most recent version of CDS/ISIS. It has search modules, data entry modules, print enabled and import enabled. CDS/ISIS have many distinctive features which gives you more control over the way you work as well as enabling you to use more of the power of the computer.
It allows you to have more than one CDS/ISIS database open.
CDS/ISIS was developed for bibliographic information, i.e. information about documents such as books, journal articles or conference proceedings. Titles of books and other works which are contained in a bibliographic record may be of any length, from one word to many. CDS/ISIS is protected by copyright and is in no way shareware or public domain. It can be used legally only by license holders. This license is not as restrictive as some commercially produced software packages, in that multiple copying of the software is permitted within an institution that is a license holder. UNESCO has appointed distributors throughout the world to assist in supplying it to those who wish to use it.
CDS/ISIS software is made up of files, which contain elementary data elements that could be defined and manipulated in various was such as: define databases worksheet entry, enter new record, modify-correct and delete records, automatically build and maintain fast access files to each database, retrieve records, sort records, display the records, print catalogues and indexes.CDS/ISIS uses inverted files to enable faster searching of the database. An inverted file is just another name for an index. It is possible to index each field in a number of ways using different indexing techniques. The expression refers to the fact that the records are turned inside out to bring different elements from the contents to the fore in a file.
CREATING A DATABASE
A database is usually constructed to store information about some things or persons. For example, a bibliographic database contains information about documents, such as journal articles or conference proceedings. The database consists of records and there is generally a one-to-one correspondence between the records and the things described. A record is made up of a number of fields. Each field contains data about some particular aspects. For example, the author, title and date in a bibliographic database.
• Choice of Tagging Scheme: Decide on a format, i.e. what fields will b used and how you will record the data in them.
• Field Definition Table: It defines the fields that may be present in the database and certain parameters for each field.
• Default Display Format: Means the way that the records will appear when you display search results. It can also be used in producing printed output.
• Field Selection Table: the selection of terms from the database records to go on to index file is controlled by the field selection table.
• Stopword List: Words on the stopword list will not be indexed using indexing techniques (though they may still appear as part of phrases produced with other indexing techniques).
• Choice of Indexing Technique
• Database Parameter File: When a database is created, the system places it automatically in the data subfolder.
• Database EXP File: In this display the screen is divided into two panels, the left one containing a list of record numbers and right one containing some tips on how to use the display window.
