20 Szent István University Veterinary Science Library Judit Szabó Szávay What is a database? A database is a computer readable file in which the text or other sets of data have a defined structure supperted by a set of programs called the Database Management System (DBMS)

21 Szent István University Veterinary Science Library Judit Szabó Szávay BIBLIOGRAPHIC DATABESES Bibliographic databases have developed from abstract journals, abstracting and indexing services employing computer technology. They contain: Bibliographic data Abstracts Keywords and/or other classification codes added to the records

22 Szent István University Veterinary Science Library Judit Szabó Szávay The basic structure of database Records Data fields

23 Szent István University Veterinary Science Library Judit Szabó Szávay What is a record? A record contains all the data belonging to one unit of the database. In the case of bibliographical databases, to a single publication (article) or document.

24 Szent István University Veterinary Science Library Judit Szabó Szávay What is a data field? Data fields are separate parts of a record, marked with specific names (labels). Each fields refers to a single data element. It consists of two parts: - name (label) -content Data fields are independently searchable elements in the data base.

25 Szent István University Veterinary Science Library Judit Szabó Szávay Types of the fields TI TITLE: Porcine reproductive and respiratory syndrome (PRRS) AU AUTHOR(S): Meredith-MJ AD ADDRESS OF THE AUTHOR: Department of Clinical Veterinary Medicine, Cambridge CB3 0ES, UK SO SOURCE (BIBLIOGRAPHIC CITATION):Title of Journal, 1995, 81 pp;

27 Szent István University Veterinary Science Library Judit Szabó Szávay AB ABSTRACT Much has been learned about this syndrome of multiple aetiology since it was identified in North America in the 1980’s, with subsequent spread throughout the world (by trade in pigs and boar semen). It was also known as ‘mystery swine disease’, ‘new pig disease’ and ‘blue-eared pig disease’. Current knowledge is summarized…

31 Szent István University Veterinary Science Library Judit Szabó Szávay INDEX FILES Index files or inverted files There are generated by the search software An alphabetical list of words or terms occuring in a specific data field of each record is called an index/inverted file for the given data field

32 Szent István University Veterinary Science Library Judit Szabó Szávay Author and keyword indexes An index of all author names or that of all keywords (descriptions) can be generated, together with the number of their occurances in the database, and the number of records in which they occur. For each entry in such an index, the record identifiers are also indicated in the index file.

33 Szent István University Veterinary Science Library Judit Szabó Szávay Common index file In some databases a common index file of all occuring words is generated and updated. (except for stop words, which are frequently used words which are irrelevant from the point of view of searching: „and”, „for”, „ „good”, etc.)

34 Szent István University Veterinary Science Library Judit Szabó Szávay SPIRS ( SilverPlatter Information Retrieval System) Spirs has one main index that can be displayed, plus separate indexes for: - Author (AU) - Publication year (PY) - Language (LA) You can search the main index, you can also limit for any fields

35 Szent István University Veterinary Science Library Judit Szabó Szávay Indexing for precise retrieval Indexing also means the adding of subject heading, descriptors, classification codes expressing the content of the document for which record is prepared. It is a significant process from the retrieval point of view, because

36 Szent István University Veterinary Science Library Judit Szabó Szávay Retrieval point of view It relects the most essential concepts the publications deals with, It ensures the retrieval of documents dealing with the same or related subject, and It „translates” the diverse terminology of authors to a consistent and controlled language

37 Szent István University Veterinary Science Library Judit Szabó Szávay Kids of information retrieval languages Subject categories or classification codes Usually broader categories, organised hierarchially, reflecting the logic of a discipline Subject heading lists, thesaurus (keywords, descriptors), alphabetic ordered of natural language terms Special coding systems
