Drug Information Storage and Retrieval
Data storage and retrieval refers to the process of collecting, cataloguing, and retrieving data in order to display and retrieve it when called for. Government, commercial, and academic organizations can now retrieve large amounts of information quickly and selectively thanks to computers and data processing technologies. Retrieval and storage systems can be categorized according to their functionality. The systems that retrieve whole documents usually retrieve them by their titles or by keywords associated with them.Documents are sometimes stored as data in some systems. By doing so, you can search for text within a document, retrieving information based on any words contained in it. Some collections are stored as digitized images, usually on optical discs that are write-once. A database system stores information in discrete records with discrete fields (e.g., names, addresses, and phone numbers); records can be searched and retrieved based on their contents (e.g., all people with a certain phone area code). Within the computer, data is stored either in main storage or in auxiliary storage, allowing it to be easily accessed.
The computer provides us with powerful tools for managing information - for collecting, organizing, categorizing, retrieving and distributing it. The early 1960s saw the first large-scale database on computers, such as library catalogues and bibliographic references. We are able to store large amounts of text, graphics, pictures, and sound for a low price due to the development of optical storage media, such as CD-ROM. With this new technology, encyclopedias, databases, books and dictionaries can be stored on optical memories. As a result of this development, local information systems have been developed.
Database Types
Databases can be categorized into the following types:- Library catalogues - Catalogs containing descriptions of the holdings (books, reports, journals, conference proceedings, etc.) of a library or libraries.
- Full-text database - A full-text database contains the complete text of a given publication.
- Factual databases - A database or data bank of facts that contains information, often in numerical form, from which you can draw conclusions, e.g., chemical structure, table, terminology.
- Bibliographic databases - Reference databases that provide references, including abstracts.
- Reference database - Examples of reference databases would be current research projects, product suppliers, handbooks, encyclopedias, etc.
