![]() The Digital Object Identifier (DOI) is a comparatively new parameter, which describes the distinctive placement of a document on the Web. Typical fields in bibliographic records are – author, article title, journal name, volume, issue, year of publishing, pages, etc. The bibliographic databases usually do not have the full text of a document, however it records information about a single publication, patents, and similar documents. Structured databases are generally classified into two large groups in terms of its contents as bibliographic and factographic. The Chemical Abstracts Service Registry Number (CAS RN) is an example of the primary key for the structure in the REGISTRY database. ![]() Each record is always assigned a unique “ID” or “Number” called as identifier or the primary keys, which are easily referenced. On the other hand, structured databases normally include a set of tables that contain records or rows, all of which have the same structure well defined by a set of fields or columns. The largest database of this type on this globe is definitely operated by Google, in which documents and other accessible files are uploaded on the internet in the form of websites. This type of database is commonly run by publishers of magazines and books, patent offices for patents or academic institutions. Ī full-text database is generally a set of documents in which indexes are created to facilitate their fast search. full-text and the structures, based on the category of data contained. The databases are broadly distributed in two major group’s viz. It is must to have a better understanding of how the data is organized and interconnected for the effective search in any database. ![]() Therefore, the computer supported databases are becoming useful tools for several research laboratories in industry as well as in academia. The proficiency of search algorithms executed within these databases are very crucial. The dimension of all databases either in terms of the structures or that of the reactions are growing tremendously each year. Accessing chemical information that are stored in different kinds of databases by utilizing the means of computer are gradually becoming more significant. Chemical databases have now become a powerful tool in drug discovery.ĭatabase searches based on potential requirements for biological activity identifies compounds that are suitable for detailed analysis or indicate novel ways to achieve the desired activity. In addition to the basic search techniques that are used today in almost everyday life, such as searching by keyword search engines, there are some areas of chemistry that are not so simple or meaningful. A database is an organized collection of data in any field. This vast information data must be systematically organized by the experts in the field. Chemistry is an interdisciplinary subject upon which the other scientific disciplines are dependent to a certain extent. The abundance of technological and Internet resources can both simplify and complicate a researcher’s world. The amount of information available today is growing at an exponential rate and the ability to search for the necessary information is one of the basic needs of knowledge. Thus, substance and citation databases that covers almost all areas of chemistry, has become an invaluable tool in bibliometric analysis. It also gives a brief description of three major commercial databases such as Scopus, Web of Science, and SciFinder. This paper provides an overview of the most frequently used free chemistry databases such as PubChem, Crystallography Open Database, PubMed, ZINC, ChemSpider, and Google Scholar. The benefits that databases can provide in the preparation of the literature review for developing future studies and dissemination of research are discussed. If a library can only afford one, choice must be based on the priorities of institutional needs. ![]() None of the databases are complete and perfect, but they complement each other. This review offers information on the important points of the database. Make Better Decisions with DrugPatentWatchĪs scientific community worldwide is publishing a huge number of research articles in various fields it is necessary to distinguish between databases that are efficient and objective for literature searches. ![]()
