Database Management Systems: A database organizes information in a system of records and fields. The records represent the primary level of data classification, reflecting the general taxonomy or theme of the database (Robie, 1988). For instance, a resource database for a national park might contain records which comprehensively describe each individual park building or structure. Each building record is comprised of numerous data fields which contain specific information concerning the particular traits or qualities that are relevant in characterizing the individual structures. The database fields describe a variety of site or building components and materials, knowledge of which is essential to the management of the resource. In a DBMS, the records and fields are manipulated through a query process that seeks specific information from the database by defining particular parameters for data retrieval. The database is searched according to the specified qualifiers, and only that information which matches those conditions is retrieved from the data records.
