HSPD Summary: The HSPD suffers from the various limitations inherent in the use of a DBMS for information management. Relational databases are structured with a presumption that the user has a knowledge of the language of the subject field and a grasp of the set intersection techniques that are required to effectively query the database and retrieve desired information. Without the specification of appropriate query sets using valid key words, a DBMS system such as dBASE has little practical utility. The dBASE software is capable of synonym recognition which can enhance information retrieval performance. However, a search operation will ignore data fields that may closely match search criteria but do not include the key word specified in the user query. A significant handicap represented by this method of data retrieval is that dBASE and other DBMS software do not communicate to the user a sense of the structural relationships between the information fields contained in the knowledge base. A skillful dBASE user can retrieve information that matches search criteria, and yet not only fail to access all the data relevant to the search (if the system ignores close fits), but also fail to comprehend the patterns of information that are the foundation of knowledge. This failing of DBMS applications can be attributed to the fact that the system is structured according to individual words rather than ideas. Evaluation Criteria HSPD HSPD: Attributes 1.
