摘要：A wide cast of database applications deal time-varying data. Incontrast, existing database engineering provides little supportfor managing such data. The research area of temporal databasesaims to change this state of affairs by characterizing the semanticsof temporal data and providing expressive and effcient ways tomodel, store, and query temporal data. It concisely introducesfundamental temporal database concepts, surveys state-of-the-artsolutions to challenging aspects of temporal data management.Applications such as these rely on temporal databases, whichrecord time referenced data. Temporal database management isa vibrant feld of research. Temporal Database manipulationsare effective based on life span time. This paper illustrates thegraphical representation of the temporal database manipulationsin terms of visual query with LSA. The Life Span Analyzer (LSA)provides the effective results on temporal manipulations It alsoexplains the semantics, Patterns and Visual Query Operators.
