A short summary of the two panel discussions is also included. The volume is intended to be a reflection of the current state of knowledge and a guide to further development in database theory. The main topics covered are: theoretical fundaments of the relational data model (dependency theory, design theory, null values, query processing, complexity theory), and of its extensions (graphical representations, NF2-models), conceptual modelling of distributed database management systems and the relationship between logic and databases.Lecture Notes in Computer Science,0302-9743 ;305ComputersData structures (Computer science)Theory of Computationhttps://scigraph.springernature.com/ontologies/product-market-codes/I16005Data Structures and Information Theoryhttps://scigraph.springernature.com/ontologies/product-market-codes/I15009Models and Principleshttps://scigraph.springernature.com/ontologies/product-market-codes/I18016Computers.Data structures (Computer science).Theory of Computation.Data Structures and Information Theory.Models and Principles.005.74/01/51Biskup Joachimedthttp://id.loc.gov/vocabulary/relators/edtDemetrovics Janosedthttp://id.loc.gov/vocabulary/relators/edtParedaens Janedthttp://id.loc.gov/vocabulary/relators/edtThalheim Bernhardedthttp://id.loc.gov/vocabulary/relators/edtSymposium on Mathematical Fundamentals of Database SystemsBOOK996465815303316MFDBS 872831514UNISA
