The Use of a Metadata Repository in Spatial Database Development
Database schemas currently used to define spatial databases are deficient in that they do not incorporate facilities to specify business rules/integrity constraints. This shortcoming has been noted by Gnther and Lamberts [Gnther & Lamberts, 1994] who commented that geographical information systems (GIS) do not generally offer any functionality to preserve semantic integrity. It is desirable t...

متن کاملA metadata approach to multimedia database federations
Recent research in federated database systems has advanced in the direction of federations of multimedia databases. However, in each project studied, there has been little emphasis placed on the subject of meta-models. Conversely, standard database systems (relational, object-relational and object-oriented) define metadata models that lack multimedia and federation features. In this paper, a sp...
متن کاملMetaData for Database Mining
At present, a machine learning application is accomplished by carefully crafting a single table from an often complex, multi-table database. The metadata necessary to create this table is rarely formally recorded, and is sometimes implicit in the structure of the database or the typing of the attributes. We categorize the types of metadata that we have encountered in our work with machine learn...
متن کاملAssembling Metadata for Database Forensics
Since information is often a primary target in a computer crime, organizations that store their information in database management systems (DBMSs) must develop a capability to perform database forensics. This paper describes a database forensic method that transforms a DBMS into the required state for a database forensic investigation. The method segments a DBMS into four abstract layers that s...
