DBMS Aggregation, Aggregation. In aggregation, the relation between two entities is treated as a single entity. In aggregation, relationship with its corresponding entities is aggregated into a higher level entity. For example: Center entity offers the Course entity act as a single entity in the r...
Hendevelops the concept of a semantic relationship graph to describe thenrelationships between data and then presents inference aggregation asnthe problem of finding alternative paths between vertices on the graph.nHe presents an algorithm for processing the semantic relationship graphnto discover whether ...

ing issues duplicate elimination by similarity-based clustering. The similarity relationship is expressed by language constructs, and furthermore, clustering strategies to deal with transitivity conflicts are pro- posed. In [12] Hern´ andez et. al. propose the sliding window approach for similar...
In another aspect of the present invention, the apparatus is integrated within a database management system (DBMS). The improved DBMS can be used to realize achieving a significant increase in system performance (e.g. deceased access/search time), user flexibility and ease of use. The improved...
By way of example, the “Patientinfo” table has a one-to-many relationship with the “Testresults” table. In other words, for each patient there is only one entry in the “Patientinfo” table, but there may be several entries in the “Testresults” table, since a given patient may ...
In [16], the relationship between transmission power and data reception ratio is shown. There is quite a bit of research on optimizing delay in the network layer. For example, in the shortest routing scheme, each node chooses the node closest node to the target as the next hop each time....
