OBDA Over Non-Relational Databases
The database landscape has been significantly diversified during the last decade, resulting in the emergence of a variety of non-relational (also called NoSQL) databases, e.g., XML and JSON-document databases, key-value stores, and graph databases. To facilitate access to such databases and to enable data integration of non-relational data sources, we generalize the well-known ontologybased dat...
متن کاملTowards the Object Persistence via Relational Databases
Object-oriented (OO) databases have happened important for both research and development area in the past decade. On the other hand, databases of this type have been found too expansive and not too functional in a planty of practical tasks. New architectures appeared: object-relational data managers, relational wrapper libraries, and OO databases. The attractiveness of these solutions is that e...
متن کاملTowards Quadtree-Based Moving Objects Databases
Nowadays, one of the main research issues of great interest is the efficient tracking of mobile objects that enables the effective answering of spatiotemporal queries. This line of research is relevant to a number of modern applications spanning many contexts. In this paper, we consider the organization of a moving object database by quadtree based structures (structures obeying the Embedding S...
متن کاملRelational Databases Query Optimization using Hybrid Evolutionary Algorithm
Optimizing the database queries is one of hard research problems. Exhaustive search techniques like dynamic programming is suitable for queries with a few relations, but by increasing the number of relations in query, much use of memory and processing is needed, and the use of these methods is not suitable, so we have to use random and evolutionary methods. The use of evolutionary methods, beca...
متن کاملConverting Relational Databases into Object-relational Databases
ion (abs): A super-class is abstract (i.e., abs := true) when all of its objects are members of its sub-type objects. Instances of an abstract type cannot appear in the database extension, but are subsumed into instances of its sub-types. Attributes (Acdm): A class C has a set of attributes Acdm. Acdm := {a | a := 〈an, t, tag, l, n, d〉}, where each attribute a has a name an, data type t and a t...
