SQL Query language used by users in these days based on the concept of relational algebra and relational Calculus. In these days, most Commercial RDBMSs are not providing us the platform or user interface for using Relational algebra query language. Relational algebra considered as an integral part...
In this Chapter, we consider relational databases as a data source for the generation of Linked Data, given that they constitute one of the most popular data storage media, containing huge data volumes that feed the vast majority of information systems worldwide. In this context, we review the...

OLTP code units can be written in many different programming languages, using different DBMS interfaces, and taking advantage of the numerous features of the various SQL dialects. Given this diversity, it is necessary to define a framework to properly study our relational symbolic execution approach....
Periodic data play a major role in many application domains, spanning from manufacturing to office automation, from scheduling to data broadcasting. In man
Let us first give an overview of the life of a SQL query inside a compiling DBMS, using the system Umbra as an example. A query is parsed to an abstract syntax tree, which is then semantically analyzed and translated to relational algebra. The query optimizer takes the relational algebra tr...
Versions Notes Abstract The way a database schema is designed has a high impact on its performance in relational databases, which are symmetric in nature. While the problem of schema optimization is even more significant for NoSQL (“Not only SQL”) databases, existing modeling tools for relatio...
