In this paper, we propose an efficient technique to statically manage integrity constraints in object-oriented database programming languages. We place ourselves in the context of an extended version of the O2database programming language, and we assume that updates are undertaken by means of methods...
The problem of Integrity Constraints checking in the area of Logic Databases is considered and some research results are presented in which the notion of View Constraints as restriction on a database emerges. This notion is presented and compared with the general notion of Integrity Constraints. Som...

In the data model I'm creating, all of the tables, primary and foreign keys, unique constraints, validation rules etc. are defined using a combination of inline SQL (for DDL) and VBA. The only thing that's missing is how to set the properties of the foreign key. Access gives a run-...
However, the resource-constrained architecture of IoT has always been the main hindrance in integrating IoT with the blockchain, since the consensus algorithms have to be limited to work within these constraints. Some current works deploy heavy consensus algorithms on other devices that are part of...

Referential Integrity Constraints in DBMS with DBMS Overview, DBMS vs Files System, Architecture, Three schema Architecture, Language, Keys, Generalization, Specialization, Relational Model concept etc.
In the chart we have identified operating systems, the database management system (DBMS), the teleprocessing monitor (1P monitor), compilers, utilities and access control software as representative of this class. The proper functioning of the whole system is dependent on the proper functioning of ...
INTRODUCTION Consistency, or data integrity, in databases is usually achieved by associat- ing with each database a set of constraints. The database management system (DBMS) has the responsibility to ensure that these constraints are satisfied by the database state at all times. Generally, this ...
