Ensuring data accuracy through integrity constraints is a central aspect of DBMS use. However, many DBMSs still lack adequate integrity support. In addition, a comprehensive theoretical basis for such support—the role of a constraint classification system—has yet to be developed. This paper ...
Deep learning natural language processing (NLP) models have revolutionized information retrieval, making semantic-aware searches accessible even to those without specialized knowledge in a particular field. These models operate through complex neural networks, which enable them to understand the nuances of ...

In what follows, we introduce two scenarios to motivate our work. Both examples involve Apache Derby,4 an open source DBMS implemented entirely in Java and is often embedded in other projects to support online transaction processing. Scenario#1: Missing knowledge integration. A significant body of ...
However, most of the geospatial data remain in various geographic formats (e.g., ESRI Shapefiles [5]) or DBMSs (e.g., Oracle Spatial [6] or PostGIS [7]) while utility regulations are typically textual documents. Due to a lack of unified standards in the utility domain, data sharing ...
Besides their use in external schemas, views are useful for ensuring data security in a simple way if users may only access the database through views, they cannot see or manipulate the hidden data, which are therefore secure. In a distributed DBMS, a view can be derived from distribut...
The package DELETE consists of several functions allowing to delete single or multiple city objects from the database according to the given row ID or an object class ID in the CITYOBJECT table. Each function automatically takes care of the integrity constraints between the related tables to ...
So semantic and data relations are managed by the same DBMS and accessed by the same query language. SDM is based on conceptual graphs encompassing simple and structured entity types, relationship types, and includes type hierarchy and integrity constraints specification. Structured entities represent ...
Semantic query simplification utilizes integrity constraints enforcedin a database system for reducing the number of tuple variables andterms in a relational calculus query. To a large degree, this can bedone by a system that is external to the DBMS. The paper advocatesthe application of database...
