Graph analytics is becoming increasingly popular, with a deluge of new systems for graph analytics having been proposed in the past few years. These systems often start from the assumption that a new storage or query processing system is needed, in spite of graph data being often collected and stored in a relational database in the first place. In this paper, we study Vertica relational databas...

This paper proposes a parameterized definition for fuzzy comparators on complex fuzzy datatypes like fuzzy collections with conjunctive semantics and fuzzy objects. This definition and its implementation on a Fuzzy Object-Relational Database Management System (FORDBMS) provides the designer with a powerful tool to adapt the behavior of these operators to the semantics of the considered applicat...

The temporal dimension of spatial data has been the subject of discussion in the literature for a long time. While there are numerous Database Management System (DBMS) solutions only for spatial dimension, we did not observe the same situation for spatiotemporal data. Considering this gap, our purpose is to design and implement an extension to the DBMS PostgreSQL that is based on a formal spati...

The paper discusses the corpora management system (CMS) design that uses Java and Oracle9i DBMS to support strategic corpora analysis. We present the pilot webbased CMS to support linguists in their daily work. The system offers facilities to assist linguists and internet users as they search for relevant material, and then classify and annotate this material.

Although much work in the area of Active Database Management Systems (ADBMSs) has been done, it is not yet clear how the performance of an active DBMS can be evaluated systematically. In this paper, we describe the OBJECTIVE Benchmark for objectoriented ADBMSs, and present experimental results from its implementation in an active database system prototype. OBJECTIVE can be used to identify perf...

The increasing complexity of Database Management Systems (DBMSs) and the dearth of their experienced administrators make an urgent call for an Autonomic DBMS that is capable of managing and maintaining itself. In this paper, we examine the characteristics that a DBMS should have in order to be considered autonomic and assess the position of today’s commercial DBMSs such as DB2, SQL Server, and ...

In today's world, data is generated at a very rapid speed and final destination of such data is database. Data is stored in database for easy and efficient way to manage these data. All the operations of data manipulation and maintenance are done using Database Management System. Considering the importance of data in organization, it is absolutely essential to secure the data present in the dat...

This is an overview of the knowledge base management system called Kappa, one of the research and development activities performed at ICOT on databases and knowledge bases. The underlying data model is a nested relational model, and some complex data models are constructed and under consideration on the model. Deductive databases are constructed as one of knowledge base mechanisms and further e...
