Generalized Expert System for Database Design (GESDD) is a compound expert system made up of two parts: (1) an expert system for generating methodologies for database design, called ESGM; and (2) an expert system for database design, called ESDD. ESGM provides a tool for the database design expert to specify different design methodologies or to modify existing ones. The database designer uses ESDD in conjunction with one of these methodologies to design a database starting from the requirement specification phase and producing a logical schema in one of the well-known data models, namely, the hierarchical data model, the network data model, or the relational data model. The system is evolutive in the sense that an existing methodology can be modified or a novel methodology can be added to the existing ones. GESDD is a menu-driven system and it is coded in Prolog.< >

Using fuzzy Petri nets for static analysis of rule-bases
Bostan-Korpeoglu, B; Yazıcı, Adnan (2004-01-01)
We use a Fuzzy Petri Net (FPN) structure to represent knowledge and model the behavior in our intelligent object-oriented database environment, which integrates fuzzy, active and deductive rules with database objects. However, the behavior of a system can be unpredictable due to the rules triggering or untriggering each other (non-termination). Intermediate and final database states may also differ according to the order of rule executions (non-confluence). In order to foresee and solve problematic behavior...
A new hybrid multi-relational data mining technique
Toprak, Seda Dağlar; Toroslu, İ. Hakkı; Department of Computer Engineering (2005)
Multi-relational learning has become popular due to the limitations of propositional problem definition in structured domains and the tendency of storing data in relational databases. As patterns involve multiple relations, the search space of possible hypotheses becomes intractably complex. Many relational knowledge discovery systems have been developed employing various search strategies, search heuristics and pattern language limitations in order to cope with the complexity of hypothesis space. In this w...
An Evolutionary Genetic Algorithm for Optimization of Distributed Database Queries
Sevinc, Ender; Coşar, Ahmet (2011-05-01)
High-performance low-cost PC hardware and high-speed LAN/WAN technologies make distributed database (DDB) systems an attractive research area where query optimization and DDB design are the two important and related problems. Since dynamic programming is not feasible for optimizing queries in a DDB, we propose a new genetic algorithm (GA)-based query optimizer (new genetic algorithm (NGA)) and compare its performance with random and optimal (exhaustive) algorithms. We perform experiments on a synthetic data...
An attempt to classify Turkish district data : K-Means and Self-Organizing Map (SOM) algorithms
Aksoy, Ece; Işık, Oğuz; Department of Geodetic and Geographical Information Technologies (2004)
There is no universally applicable clustering technique in discovering the variety of structures display in data sets. Also, a single algorithm or approach is not adequate to solve every clustering problem. There are many methods available, the criteria used differ and hence different classifications may be obtained for the same data. While larger and larger amounts of data are collected and stored in databases, there is increasing the need for efficient and effective analysis methods. Grouping or classific...
A comparative evaluation of XML repositories
Ünal, Özgül; Doğaç, Asuman; Department of Information Systems (2002)
Recently XML has established itself as the standard for representing data in scientific and business applications. Starting out as a standard data exchange format over the web, it has become instrumental in all kinds of applications. Almost all standardization efforts on the web today are based on XML. As a consequence, the amount of XML data being stored and processed is large and will be increasing at a very rapid rate. This has caused XML data management to become a focus of research efforts in the datab...
