METU Interoperable DBMS (MIND) is a multidatabase system based on OMG's distributed object management architecture. It is implemented on top of a CORBA compliant ORB, namely, DEC's ObjectBroker. In MIND, all local databases are encapsulated in a generic database object. The interface of the generic database object is defined in CORBA IDL and multiple implementations of this interface, one for each component DBMS, namely Sybase, Adabas D and MOOD are provided. MIND provides its users with a common data model and a single global query language based on SQL. The main components of MIND are a global query manager, a global transaction manager, a schema integrator, interfaces to supported database systems and a graphical user interface. The integration of export schemas is currently performed by using an object definition language (ODL) which is based on OMG's interface definition language. MIND global query optimizer aims at maximizing the parallel execution of the intersite operations of the global subqueries. Through the MIND global transaction manager, the serializable execution of the global transactions (both nested and flat) is provided.

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 generalized expert system for database design Doğaç, Asuman; Yürüten, Betigül; Spaccapietra, Stefano (Institute of Electrical and Electronics Engineers (IEEE), 1989-4) 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...
Kinematic design of mechanisms in a computer aided design environment Demir, Eralp; Söylemez, Eres; Department of Mechanical Engineering (2005) CADSYN (Computer Aided Design SYNthesis) is a visual, interactive computer program working under Computer Aided Design (CAD) enviroment, which accomplishes the synthesis and analysis of planar four-bar mechanisms. The synthesis tasks are motion generation, path generation and function generation. During synthesis, the dyadic approach is utilized which introduces vector pairs and complex number algebra to model the motion. The possible solutions can be limited for link dimensions, the center circle point cur...
HyGraph: a subgraph isomorphism algorithm for efficiently querying big graph databases Asiler, Merve; Yazıcı, Adnan; George, Roy (2022-04-01) The big graph database provides strong modeling capabilities and efficient querying for complex applications. Subgraph isomorphism which finds exact matches of a query graph in the database efficiently, is a challenging problem. Current subgraph isomorphism approaches mostly are based on the pruning strategy proposed by Ullmann. These techniques have two significant drawbacks- first, they are unable to efficiently handle complex queries, and second, their implementations need the large indexes that require ...
