Although object-oriented database systems offer more powerful modeling capability than relational database systems, their performance suffers from the increased complexity in the data model. Recently, a lot of research has been directed to mitigating this problem by building indexes over single classes, class hierarchies or nested object hierarchies. In this paper, we propose a new indexing method. It is based on the technique of signature files, but differs from the existing methods in two aspects: (1) all the signature files are organized into a hierarchy to filter irrelevant data as early as possible;(2) a signature file itself is stored as a tree structure (called a signature tree) to speed up the signature scanning. Together with the concept of query signature hierarchies, this technique reduces the search space dramatically and therefore improves significantly the time complexity of query evaluation.
In this article, we propose a method of object identification in the state of fuzzy object-oriented database schema based on different notions of fuzzy object functional dependencies. Here, fuzzy object functional dep...

The categorical relationships play a crucial role for choosing of computer database. Based on it, association rules display the link among the 2 categories. Because the objectoriented elegance for the computer code cultivates, the relationships among the categories. Additionally rise near the complicated computer code style. However, one will develop improved object-oriented style through right association rules among groups or categories. The present paper deals to style the proper association rules for the object-oriented databases taken from the categories. A true scenario of Electricity Bill Deposit System (EBDS) and user interested items by analyzing user behavior history in social network environment. Both applications are taken into account in Indian situation and Apriori Algorithmic rule is employed for locating the employment of recurrent information sets through the proper association rules. The association rules area unit deliberate through famous Unified Modeling Language. The current paper work is to the associate degree carrying out of Apriori algorithmic rule towards the information of EBDS.

The paper presents Data processing and optimization system for studying and making rational decisions on the formation of interstate electric power interconnections, with aim to increasing effectiveness of their functioning and expansion. The technologies for building and integrating a Data processing and optimization system including an object-oriented database and a predictive mathematical model for optimizing the expansion of electric power systems ORIRES, are described. The technology of collection and pre-processing of non-structured data collected from various sources and its loading to the object-oriented database, as well as processing and presentation of information in the GIS system are described. One of the approaches of graphical visualization of the results of optimization model is considered on the example of calculating the option for expansion of the South Korean electric power grid.

For enhancing the efficiency of processing users' queries, all database management systems (DBMSs) must conduct query preprocessing, or query optimizing. This paper proposes a new model for the Fuzzy object-oriented DBMS (FOO-DBMS), which optimizes the query statements and processes the data before returning back to users based on fuzzy object algebra and equivalent transformation rules. Discussions on this model are also presented with computation and analysis.
