There are many problems facing scientists in their efforts to use computers to manage, access, and analyze data. One serious problem is the heterogeneity of data sources. Previous research into accessing heterogeneous data has not addressed problems with accessing large data sources that are not managed by database management systems. We believe that an object-oriented database management system can be used to implement an object-oriented heterogeneous database (OOHDB) that efficiently addresses the problem of heterogeneity among large scientific property databases. The object-oriented data model provides a powerful modeling paradigm for representing complex scientific data. objects within the OOHDB hide heterogeneity among various data sources. Efficient access to external data is achieved by representing external data with a small amount of data stored within the OOHDB.< >

Concurrency control has been thoroughly studied in the context of traditional database applications such as banking and airline reservations systems. There are relatively few studies, however, that address the concurrency control issues of advanced database applications such as CAD CAM and software development environments. The concurrency control requirements in such applications are different from those in conventional database applications;in particular, there is a need to support nonserializable cooperation among users whose transactions are long-lived and interactive and to integrate concurrency control mechanisms with version and configuration control. This paper outlines the characteristics of data and operations in some advanced database applications, discusses their concurrency control requirements, and surveys the mechanisms proposed to address these requirements.

Advanced applications in fields like electronic publishing and telecooperation face the problem of handling multimedia information. Conventional database systems do not offer adequate support for storage management as they do not provide for the modeling, indexing, and manipulation of multimedia data. Database management systems need to be extended if they should be able to handle multimedia information like audio and video. In this paper we present an approach of extending the data model of an object-oriented database system by means of schedules which allow for the description of the temporal characteristics of multimedia operations as they occur when modeling time-dependent data like audio and video. First, we present a model of schedules and define the basic concepts and semantics to execute time-dependent operations. Second, we introduce the specification language as an extension to the VODAK Model Language and illustrate the concepts by examples. Finally, we briefly discuss the impact of integrating multimedia data modeling support into a database management system on the system architecture.< >

ALCHEMIST is a general purpose object-oriented transformation generator. ALCHEMIST provides a new approach to developing transformations between any well-defined representations. It allows users to define the syntactic structure of the data representations and the related structure associations with a grammar notation. These grammars can then be augmented with semantic operations. From this description a persistent object-oriented representation is formed and a transformation module is generated automatically. This transformation module relies on an object representation of the parse tree. The principles underlying ALCHEMIST are discussed and its object-oriented design decisions are described.< >

A Federated Information System requires that multiple (often heterogenous) information systems are integrated to the extent that they can share data through views. One issue faced during the construction of federated view schemata is the continuous need to extract metadata from cooperating systems. This is more pressing in the case of federated multimedia systems where needless transfer of large binary objects affects system performance. Where participating systems employ an object-oriented common model to communicate, obtaining metadata is problematic due to the type and complexity of object-oriented metamodels. In the IOMPAR project, we specified and developed a high-level query interface for the ODMG schema repository in order to simplify this task for integration system engineers. This paper describes a schema repository query language which greatly reduces the efforts of integration engineers.

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.
