Resident database interfaces to the DAVID system, a heterogeneous distributed database management system

A methodology for building interfaces of resident database management systems to a heterogeneous distributed database management system under development at NASA, the DAVID system, was developed. The feasibility of that methodology was demonstrated by construction of the software necessary to perform the interface task. The interface terminology developed in the course of this research is presented. The work performed and the results are summarized

Component Approach to Software Development for Distributed Multi-Database System

The paper deals with a component based approach for software development in a distributed environment for the database retrieval operations. A Core Component for a distributed multi-database system has been proposed. The core Component is modeled using three interfaces User, Administrator and Databases Handler. The User Interface is the starting point of access for the Core Component. The Administrator interface deals with access control privileges for users and local databases. The Database Handler facilitates global schema management and site management.Assertion, Core Component, Component Based Software Development, Multi-Database, Schema

Tools for distributed application management

Distributed application management consists of monitoring and controlling an application as it executes in a distributed environment. It encompasses such activities as configuration, initialization, performance monitoring, resource scheduling, and failure response. The Meta system (a collection of tools for constructing distributed application management software) is described. Meta provides the mechanism, while the programmer specifies the policy for application management. The policy is manifested as a control program which is a soft real-time reactive program. The underlying application is instrumented with a variety of built-in and user-defined sensors and actuators. These define the interface between the control program and the application. The control program also has access to a database describing the structure of the application and the characteristics of its environment. Some of the more difficult problems for application management occur when preexisting, nondistributed programs are integrated into a distributed application for which they may not have been intended. Meta allows management functions to be retrofitted to such programs with a minimum of effort

The Design of a Distributed Database for Doctoral Studies Management

This paper aims to create a system that manages doctoral school requirements. The management of doctoral school implies administration of information like PhD personal information, Supervisors, Teachers, and other information that may be useful. We will debate on distributed database term as the proposed database project will have the same structure for four universities. Each university will be able to work on this database by accessing its own set of data and properly using the information received. This project will track the creation of a database to manage all the information needed and provide answers using these data.Distributed Database, Fragmentation, Top-Down Design Process

Interface between astrophysical datasets and distributed database management systems (DAVID)

This is a status report on the progress of the DAVID (Distributed Access View Integrated Database Management System) project being carried out at Louisiana State University, Baton Rouge, Louisiana. The objective is to implement an interface between Astrophysical datasets and DAVID. Discussed are design details and implementation specifics between DAVID and astrophysical datasets

Basis Data Terdistribusi Untuk Data Inventaris Barang

A system can not be separated from the database. The database can either be petrified management in data processing in a rapid, precise and accurate . One of distributed database is one of 3 types of databases that can be used apart from the type of relational database, database integration. For a company that has many branches of the need for a database that can hold large amounts of data with very necessary , a distributed database is appropriate for the management of data bases that can be used in several branches of the company. This research will discuss a distributed database system for managing data inventory. So the data inventory at each branch can be distributed and reported quickly and efficiently.
