Set of DBMSs/interfaces/tools/facilities which manage/provide access
to enterprise-wide data. Includes EDA/SQL Server which processes SQL
requests against relational and non-relational data, API/SQL call
level API, EDA/Link modular system of communication interfaces and
EDA/Extender Products which are direct interfaces which allow many
existing products immediate entry to Information Warehouse framework.Îïèñàíèå-Ò
Client/server programs designed to work together to provide SQL-based
access to relational and nonrelational data on interconnected
multivendor systems. Provides transparent access to over 45
relational and nonrelational databases and files from PCs,
workstations and nonprogrammable terminals. Generates SQL requests
for data upon each user's request and transparently distributes and
processes the requests against local or remote data and returns the
desired results directly to the user. Allows users to join similar or
dissimilar relational and nonrelational databases and files and update
relational databases. Includes a call level API (API/SQL) that allows
3GL applications to send and receive SQL requests from anywhere in the
enterprise. Supports central storage and cataloging of procedures,
each of which may consist of SQL statements, environmental setups or
other programs, allowing them to be executed by any local or remote
application. Provides centralized data definitions and security
management and may grant or revoke access privileges to any local or
remote data supported. Features an EDA/Link system of communications
interfaces that ensure proper protocol conversion and create outgoing
packets for the client, route the packets to the server and route the
answer set packets to the appropriate client. The EDA/SQL Server
component acts as a process director and manages the flow of data,
keeping track of incoming requests and outgoing responses.ÒÅÐÌÈÍÛ
