Present study investigated particularly dynamic data replication technique and its realization between analogous database and heterogeneous database mainly based on the most popular large commercial database Oracle and SQL Server.
With a large amount of data represented in XML documents on Web,it becomes necessary to store and query XML,and now,nearly all commercial database products have supported to store,query,and retrieve XML documents.
As a new technology to process business information, data mining can extract, transfer, analysis and modulate the mass data in the business database, to get the key data helpful to business decision and help enterprises to be intelligent in management.
If we have a fund research and analysis platform which is established based onself-database, the former problems can be solved easily. The data of self-database is basedon business database, at the same time, according to data which is collected by the analyst,we can update and increase the self-database.
Adaptive data access mechanism is that construct its own data type, data model and data dictionary based on the different databases and access database by appropriate data access engine based on friendly interface.
This was accomplished by creating a synthetic spectrum for the species being studied (CH4, N2O, CO2 and H2O in ambient air) utilizing line positions and linewidths with an assumed Voigt profile from a commercial database (HITRAN).
Current commercial database management systems provide various means to implement mechanisms to enforce semantic integrity constraints at database run-time.
The relational tables thus obtained were implemented on a commercial Database Management System (DBMS).
We have run extensive experiments with PowerDB-IR using several commercial database systems as well as different middleware products.
These included client-side approaches, server-side approaches, simple e-mail-based systems, Java-based systems, systems based on the Common Gateway Interface (CGI), and commercial database systems.
Comparison of national administrative and commercial databases to monitor expenditure and costs of statins across Europe
This knowledge was used to search commercial databases.
These benefits are investigated by applying discretisation algorithms to two large commercial databases; the discretisations yielded are then evaluated using a simulated annealing based data mining algorithm.
Motivated by the way R-trees are implemented in commercial databases systems, in this paper we examine several deletion techniques for R-trees.
We investigate a number of measures of feature subset quality, usinglarge commercial databases.
Drawing upon data from the authors' Vietnamese Business Database that covers information between 1983 and 2003, we present both spatial and temporal analyses that offer insights into how the Vietnamese businesses grow through time.

For example, converting business articles to a structured business database.
It is useful in implementing an integrated design for an entire business database including the geodatabase components.
This paper presents a new data model ( DB-GEOMOD ) to manage the geometrical data and the non-geometrical data in engineering data base environment.Representing the geometrical data in NET/RELATION hybrid model, we can manage the geometrical and non-geometrical data in the same way. In this case, the paper presents an idea to integrate the geometrical and nongeometrical data in data base enviroument.
