Business users depend on having easy access to trustworthy, complete data. But data integration is no easy task, because data is spread across disparate systems and data volumes are rapidly increasing.Data Integration is a simple, flexible solution that addresses data integration challenges for small and midsize businesses. It ensures data credibility and consistency – so organiza¬tions can easily manage all their data integration projects while reducing costs and increasing overall productivity.
Access all data management activity from a single, common control point.
Secure role-based access and actions to authorization for specific data quality tasks.
Avoid logging in to a different web page or panel when moving from one function of the data management platform to another.
Master Data Management Foundation
Integrate the creation and management of master data resources with comprehensive data management practices.
Create a hub of master data based on a subset of your existing data, using a phased approach.
Combine MDM capabilities with matching, clustering and other data management initiatives.
Conduct batch processing with an architecture that supports many MDM implementations without unnecessary complexity.
Connect to MDM hubs as if they were any other data target.
Embed data quality into extract, transform and load (ETL) and extract, load and transform (ELT) activities from multiple sources using both traditional batch processing and in-database methods.
Data integration. Embed data quality into extract, transform and load (ETL) and extract, load and transform (ELT) activities from multiple sources.
Data Integration Techniques
There are several organizational levels on which the integration can be performed. As we go down the level of automated integration increases.
Middleware Data Integration - transfers the integration logic from particular applications to a new middleware layer. Although the integration logic is not implemented in the applications anymore, there is still a need for the applications to partially participate in the data integration.
Uniform Data Access or Virtual Integration - leaves data in the source systems and defines a set of views to provide and access the unified view to the customer across whole enterprise.
For example, when a user accesses the customer information, the particular details of the customer are transparently acquired from the respective system.
The main benefits of the virtual integration are nearly zero latency of the data updates propagation from the source system to the consolidated view, no need for separate store for the consolidated data.
However, the drawbacks include limited possibility of data's history and version management, limitation to apply the method only to 'similar’ data sources (e.g. same type of database) and the fact that the access to the user data generates extra load on the source systems which may not have been designed to accommodate.
Common Data Storage or Physical Data Integration - usually means creating a new system which keeps a copy of the data from the source systems to store and manage it independently of the original system.
The most well know example of this approach is called Data Warehouse (DW). The benefits comprise data version management, combining data from very different sources (mainframes, databases, flat files, etc.). The physical integration, however, requires a separate system to handle the vast volumes of data.
