A.3.4 Integrated Database Systems Notes
Integrated database systems are designed to combine data from multiple sources into a single, unified view.
This approach allows organizations to access, manage, and analyze data from different databases and applications seamlessly.
Note
Integrated database systems are often used in large organizations where data is stored in multiple departments or locations.
Key Components
Data Integration Tools:
These tools extract data from various sources, transform it into a consistent format, and load it into a central repository.
This process is known as Extract, Transform, Load (ETL).
Middleware acts as a bridgebetween different databases and applications, enabling them to communicate and share data.
Data Virtualization:
This technology allows users to access and query data from multiple sources without physically moving the data.
It creates a virtuallayer that provides a unified view of the data.
Integrated Database Systems Functionality
Data Extraction: Data is extracted from various sources, such as relational databases, flat files, and cloud applications.
Data Transformation: The extracted data is transformed into a consistent format, ensuring compatibility across different sources.
Data Loading: The transformed data is loaded into a central repository, such as a data warehouse.

Introduction to Integrated Database Systems

DefinitionIntegrated Database SystemA system that combines data from multiple sources into a single, unified view, allowing seamless access, management, and analysis of data.
AnalogyThink of an integrated database system like a universal remote control that can operate all your electronic devices. Instead of using separate remotes for your TV, DVD player, and sound system, you have one remote that controls everything. Similarly, an integrated database system provides a single interface to access data from multiple sources.
