What is Embedded Database?
An Embedded Database is a database that is bundled within an application. Unlike standalone databases, it is tightly integrated with the application and runs within the same process as the application itself. It’s designed primarily to be accessed by the application's code only, ensuring efficient storage, organization, and retrieval of data.
Functionality and Features
Some key features of Embedded Databases include:
- Seamless integration with application code
- Compact footprint and low memory usage
- Fast real-time data processing
- Support for SQL or other query languages
- High reliability and data integrity
Architecture
The architecture of an Embedded Database involves the coalescence of application code and database engine into a single process, ensuring a consistent, direct, and efficient interaction between the database and the application.
Benefits and Use Cases
Embedded Databases offer numerous advantages including:
- Low maintenance as they are self-contained
- Improved performance due to the removal of network latency
- Enhanced security as data does not travel across a network
Common use cases include embedded systems, mobile applications, game development, and real-time systems where speed, simplicity, and reliability are essential.
Challenges and Limitations
While Embedded Databases offer numerous advantages, they also have limitations:
- Limited scalability
- Potential for data corruption if the application crashes
- Dependency on the application for backup and recovery
Integration with Data Lakehouse
In a data lakehouse environment, Embedded Databases can play a role in real-time data processing at the edge before the data is sent to the lakehouse for further analysis. If tightly coupled with a proprietary application, an Embedded Database can ensure data integrity before it's transported to a larger analytical system, like a data lakehouse.
Security Aspects
Since an Embedded Database is bundled with the application, it's insulated from external threats that standalone databases may be exposed to. However, it is crucial to secure the application to protect the embedded database, as an application vulnerability may directly expose the database.
Performance
Embedded Databases perform faster than standalone databases in most use cases due to the absence of network latency. However, their performance might be limited by the resources of the hosting application.
