What is an Operational Database?
An Operational Database, also known as an Online Transaction Processing (OLTP) Database, is a database system designed to manage dynamic data in real-time. It is frequently employed in sectors like banking, retail, and telecommunications, where immediate processing and storing of transactions is essential.
Functionality and Features
Operational Databases enable simultaneous data processing and updating, primarily supporting Create, Read, Update, and Delete (CRUD) operations. The main features of operational databases include:
- Data Consistency: Ensures that data remains consistent during and after transactions.
- Concurrency Control: Allows multiple users to access data without conflict.
- Atomicity: Ensures all operations in a transaction are completed successfully or none at all.
Architecture
The architecture of an operational database is structured such that it can handle multitudinous transactions swiftly. This database usually employs a row-based relational model that allows quick data modification and transactional integrity.
Benefits and Use Cases
Operational databases offer several benefits:
- Real-time Processing: They provide instant data access, enabling swift decision making.
- Improved Productivity: They streamline operations by automating routine tasks.
- Enhanced Customer Experience: By providing real-time data, they can help improve customer support and service.
Challenges and Limitations
Despite their advantages, Operational Databases have limitations, including their inability to handle vast amounts of data storage and complex queries efficiently.
Integration with Data Lakehouse
In the context of a data lakehouse, Operational Databases can serve as sources of data ingestion. As the data lakehouse aims to unify disparate data sources, Operational Databases' data can be ingested, processed, and made available for advanced analytics in a data lakehouse environment.
Security Aspects
Operational Databases incorporate various security measures, like access controls, encryption, and backup strategies, to safeguard sensitive transactional data.
Performance
The performance of Operational Databases is critical as they need to process transactions rapidly. They are optimized for write-heavy workloads and short, fast queries.
