Transactional databases: the digital gold mine

Discover the applications of transactional databases and their main characteristics.
Transactional databases are characterized by allowing a large number of short online transactions, enabling very fast query processing, maintaining data integrity in multiple access environments and guaranteeing very high levels of effectiveness . A database of this type has current and detailed information.

However, to better understand transactional databases , it is necessary to investigate some of their main characteristics:

Data source: This is operational data. OLTPs are the original source of the data.
Data purpose: The data processed is used to control and rich people database core business tasks. Transactional databases have tended to contain only the data required by the application to execute its operations, although increasingly, data about the historical context of the transaction is also captured , which can aid in subsequent analysis.
What the data contained in transactional databases reveals : a snapshot of ongoing business processes.
Inserts and Updates: Optimized for short, fast, real-time inserts and updates performed by end users.



New call to action


Queries : They can be assumed as long as they are relatively standardized and simple.
Processing speed: It is very high, requiring only milliseconds for a transactional query.
Space requirements: Transactional databases can be relatively small , if they are concerned with archiving historical data.
Design of this type of database: It is highly normalized and based on tables.
Backup and Recovery: A backup of all data should always be available , and as far as recovery options go, since this is operational data, it is critical to running your business because losing it could result in significant monetary costs and even legal liability consequences .

Applications of transactional databases
The main advantage of transactional databases is their flexibility. In them, it is possible to modify some information without having to manipulate sensitive or isolated information, since both the interface and the rules for manipulating the data memory can be achieved without changing the general structure of the system.
