Database testing is one of the most important parts of database administration. Just like any other application or software, regular testing is required to ensure that your databases are in great shape – and that they are free of potentially serious errors and faults that could cause data loss, improper data entry, and more.
In this article, we’ll go over just a few of the reasons that it’s so important for you to test your database. Let’s get started now.
1. To Verify Proper Data Mapping
Data mapping is one of the most important parts of database applications. In a database, data doesn’t just travel one way – but two ways, from the front end to the backend (database).
In other words, whenever a user takes action in the front end – like entering information into a Customer Relations Management (CRM) tool, the data must be mapped appropriately to be entered into the backend database.
Whenever an action like submitting information takes place on the front end, the data must be updated in the back end. Regular testing is the best way to determine that this process is taking place properly, and that errors and glitches can be avoided.
2. To Verify ACID Properties
Every action taken in a database must maintain ACID properties to ensure the accuracy and consistency of data inputs. ACID means Atomicity, Consistently, Isolation and Durability.
ACID ensures that each individual action is completed properly, has no adverse effect on other tables or information, is durable enough to hold updates if the system fails, and that each action is performed in isolation. Failure in any one of these areas can lead to errors, incorrect information, and more.
3. To Verify Data Integrity Of Your Database
The overall data integrity of your database should be verified based on CRUD (Create, Retrieve, Update, and Delete) operations. All devices being used and all pages being viewed need to be tested in order to ensure that all of these operations can be performed properly, and that your accuracy is consistent and accurate throughout its entire lifecycle.
4. To Minimize Unexpected Downtime
Failing to map data properly, verify ACID properties, and test CRUD operations can result in unexpected downtime while the system is repaired or restored to a previous state. Unexpected downtime is extremely costly – and should be avoided at all costs if possible.
Testing your database regularly allows you to avoid this downtime, and identify potential errors and issues before they become severe enough to cause a system failure.
5. To Identify Bugs And Inefficiencies
Beyond simply keeping your databases in operation, testing them regularly also allows you to recognize bugs and inefficiencies that can be improved upon, and develop solutions that help the database respond to queries more quickly. You can also mitigate bugs and errors that may inefficiencies in your databases.
Always Make Sure You Test Your Databases – For All Of The Above Reasons
Whether you have your own database administrators or have hired outside DBAs, you should always make sure you test your databases for all of the above reasons – to avoid issues with stability, efficiency, and unexpected downtime!
