As a software application's brain, its database is crucial to ensure that it runs smoothly. Database testing is the process of making sure the database is functioning properly. In this article, we highlight some of the things you should know before diving in. Take a look!

1. 7 Things To Know About
Database Testing
What is Database Testing?
Database testing is the process of testing a database for integrity and consistency. It is
performed to ensure that the database can be used to support a release.
The components tested during database testing include:
● Database design (including any tables, columns, indexes, and constraints)
● Algorithms used to access data in the table(s)
● Schema generation (including how data is stored on disk)
● Data storage/retrieval routines (including how data is stored in memory or on
disk)
● Security considerations

2. What are some general rules of database testing?
Start early
● Typically, database testing should be performed in the early stages of the release
management process.
● Because you will want to know whether your database has the right number of
tables, fields, and constraints in place before you start writing code for it.
● If there are problems with your database structure, then it can be very difficult to
change later on without causing disaster.
Check for correct functionality.
● During this testing phase, you'll also want to test whether your database supports
all necessary functions for your product or service.
● For example, if it stores customer information correctly or allows customers to
register for an account easily.
Check for customization compatibility.
● You'll also want to check that any customizations you make do not affect existing
functionality unexpectedly (for example, if you add a field that stores an
expiration date for customers' credit cards).
What are the various databases used in the release
management process?
Hierarchical databases
In release management, a hierarchical database is a database that stores information in
a hierarchy of folders. The folders are arranged in order from greatest important to least
important.
A hierarchical database has multiple levels of granularity. The more granular units are,
the more information they can store. This means that if you have one item with three
sub-items, each sub-item can have its level of detail.

3. The information stored in a hierarchical database can be used to determine the priority
levels of each release and plan future releases accordingly.

Network databases
A network database (NDB) is a software component that manages the relationship
between multiple disparate databases.
The NDB provides a method for managing the data that is stored in each database so
that multiple applications can access it and then be updated from one or more of those
applications.
The network database also maintains a mapping between the name of the tables in
each database and the names of their corresponding fields in every table.
This allows you to create views and other applications that can access these data
sources without having to know how they're organized within the underlying SQL
database.
Object-oriented databases
Object-oriented databases are databases that use objects as their fundamental data
structure. Objects are essentially self-contained units of information, which can contain
other objects and can be stored in relational and object-oriented databases.
What are the objectives of database testing?
The objectives of the database testing include the following:
● Ensure data mapping
● Ensure ACID (Atomicity, Consistency, Isolation, and Durability) properties of
transactions
● ensure data integrity
● Ensure the accuracy of the business rules

4. What are the components of database testing?
● Database schema
● Transactions
● Store procedure
● Field constraints
● Triggers
What's the database testing process?
● Test environment setup
● Test scenario generation
● Execution
● Analysis
● Log defects
What are the types of database testing?
Structural Database Testing
Structural database testing is a testing practice that checks the integrity of a database
by ensuring that all tables and stored procedures are the proper data types and have no
logic errors.
The components of structural database testing include:
-Data types
-Stored procedures
-Connections
Functional Database Testing
Functional database testing is a type of software testing in the release management
process that focuses on testing the functional aspects of a database.
Functional database testing includes:
-Initialization and startup test
-Preventive maintenance testing

5. -Testing for performance issues
-Testing for security issues
Non-functional Testing
Non-functional testing deals with evaluating databases based on business
requirements.
Some of the vital parts of non-functional testing include:
● Load testing
● Stress Testing
● Security Testing
● Usability Testing
● Compatibility Testing
