database testing training
Introduction to database testing training:
Database is long term data storage. Many systems that we use databases in the backend, where the user’s data and other supporting which means that even if the application is no longer being used, the data continues to stay in the database. And it can be used the next time by the users. Database testing training is a major testing which requires an expertise tester to checking the tables, and writing queries and procedures.

Overview of Database testing training:
Database testing can be performed in web application or desktop application. Desktop can be used in the application like SQL or Oracle. Database testing may be done in the projects like banking, health insurance, finance and these requires extensive database testing training.
Database testing training is heterogeneous. File system objects and memory objects are the storage places to store the data. Database storage is the method can build the structure for the data. By using this Database testing training we can avoid concurrency issues for replication.
In this maintainability and reporting is also an advantage of database storage to use. The testing database is used to ensure the analytics done by the application or other tools are using the correct information stored in database. To ensure the value shown on the application UI or in reports is the real data that are stored in the database tables.
Database testing training is the collection of files those are interconnected. At different types of servers, databases are not same of type. Hence the database is heterogeneous. Actual type of database process is a layered process.
In this database testing training there are four layers. Those are:
- The user interface layer
- The business layer
- The data access layer
- The database itself
In the database testing system these different layers are very important. Web software accesses the heterogeneous databases.
Basic steps in the Database testing training:
Database testing training basically follows the following steps. Those are:
- Data validity testing: Data validity testing uses SQL queries.
- Data integrity testing: Data integrity testing uses referential integrity and different constraint.
- Performance related to database: It uses table structure and design.
- Testing to procedure, triggers and functions: It should be clearly understand to further procedure.
One query about this training is that what to Test in database? In the Database testing training need to check all the functionalities which is happening on every action performed in the application. In these actions the functionalities are deletion, addition, and save options.
In the deletion we can check whether the records are removed are not from the database. With the addition we can add the records to database. We can save the data that whatever may be the data is added or deleted. These are the major roles which are monitored in the database.
Database testing uses manual testing. Manual testing training is a process of manually testing software for defects. Manual testing doesn’t use tools or automation scripting. With this manual testing higher level of automation is achieved.
Types of database testing training:
There are 3 types of database testing training. Those are Structural testing, functional testing, and Non-functional testing. At present days Database testing training is getting more complex due to business logic. It plays an important role for the applications.
Structural testing training:
In the structural testing training, all the elements inside the data repository that are used primarily for storage of data and the structural data testing is involved to validate. The validation of the databases servers is also a very important consideration in these types of testing.
Functional testing training:
Most of the transactions and operations are performed by the end users. It is a specified requirement to testing the functional database. Here some are the basic conditions to observe for database validations.
- Check the field is mandatory that allowing NULL values on that field.
- Check whether the length is sufficient size for each field.
- Check the tables whether having same names.
- Check the database if the computed fields present or not.
In this process the tester will perform the operations at database level. And it can be navigate to the relevant user interface. It is used to observe and validate the proper field validations are carried out or not.
Non-functional testing training:
Non-functional testing of database is divided into different categories as required by the business requirements. The categories may be load testing, stress testing, security testing, usability testing and compatibility testing, etc.
Need of Database testing training:
Database testing training is used in the multiple purposes. Database testing training is used to perform data integrity, validation and data consistency. Database testing is used SQL queries. Backend system is responsible to store the data and is accessed for multiple purposes. There are many reasons to use Database testing training.
- By increasing the view and stored procedures by developers the complexity of the call to Database backend is easy.
- The procedures of stored and view are somewhat difficult that contains difficult tasks. These critical tasks may be customer details or sales data, etc. These tasks are needed to test at several levels.
- In the database the data is arrived from the multiple applications. And there is a chance to register harmful or incorrect data in the database. So, there is a need to check the database regularly. Along with this there is a need to check integrity and consistency of the database.
- In the front end Block box testing is most important. But this frond end process is critical to isolate the problem.
- In the backend system process the testing is increases the robustness of the data. Hence the database testing is occurred in the backend process.
One of the main tasks when doing database migration is to perform login name migration.
The user name can basically be migrated in the database backup and restore, and the mapping relationship and permissions are unchanged before and after the migration.
The login name can be migrated in the master database backup and restore, but since the master is used as the system library, many system information of the original server is stored. After the master library is restored, the original server information will be migrated synchronously, resulting from the existing server information. Conflicts require a lot of extra work to eliminate the impact.
At this time, if you can use the script to migrate the login name, it will greatly facilitate our work.
However, the stored procedure can only move around the login name and password, and the server role cannot be migrated. Therefore, after migrate the login name, the server role, user and permissions are also migrated together. Many examples on the Internet are not explained in a unified manner.
Use the script to view the server role for the login name and move around the server roles together after migrating the login time.
Recently, after the team was doing the release before the release, the feature branches were merged back to the master and found that the DB unit test showed more than 20 failed test cases. The database developed uses SQL Server. There are more than 400 tables and more than 2000 stored procedures.
Each stored procedure is equivalent to a function in the application code. Every complex function in the code can guarantee the quality of the code to some extent by writing unit tests, as well as the stored procedure. The difficulty of UT in the code lies in decoupling, which separates the code that is involved in each other, and each breaks.
For example, the A function needs the data provided by the B function. When testing the A function, we only want to test the A function, and do not want to call B, this time we need to provide the data generated by the B function. This is called a mock.
When doing DB unit testing, the data used by the stored procedure is special, and it is persisted in the database table. More than 2,000 stored procedures are added, deleted, and changed to more than 400 tables. We need to put the data of these tables for each. T
he stored procedure is isolated. If the data used by the test cases are related to each other, in general, the order of running the unit test cases is random. If the data used in the unit test is related, it is very likely the results of the two runs are also random (but there is a way to fix the case execution order), and there are more than 20 failed cases for this reason, on two machines. The results of running out are different, some are successful, and some are failures.
Conclusion of Database testing training:
Database testing training is used to checking the tables and testing the SQL queries and procedures. Database testing can be performed in web application or desktop application. Desktop can be used in the application like SQL or Oracle. Global online trainings will give you the best corporate training on Database testing.
