This article mainly explains "what are the testing methods of the database". The content of the explanation in the article is simple and clear, and it is easy to learn and understand. let's follow the editor's train of thought to study and learn "what are the testing methods of the database?"

At present, there are many active database tools in the market, such as MS-Access2010,MS SQL Server2008 R2 Oracle 10g Oracle Financial,MySQL,PostgreSQL,DB2 and so on. They have their own advantages in cost, reliability, function and security.

The following is a brief introduction to the operations represented by 'CRUD'' in the database.

C: create-- create a user.

R: retrieve-- perform the retrieval view operation.

U: update-- update database information.

D: delete-- perform the delete database operation.

The four operations mentioned above are used by ordinary users when they manipulate data.

Database test preparation:

ACID attribute

ACID refers to the abbreviation of the four basic elements for the correct execution of database transactions. Includes: atomicity (Atomicity), consistency (Consistency), isolation (Isolation), persistence (Durability). These four elements must be tested during database testing to make sure they are correct.

Data integrity

Consider that applications with different modules use the same data in different ways and perform all CRUD operations on the data. To ensure that the data contained in the database is as accurate and consistent as possible, this is data integrity.

Business accuracy

With the development of database, it is no longer simply used to store records. In fact, database systems have developed into powerful tools that provide enough extension support for developers. Database systems have more powerful features than ever before, such as referential integrity, relational constraints, triggers, and stored procedures.

How to test the database:

Create a query

To test the correctness and accuracy of the test database. First of all, the tester should be proficient in SQL and DML (database language) statements. Second, the tester should master the structure of the database. If these two conditions are met, you can rest assured to test. It is a good testing method for applications developed by small and medium-sized technologies. In addition, if the program is relatively complex, testers need to turn to developers for help. But I suggest you start testing from the beginning, both confident and able to improve your SQL technology.

Query data table

Testers can verify the results of the application's GUI operation by looking at the data table. However, for databases with a large amount of data, the query is quite tedious and tedious. Validating multiple tables is also quite difficult.

Query from developer

This is the easiest way to test the database, performing any CRUD operations from GUI and performing their respective SQL queries, and getting validation and its results from the developer. This approach seems to be the best way to test the database. If the developer queries out a statement error or does not meet the requirements of the user, the error statement can be modified as soon as possible.

Thank you for your reading. The above is the content of "what are the testing methods of the database?" after the study of this article, I believe you have a deeper understanding of what the testing methods of the database have. The specific use of the situation also needs to be verified by practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
