Explore ins and outs of Database Testing in details

Database testing involves a thorough knowledge of a specific application and requires more defined plan of approach to test data. At a minimum, the examiner should be able to view the database consists of the points specified in the workflow. It 'important for the tester to be aware of database concepts, design and implementation of standards.

Key questions for the test database include:
a. Data integrity;
b. Validity of the data (stored in the database correctly);
c. Data manipulation and updates (update on the number of books sold, books, etc. are available).

2 The following list can do a lot more test cases for administrative purposes:
1. The design of databases.
2. Identify the main risks.
3. Understand the security controls designed to understand the user IDs in read / write commands to the database.
4. Understand how to update databases and maintenance updates.
5. Ensure performance requirements are met.
6. Ensure proper operation, the capacity and performance when multiple users run the same task or query the same time (and include the simultaneous use of up to or concurrent with the specifications).
7. Ensure that the work of backup and recovery as expected and does not affect the availability requirements.
8. Make sure that the database allows the maximum number of connections that the system is designed for management.
9. Ensure that the database operations have enough space and memory for the amount of data. Include expanding the system when the physical limits of space and memory are exceeded. [Via: Introduction to Software Testing Tamra]

3 To test a database must have a database for testing. In one project, each developer must have its own local database, the developer uses to test against. This approach has several advantages. First, test database is slow by nature, even when running tests with a local copy of the database, do not add network latency into the equation for the test against a remote database data, which would slow down again. Secondly, and most importantly, it is safer because it is isolated from the operation of the database. This means that you can do what is needed for the database without affecting production data or other developers.
As a further step, you may also have a local database to the second spot, particularly for automated testing. This allows a database of the local population to perform manual testing, without having to worry that influence automated test. [Via: Hibernate quickly Heudecker Nick Patrick Pic]

4 Testers use the basics of database design and apply them to find common errors in database systems. She database to identify design flaws and poor design policy. Testers design test cases to find the common problem of the database and apply the principles of standardization of the database in a test project. The tester must have knowledge of SQL and relational databases.

5 Fundamentals of relational databases for testing
Take a book or go online and polish their fundamentals of databases, such as what is a relational database, the types of data integrity, lack of integrity of the data for errors, the identification of defects in design, table control structure to reveal the design problems of screening tests: reading a disk repair relations between the tables: 1-1, 1-many, many, many, as it must be sought to test relational databases, etc.

Databases are an integral part of today's software applications. It does not matter at all if we are talking about web or desktop, client-server or peer group, business or individual entrepreneurs, the main database for this work. Similarly, if health will be covered by the lease sale, or delivery of the application and control of the ship, behind the scenes the database is always in action.

Moreover, the complexity of applications, such as increasing demand in the database emerge stronger and more confident. In addition, for applications with high frequency of transactions (such as banks or financial applications), it is necessary that all the functions of the instrument at the anchor database.

Currently, the database means that there are different markets, such as MS-%u200B%u200BAccess2010, MS SQL Server 2008 R2, Oracle 10g, Oracle Financial, MySQL, PostgreSQL, DB2, etc. These costs vary, reliability and safety performance. Each comic books have their advantages and disadvantages. One thing for sure, business applications to be built using the same database.
