Database testing is one of the major testing which requires tester to expertise in
checking tables, writing queries and procedures. Testing can be performed in web
application or desktop and database can be used in the application like SQL or Oracle.
CariKture India Database testing usually consists of a layered process, including the user interface (UI) layer, the business layer, the data access layer and the database itself. The UI layer deals with the interface design of the database, while the business layer includes databases supporting business strategies. Databases, the collection of interconnected files on a server, storing information, may not deal with the same type of data, i.e. databases may be heterogeneous. As a result, many kinds of implementation and integration errors may occur in large database systems, which negatively affect the system's performance, reliability, consistency and security. Thus, it is important to test in order to obtain a database system which satisfies the ACID properties (Atomicity, Consistency, Isolation, and Durability) of a database management system.
CariKture India Database test offerings include:
Data Mapping: In software systems, data often travels back and forth from the UI (user interface) to the backend DB and vice versa. So these are some aspects to watch for:
properties validation: Atomicity, Consistency, Isolation, and Durability. Every transaction a DB performs has to adhere to these four properties.
Data integrity: This means that following any of the CRUD operations,
the updated and most recent values/status of shared data should appear on all the forms
and screens. A value should not be updated on one screen and display an older value on
another one. So devise your DB test cases in a way to include checking the data in all
the places it appears to see if it is consistently the same.
Business rule conformity: More complexity in databases means more complicated components like relational constraints, triggers, stored procedures, etc. So testers will have to come up with appropriate SQL queries in order to validate these complex objects.
