Databases are the culmination of multiple files which are stacked together and further meticulously interconnected. Database is one of the inevitable parts of a software testing application these days. It hardly matters, if the application is run on a web or a desktop, client server or peer to peer, enterprise or individual business, this is working at backend which becomes a very important metric to be considered.
As a matter of fact, the databases of various servers may be or may not be of the same type. This means that it might not be on heterogeneous in nature. The scalability of database and the subsequent server becomes less significance about the various domains (Healthcare, Finance, IT, etc) it implements. At the backend, the database has always been on action.
Structurally database systems comprises of four distinctive layers:
The user interface (UI) layer
The business layer
The data access layer
The database layer
Database Tools (DB Tools)
To be very precise, as and when the complexity of an application increases the need for a stronger, robust and a secure database becomes ardently imperative. The web application on the contrary, accommodates within itself the highest frequency of transactions such as the banking and the finance domains have given rise to a fully integrated database tool.
The popular database tools that are readily available in the market today are:
MS SQL Server 2008 r2,
Oracle 10 g,
These are considered to be very stable and known to be having robustness in terms of its features and security.
Anecdote 1: The complex business application in today’s trend has been built using any of these tools.
Database testing tool is being considered as one of the mandatory requirement when it comes to the backend testing. The data becomes a very crucial part in the database and efforts have to be made to give the smooth seamless functions of a business application both in terms of the Front End (UI) and the robust Back End.
Anecdote 2: This testing can be termed as a layered process and testing at these different layers are very pivotal. Since, web software accesses the database from different back ends; this testing plays an instrumental role in having a consistent system as a whole.
