SQL Query Analyzer is a helpful tool when using Microsoft SQL Server. [citation needed] One commonly used function, [vague] create_input_dialog["label"], is used to validate the output with user inputs. The design of forms for automated database testing, form front-end and back-end, is helpful to database maintenance workers. Data load testing:
Microsoft SQL Server (Structured Query Language) is a proprietary relational database management system developed by Microsoft.As a database server, it is a software product with the primary function of storing and retrieving data as requested by other software applications—which may run either on the same computer or on another computer across a network (including the Internet).

Pros and cons efficient for exact matches on key field; not suitable for range retrieval, which requires sequential storage; calculates where the record is stored based on fields in the record; hash functions ensure even spread of data; collisions are possible, so collision detection and restoration is required

A relational database (RDB [1]) is a database based on the relational model of data, as proposed by E. F. Codd in 1970. [2]A Relational Database Management System (RDBMS) is a type of database management system that stores data in a structured format using rows and columns.

However, SQL databases deviate from the relational model in many details, and Codd fiercely argued against deviations that compromise the original principles. [3]
