Microsoft SQL:04 - SQL Server and Indexes

Each modern business needs to have a way of collecting and analyzing large amounts of data.
There are many Relational Database Management Systems (RDBMS) you could choose from, but Microsoft’s SQL Server is the most popular one used by top enterprises as well as small to medium-sized businesses.
Microsoft SQL Server is a relational database management system developed by Microsoft.
As a database, it is a software product whose primary function is to store and retrieve data as requested by other software applications, be it those on the same computer or those running on another computer across a network (including the Internet).
There are at least a dozen different editions of Microsoft SQL Server aimed at different audiences and for workloads ranging from small single-machine applications to large Internet-facing applications with many concurrent users.
Its primary query languages are T-SQL and ANSI SQL.
