What is SQL Server?
SQL Server is Microsoft’s relational database platform for storing, managing, securing, and querying data with SQL.
Is SQL Server suitable for beginners?
Yes. Beginners can start with databases, tables, SELECT queries, filters, and basic data modifications before moving to advanced topics.
What are tables, data types, and constraints in SQL Server?
Tables organize data into rows and columns, data types define the kind of value a column stores, and constraints enforce rules such as unique or required values.
How do SQL Server joins work?
Joins combine rows from related tables. INNER JOIN returns matches, LEFT and RIGHT JOIN retain unmatched rows from one side, FULL JOIN retains all rows, and SELF JOIN compares a table to itself.
Why are indexes important in SQL Server?
Indexes help SQL Server locate data faster, improving many query operations. However, too many indexes can slow INSERT, UPDATE, and DELETE operations.
What is the difference between SQL and SQL Server?
SQL is the language used to query and manage relational data. SQL Server is Microsoft’s database management system that uses SQL, including the T-SQL dialect.
Can SQL Server be used for business intelligence reporting?
Yes. SQL Server can prepare, aggregate, and query business data for reports, dashboards, analytics, and BI tools.
