Chapter 5: Frequently Asked Questions
What Is SQL?
SQL stands for Structured Query Language. It is a programming language used to manage and manipulate relational databases.
What Is a Relational Database?
A relational database is a database that organizes data into one or more tables, with each table consisting of rows and columns. The tables are related to each other by key fields.
What Is SQL Server Management Studio?
SQL Server Management Studio is a client tool used to manage and administer SQL Server databases. It provides a range of features and functionality for managing data, including creating tables, running queries, and managing security.
What Is a Clustered Index?
A clustered index is an index that determines the physical order of the data in a table. It is created on the primary key of a table and is used to improve query performance.
What Is a Nonclustered Index?
A nonclustered index is an index that is created on a column or set of columns that are not part of the primary key. It is used to speed up queries that search for specific values.
Conclusion
In conclusion, Microsoft SQL Server is a powerful and versatile database management system that can help businesses of all sizes manage their data more effectively.
