Giving a table or column a temporary name or alias in a SQL query is known as aliasing. In the context of a given query, it makes it possible to refer to a different table or column, hence  enables to simplify complex queries, enhance readability, and resolve naming conflicts in a query. Table Aliasing: When utilizing table aliases, give a table in the query a temporary name. This is especially helpful when refers to a table with a long or complicated name or if need to link several tables. Table aliasing's fundamental syntax is as follows: SELECT alias.column_name FROM table_name AS alias; Consider the following scenario: Extract the names of the employees along with the names

The architecture of SQL Server is based on the client-server model, where clients send requests to the server for accessing or modifying data stored in the database. The SQL Server architecture consists of three main components: the client, the SQL Server instance, and the operating system. Here is a brief explanation of each main component: Client: This component is responsible for sending requests to the SQL Server instance and receiving the results. The client can be any application or tool that can connect to SQL Server, such as SQL Server Management Studio, Visual Studio, .NET applications, web applications, desktop applications, and mobile apps. Client communicates with the SQL Server instance using a network protocol such as TCP/IP. SQL Server Instance: This component is the core of the SQL Server architecture. It includes the SQL Engine, which is responsible for processing SQL queries, and the storage engine, which is responsible for managi

The relational database management system (RDBMS) known as SQL Server was developed by Microsoft. Data in relational database format is stored, managed, and retrieved using the SQL language (Structured Query Language). SQL Server supports the relational database management language SQL.  A type of database management system (DBMS) used to manage and organise data is called a relational database management system, or RDBMS for short. The relational database paradigm was first proposed by E.F. Codd in 1970. It is predicated on the notion of a table or relation that contains data in rows and columns. Every table in an RDBMS contains a connected set of data that is organised into relations or tables. Each row in a table represents a distinct record, and each column represents a distinct piece of data or attribute. The relationships between tables are defined through the usage of keys, such as primary keys and foreign keys, which are used to connect records in different tables. Compared to
