Definition

Most of the time, views can be defined as “virtual or logical” tables, but if we expand this basic definition we can understand the views more clearly. A view is a query that is stored in the database and returns the result set of the query in which it is defined. The query that defines the view can be composed of one or more tables.

Object Explorer

Object Explorer contains different components of one or more instances of SQL Server in a hierarchical manner. You can view and manage components such as Databases, Security, Server Objects, Replication, Polybase, Management, etc. Expand the component node to see further objects.

Security

Managing security for your database server is extremely important. The Security node is below the Databases node in the Object Explorer. You can create Logins and assign Server roles for any database instance. In addition, you can assign role-based security to logins and users. The Server roles you create here have server-wide scope.

Server Objects

The Server Objects node in SSMS has four sub-nodes: Backup devices, EndPoints, Linked Servers, and Triggers. A linked server is a method by which a SQL Server can talk to another ODBC database with a T-SQL statement. SQL Server EndPoints are a point of entry into SQL Server.

Replication

Replication is a set of technologies for copying and distributing data and database objects between databases and synchronizing databases. This is mainly used for maintaining consistency between databases.

Polybase

Polybase allows your SQL Server to query directly from other SQL Server, Oracle, MongoDB, Hadoop clusters, Teradata, Cosmos DB by installing client connection software using T-SQL separately. Polybase is used for data virtualization.

Query and Text Editor

Open a query editor by clicking on the New Query on the tool bar. Query editor lets you create, edit & execute Transact SQL (T-SQL) statements. It is equipped with IntelliSense support by auto-completing the script by suggesting variants. This makes writing & debugging code easier and faster.
