Index architecture in ms sql server

Clustered Index Architecture. In SQL Server, indexes are organized as B-Trees. Each page in an index B-tree is called an index node. The top node of the B-tree is called the root node. The bottom nodes in the index are called the leaf nodes. Any index levels between the root and the leaf nodes are collectively known as intermediate levels. A special type of token-based functional index that is built and maintained by the Microsoft Full-Text Engine for SQL Server. It provides efficient support for sophisticated word searches in character string data. Starting with SQL Server 2016 (13.x), the object can be a table stored with a clustered columnstore index. Azure SQL Database supports the three-part name format database_name.[schema_name].object_name when the database_name is the current database or the database_name is tempdb and the object_name starts with #.

If you create an index on an existing table that has enough rows to generate eight pages in the index, all allocations to the index are in uniform extents. However, starting with SQL Server 2016 (13.x), the default for all allocations in the database is uniform extents. In SQL Server, rowstore refers to a table where the underlying data storage format is a heap, a clustered index, or a memory-optimized table. Note In discussions about columnstore indexes, the terms rowstore and columnstore are used to emphasize the format for the data storage. SQL Server provides us with two main types of indexes, the Clustered index that stores the actual data rows of the table at the leaf level of the index, in addition to controlling the sorting criteria of the data within the data pages and the order of the pages itself, based on the clustered index key. This is the reason behind the ability to In this section, we will rebuild index via SQL Server Management Studio and Transact-SQL. Reorganizing and Rebuilding Index via MS SQL Server Management Studio. To rebuild any fragmented index of SQL Server, there may be two possible conditions i.e. rebuilding a single index another rebuilding all indexes of a table. MS SQL Server is a relational database management system (RDBMS) developed by Microsoft. This product is built for the basic function of storing retrieving data as required by other applications. It can be run either on the same computer or on another across a network. This tutorial explains some MS SQL Server is a client-server architecture. MS SQL Server process starts with the client application sending a request. The SQL Server accepts, processes and replies to the request with processed data. Let's discuss in detail the entire architecture shown below:

This is a tree data structure that allows SQL Server to keep data  Jan 20, 2012 The non-leaf levels are a structure built on top of the leaf level, which enable SQL Server to: Maintain the index's entries in index key sequence.
