Microsoft SQL Server also allows you to specify and use user-defined composite types (UDTs). This also makes server statistics available as virtual tables and views (called dynamic management methods or DMV). In addition to tables, the database can also contain other objects, including views, stored procedures, indices, and limits, as well as transaction logs.
The SQL Server database can contain a maximum of 231 objects, and can reach multiple files at the operating system level with a maximum file size of 260 bytes (1 XB). Data in the database is stored in basic data files with the .mdf extension. Secondary data files, which are specified in the .ndf extension, are used to allow the distribution of single database data in more than one file, and optionally in more than one file system.
The log file is determined by the .ldf extension. The storage space allocated to the database is divided into pages that are numbered sequentially, every 8 KB. This page is the main I / O unit for SQL Server operations. This page is highlighted by a 96-byte header that stores page metadata, including page number, page type, blank space on the page, and the object ID it has.

Know page data on page types: data stored in databases and indexes and customization maps that contain information about how to adjust pages for tables and indices and change maps that contain information about changes made to other pages since the last copy operation returned to the top or registration or contain large data types such as images or text. While the page is the basic input / output unit, space is effectively managed in terms of a range of 8 pages.
Database elements can be expanded to 8 pages in a range (“uniform border”) or divided by up to 7 other objects (“mixed ranges”). Rows in the database table cannot reach more than one page, so the size is limited to 8 KB. However, if the data exceeds 8 KB and the row contains varchar or varbinary data, the data in this column moves to a new page (or maybe a series of pages, called allocation units) and replaces the pointer to data.
Microsoft SQL Server Management
SQL Server Management Studio (SSMS) is the first software application released with Microsoft SQL Server 2005 that is used to configure and manage all components in SQL Server Management Studio. This tool includes a text editor and graphical tool that works with server objects and properties. The main feature of SSMS is the Explorer Object, which allows users to browse, identify, and act on any object on the server.
I also sent a separate Express version that can be downloaded for free, but the latest version of SSMS is fully capable of connecting and managing each instance of SQL Server Express. Microsoft also includes compatibility with earlier versions of SQL Server, allowing newer versions of SSMS to connect to earlier versions of SQL Server. Starting with version 11, this application is based on the Visual Studio 2010 shell, using WPF for the user interface.
The version after 18 is based on Visual Studio 2017 Isolated Shell. In June 2015, Microsoft announced its intention to publish the next SSMS version independently of the SQL Server database engine version. Microsoft markets at least twelve different versions of SQL Server, aimed at viewers and workloads that differ from small to small scale applications to large applications facing the Internet with multiple concurrent users. Data storage is a database, a collection of tables with written columns.
SQL Server supports various types of data, including primitive types such as Integer, Lampung, Decimal, Char (including string characters), Varchar (variable-length character strings), binary (those data points are not set), text (text data) and so on. A boolean approach is used for integers whether symmetrical arithmetic or symmetrical circular orientation (fix) depending on the Microsoft SQL Server Management.
