The data file to store the data is based on the Page and ExtendA data page is 8 kilobytes ((8,192 b

SQL Server Architecture | Iraq Dot Net
What spins Boukhatrna when talking about the Microsoft SQL Server you are a new type of database that is not true renamed the database management system of the type of MS SQL either tower will benefit paragon from the management of databases, it gives great possibilities and advantages
As for the Relational Model shall be a tables, each table itself be independent if we want to query for specific information through the collection of tables, the result will be is the Flat Table ease with which they are either in dealing with the relational Vtkon of the ease of entry and modification
In the SQL Sever Hnal the two types of databases, the first formed by the SQL Sever and utilized to adjust the settings of the SQL same second type here talking about databases that a user of SQL Server management System
In fact, data is stored in the database Albeanatwalta must be stored somewhere in the Server and managed by the SQL Server the SQL Server uses files with the extension. MDF, which is the main file for the database and uses the SQL secondary file with the extension. NDF, which could to contend with secondarily for each database file and one of a kind. MDF and more than a file. NDF
The data file to store the data is based on the Page and ExtendA data page is 8 kilobytes ((8,192 bytes) The page will be available 8.060 Per Record is if the restriction to Aimlo the Page van the Page will mobilize enrollment second, and so on with the observation that the Row can not be extends through the pages in the event of rows that were stored in the page exceed paragon 8KB, the SQL Server moves the variable-sized columns to the New Page Dedicated original page and called the process ROW_OVERFLOW_DATA
That the SQl Server supports reading and writing to the RAM, the spectrum to increase the speed of performance that the buffer pool Linkin be stored in that one 8KB and is the Aamlah index of the results Buffer pool when we want to read from the ram be faster than what we بالولوج to into the SQL and then reading
Suppose that more than 1200 Record doing identical to this query scattered through the 750 page, the the SQL serve will search for the page desired and then prohibits the required data to the user by putting them in the RAM either beige which they are called to the RAM it are not taken to delete only After we bring Bejat the other the buffer pool, the spectrum for the possibility of accelerating the process if the same was called the Query
Maybe now curiosity you have to know how this is the amendment to the database files essential to the work amendment Alyalmelvat basic ((database files core)) of SQL Server is actively called the checkpoint and no page is subject to change paragon diagnose or determine علىانها dirty page when he spoke of the process of the CheckPoint on The page in the buffer is the SQL processing the Dirty page and then returned to the original page any process is overwrite
