fragmentation

  • why fragementation occurs ,how to resolve the fragmentation ?

  • As the database grows data stops being grouped on the same pages/extents meaning that as you query tables SQL is having to search through a larger amount of pages etc to find the data that you need.

    By reindexing tables SQL rearranges the data into more logical page/extants grouping table data together improving speed when querying the data. By setting a sensible fillfactor you can leave space on pages to ensure that as tables grow the data doesn`t fragment quickly.
