The bar graphs in the Size Overview section plot the comparative sizes of the 5 largest tables and indexes that reside within the selected database:

  • The Top 5 Largest Tables bar graph represents the comparative sizes of the 5 largest tables that reside in the database; a vertical key displays the table size in megabytes.
  • The Top 5 Largest Indexes bar graph represents the comparative sizes of the 5 largest indexes that reside in the database; a vertical key displays the index size in megabytes.

The Objects Activity table provides a detailed analysis of the activity for each table that resides within the database. Click a column heading to sort the table by the values within the column; click again to reverse the sort order.

  • The Schema column identifies the schema in which the specified table resides.
