          A database is an organized collection of structured information, or data, typically stored electronically
          in a computer system. Data within most common types of databases is typically organised in rows and
          columns. The data can then be easily accessed, managed, modified, updated, controlled, and organised.


          WORKING WITH DATABASES IN EXCEL
          Excel is not a database management system but still provides several features that let you work with
          data and manipulate it in different ways. Excel databases provide a simple way to analyse data (such as
          sales numbers and forecasts), look at various calculations, and compare different data sets.

          Creating a Database Table
          A Table in Excel is a simple way to organise
          data in the form of a database. Tables enable
          sorting,  filtering,  and  presenting  data  in  a
          lucid  manner.  Creating  a  database  table  is
          similar to creating any spreadsheet in Excel.
          The  important  point  to  remember  is  that
          each column of values in the data must have
          a heading.

          To create a database table in Excel:        1
            1.  Create  a  worksheet  as  shown  in  the
                image.

            2.  On the Insert tab, click the Table button in the Tables group.

                 The Create Table dialog box appears.

                                               3.  Specify the cell range that holds the data in the required data.
            4                                      Mark the My table has headers check box.
