The structure of such views is defined by specifying the tables and fields that are required. Fields which are not required can be hidden, thereby minimizing the interfaces. A view can be used in ABA programs for data selection. Following demo shows how to create database view for two database tables having foreign !ey relationship.

%. 4o to transaction 5%% 67 select radio button 89iew8 67 enter the name of the view 67 press 8+reate8.
&. 3n 8Tables8 enter the name of the base tables which we want to include in our view. 3n this case we will
be entering tables as #$%&'BA() * #$%&'A++-(T.
<. (e=t, we need to lin! the entered tables by specifying the fields in >oin condition. "e can also derivethe >oin conditions from e=isting foreign !eys between the base tables of the view. To do this, position
the cursor on the table names and clic! on present at the bottom.?. Below pop up comes wherein lin!ed tables are present. elect the tables and press 8+opy8.
@. n clic!ing copy button, >oin condition will be derived from the base tables. 3n our case, we have the
below shown conditions.
. 3n the 89iew Flds8 tab, we need to enter all the fields, we want in our view from the database tables."e can either enter the fields directly or we can copy them from base tables. ater can be achieved
by pressing button present in the tab 89iew Flds8. "e can also include completetable in a view by entering * in 89iew field8 * table name in 8Table8. 3f fields are inserted or deleted fromthis table, similar modification will be automatically made in view structure.
C. n pressing 8Table fields8 button we get a popup li!ewise shown below. +hoose the table whose fieldswe want to include in our view. Another popup will be shown select the fields we want to include andpress 8+opy8.
