In this section the $asic steps 7or creating a #asterDetail 7or! are introduced.

relationship.


46/139

)( T$e ,aster:Detail Relations$ip

The #aster6Detail relationship is a co!!on relationship $etween entities in a

$usiness. In an -ntit,60elationship diagra! these are shown as HOne to #an,H

relationships. In a ph,sical data$ase design a singleMasterrecord re7erences

one or !ore detailrecords in another ta$le. = record in the detail ta$le willrelate to eactl, one !aster record in the !aster ta$le. =nother na!e 7or this

relationship is called parent6child. -a!ples o7 this relationship include

= 'usto!er Order with !an, OrderIte!s.

= Depart!ent with !an, -!plo,ees.

=n -!plo,ee with !an, Dependents.

= 'o!pan, with !an, "ranch O77ices.

= 0ecipe with !an, 0ecipeSteps.

=n Inventor, location with !an, Inventor, Ite!s.

Oracle or!s i!ple!ents the !aster6detail relationship using two data $loc*s.

The 7irst $loc* corresponds to the !aster ta$le and the second $loc*

corresponds to the detail ta$le. There are two !a%or 7unctions in a #aster6

Detail 7or!

Oracle or!s coordinates values $etween the two $loc*s through a

series o7 7or! and $loc* level triggers.

Oracle or!s guarantees that the detail $loc* will displa, onl, records

that are associated with the current record in the !aster $loc*.

&ote that a #aster6Detail 7or! is si!pl, one wa, o7 viewing the data in tworelated ta$les. or!s do not a77ect the sche!a in ter!s o7 creating dropping or

en7orcing data$ase level re7erential integrit, constraints.

) Steps to Create a ,aster:Detail Form

In this section a set o7 step $, step instructions 7or creating a #aster6detail

7or! are given. The 7or! will allow a user to quer, a given depart!ent in the

co!pan, and then will displa, all o7 the e!plo,ees in that co!pan,.

The sche!a used is the sa!e one suggested in the Prerequisitessection at the$eginning o7 this tutorial. &otice that the D&O colu!n in the EMPLOYEEta$le
