it is storage place in when tha ttesting time

During recording Quick Test learns the objects and its 
properties.These properties are stored in a repository or 
some database,this is actually called as an Object 
Repository........... Thankx

Object repositry in QTP is a Storage place where it stores 
the properties of all the objects. when we execute the 
script QTP checks that the object in the app matches with 
the object in the repositry or not.

Object Repository is a file where it can store the
information of the object properties.so that while we
playback in record and playback mode ,QTP learns the
properties of that particular object and can easily findout
that object.

obj is storage place when while running qtp compare aut and obj.

Object Repository is a place where QTP keeps the 
information of the objects. While recording it identifies 
each object uniquely by a set of properties & stores it.  
While running the script, it refers the object repository & 
tries to identify the object based on the properties. 
Object repository is like a brain to the QTP. We can make 
QTP identify or ignore objects.

Object repository option from tools menu of QTP Is user to 
stored object description.

QTP CANNOT COMMUNICATE DIRECTLY TO THE APPLICATION UNDER 
TEST(AUT). THE OBJECT REPOSITRY ACTS AS TRANSLATION  B/W 
QTP AND AUT.WHEN QTP IS EXPECTED TO PERFORM SOME OPERATION 
ON APPLICATION OBJECT THEN THE  OBJECT TITLES PRESENT IN VB 
SCRIPT LINE MAY NOT BE SUFFICENT FOR THE QTP TO LOCATE THAT 
SPECIFIC APPLICATION OBJECT  AND HENCE FOR EVERY UNIQUE 
OBJECT IN THE APPLICATION TO BE IDENTIFIED BY THE QTP SUM 
OF THE MANDATRY PROPERTIES ARE TO BE ADD TO THE OBJECT 
RPOSITRY(OR).SO QTP IS EASY TO IDENTIFY THAT OBJECT.

object repository is nothinh but stores all the properties 
of an object while its recording time of an application. by 
using this we can see the properties of any object. and 
also we can export and import any objects
