Identifying all the child objects of a parent object

Hi All,

I have an object(standar/custom) and need to identify all the related objects(lookup) of that object.
Let's say I have Account object and this object might be related as lookup to many other objects, how can I find all those objects ?

Thanks,
D

Use Dynami apex

For getting All Parent objects:

  
for(Schema.SobjectField strFld: Account.SobjectType.getDescribe().fields.getMap().Values()){
if(strFld.getDescribe().getType() == Schema.DisplayType.REFERENCE){
system.debug(‘==parent object=’+strFld.getDescribe().getReferenceTo());
}
}


For getting All Child objects: 
Schema.DescribeSObjectResult R = Account.SObjectType.getDescribe();
for (Schema.ChildRelationship cr: R.getChildRelationships()) {
system.debug(‘====child object===’+cr.getChildSObject());
}

A small change in @Raj's code:

Schema.DescribeSObjectResult R = Account.SObjectType.getDescribe();
for (Schema.ChildRelationship cr: R.getChildRelationships()) {
    if (cr.isRestrictedDelete()) {
        system.debug(‘====child object===’+cr.getChildSObject());
     }
}

Schema.getGlobalDescribe().get(fObjectName).getDescribe();
(here fObjectName is the name of the object in string)
