Unformatted text preview: Principles of GIS GISC 4043 Lab #5 – “Oh Behave!” Generating Geodatabase Behavior with Relationships Question 1: What (if anything) happens to the Buildings? The buildings remained the same, only the parcels were deleted. Question 2: What (if anything) happens to the Buildings? Explain your observations. The buildings were deleted in addition to the parcels because I created a composite relationship between the parcels and the buildings with parcels as the origin and buildings as the destination. Since the buildings were destination objects, they couldn't exist independently of the origin objects, or parcels, when I deleted them. Therefore, the buildings were deleted because they were the related destination. This process is called a cascade delete. Question 3: What (if anything) happens to the Buildings? Explain your observations. Although only the parcels are selected, the buildings move and rotate along with the parcels in a way that they are still aligned the same way in relation to the parcels. This is another effect of creating the that they are still aligned the same way in relation to the parcels....
