-  Most vaults are local. 
		   
		
  
		-  Foreign vaults are used with Adaplets, which allow data from
		  virtually any source to be modeled as objects. 
		   
		
  
		-  External vaults are used with External stores that contain data
		  maintained by external
		  servers. 
		
  
	 
   
	  
	  When defining a vault in MQL, you do not need to specify which type it
		is. The system knows which type of vault you are defining by the parameters you
		specify for the vault. 
	 
 
	  
		-  For local vaults, you define Oracle tablespaces using the Tablespace
		  and Indexspace clauses. 
		   
		
  
		-  For foreign vaults, you specify tablespaces, and Interface and Map
		  fields (using the Interface and Map clauses). 
		
  
		-  External vaults need only a parameters file.
