title: What are locking issues in OLAP?
body: <p>In one local financial institution I was rebuked by their programmers for expressing them my opinion that (their programmers' obsession with) (b)locking issues in their MS SQL Server 2005 OLAP (SSAS) database(s) did not make much sense to me. (The OLTP databases are SQL Server, Oracle and non-RDBMS ERP).   </p>
  
  <p>What are locking issues in OLAP processing if OLAP (SSAS) databases are used <strong>only for reading</strong> (read-only after deployment)?  </p>
  
  <p>In which context do such (an whic?)  issues arise - during SSIS processing and transfer of data from OLTP databases?<br>
  during deployment of SSAS (OLAP) databases to SSAS? </p>
  
  <p>This question is not restricted to SQL Server.  </p>
