I think that it is worth considering Object-Oriented database for the model intensive applications , where performance is less of an issue , though I understand that it does n't fall naturally under the J2EE umbrella . This means that to make changes , you must be on the same machine where mysqld is running , you must connect as the MySQL root user , and the root user must have the insert privilege for the mysql database and the reload administrative privilege . In some cases , where capacity was swapped on a 1:1 basis , money never switched hands , but executives still counted the contract as revenue . Innovative engineering technology went into the new courthouse in Phoenix , Arizona , where climate is a major consideration . Republicans are very good at sounding good in the abstract on security , mostly by confusing the issue of where blame is to be placed when things go wrong , but after several years of them have undivided control over security policy , its become harder for them to pass off blame for failures . I believe that this effect alone makes OOP difficult to justify in any application where performance is important .
