Studies have shown that companies with high levels of standardization reduce the cost of supporting end users by as much as 35 percent or more as compared to companies with low levels of standardization. For example, standards can be developed that outline how requests are made to create a new database or make changes to existing databases, and that specify which types of database objects and DBMS features are favored and under which circumstances they are to be avoided. Specific guidelines are needed to accomplish migration in a manner conducive to the usage of each environment.
