B) Predictable use of data In prototyping, implementation and maintenance activities are repeated as necessary until the product is correct. An organization that has a strong command-and-control system usually requires a vertical, tall organizational administrative structure. Minimize name changes across environments. Encoding table names to make them shorter is another arbitrary naming standard that should be avoided.
