Because the process of identifying attributes yields information from many different sources, the information can contain considerable redundancy. Users and data processing professionals have very different ways of perceiving the same data. The same piece of information might be called by several names, making it difficult to see that these names are synonyms for the same attribute. In addition, two different pieces of data might sometimes be called by the same name.
As soon as the business meaning of each attribute is clear, you should establish conventions for naming the attributes. Adopting a set of standardized naming conventions appropriate for the organization saves much time and confusion, and helps to ensure an efficient and effective design.
