What are the differences between a logical view and a physical view of a database? Which would be more important for accountants who are involved in the design of a database that will store business event information? ANS. Relational database tables are logical views of data that are physically stored in the database. The logical database view is how the data appear to be stored when the user accesses the database; that is, it is the way the user sees the database. The logical view provides a structure that the user can use to extract data from the database. The physical view is a representation of the way in which the data are stored on the disk or other storage medium used by the database management system. The physical view of the data often has little relation to the logical view. Thus, accountants who use DBMSs do not need to worry about the details of the physical storage of the data. They do, however, need to understand the logical view of the data. DQ5-12
