Difference between a memory variable and a database field.
Memory variable names must begin with a letter (A-Z, a-z) or an underscore (-), followed by any combination of letters, digits or underscores. The variable name can be of any length, but only the first ten characters are significant, so these must be unique while a database field is a part of a record held in a database,containing specific information.
