HSPD Assembly: The dBASE application examined in this portion of the research was assembled by David Battle of the National Park Service. As mentioned previously, the parameters for the HSPD required that as a database system, it be based on the current NPS DBMS standard, "dBASE III PLUS." Since the actual design and assembly of the HSPD preceded this research effort, the description of the assembly process will not be discussed in this document. Numerous books and articles have been published on dBASE (and dBASE compatible) DBMS applications which cover the developmental processes in detail, and interested readers should refer to those for elaboration on the assembly of DBMS systems of this type.
