Experiences in Designing a Data Retrieval Capability for a Large Data Base,

摘要

DATAR is a package of subroutines that provide data retrieval capabilities for a large weather data base. The design of this package was a valuable learning experience for the author. Questions of portability had to be resolved since the package must run on several different computers. Questions of interface arose since DATAR would be imbedded in other programs. Also,it was desirable to have changes to the subroutines be transparent to the user. And the list goes on. It is the author's intent to discuss the design of DATAR and to share the learning experiences. (Author)
