Fig. 1. Integral structure of Tracing system
This tracing system installed respectively in the production process, wholesale,
retail link links, and in every link , it all involved operation in the database, in the
inquiry platform, it is a system that different from the bottom, only provides function
of inquiry prediction , also want to do the database operation. In the production
process and wholesale and retail link are linked with card to connect, which store in
the link with the basic information of the cargo, enabling us to in the inquiry platform
be traced back to the cargo from the production to sales of the entire process, at the
bottom and top database, it involves operations on data, and in two systems, the
existing data transfer function, therefore, it improves the function of data processing
the request.
For instance in the underlying database contains the database tables as follows:
daily purchasing information table, sales information table, etc., and the top of the
table, contains tables as follows: purchasing information table, sales information
table, etc. Although the tables in the top and bottom name of some form and structure
are the same, yet its storage of data is not the same.At the bottom of deposit is daily
sales records, and on the top floor contains a related information collection, it makes
search analysis be more efficient and accurate, when we use the inquiry platform to
inquiry ,we need to integrate data of several months or even years, for management,
but in the meanwhile, database query data in constantly update, this makes
programmers in processing, must spend a lot more in technic, such ability make data
inquiried out more accurate, the results predicted is more credible.
As is known to all, now Microsoft for the vast number of users and programmers
provides powerful data access architecture, as below:
