This is a simulated temporal data set, which models the 
evolution of employees (change of title, salary, and deptno),
 and departments (change of mgrno) in a company, from
1985-01-01 to now. The history is temporally grouped, and
represented as XML format. The employees' history is 
cut into small XML documents, of similar sizes. The departments'
history is stored in departments.xml.  The schemas of the 
documents are in employees.xsd, and departments.xsd respectively.

Files in the archive include:
departments.xml

employees.xsd
departments.xsd

employees.tar.gz
(uncompressed as three folders of XML documents of employees, 
of size 335MB, with 500,000 employees)
