A computer system relerred to as a Database Management System with Nested Time Axes (DBMS with NTA), which cooperates with a Computed Medical File and Chart System (CMFCS), employs data processing techniques to solve problems related to data collection and analysis in daily medical practice. It reconstructs irregularly or regularly collected data and places it into a database table with a standardized time axis acceptable for the CMFCS. Multiple records of an original database at irregular intervals are correlated to a progeny database with a standardized time axis by averaging, maximizing and minimizing. The DBMS with NTA consists of several database tables, each of which has a relational time axis, and corresponding programs to reconstruct a root database table to a progeny database table in hierarchical order. The DBMS with NTA cooperating with the CMFCS allows users to automatically create computer displayed medical charts from the short range view (microscopic view) via the standard view to the long range view (wide angle view) serially using several different time axes. It also creates a computer displayed medical chart showing the maximum and minimum values along with the average value in the same time axis.
