CompView (technology for the model
create and control)
Overview
The technological scheme creation, edition and modeling on big volume of real data in
offline and online modes. It was created on Visual C++ 4,5,6 versions.
Technology description
This is full closed and ready‐made programming technological cycle of scheme edition and
dynamical data visualization in real‐time mode. A lot of properties for each scheme object
are using.
Object Editor
The powerful build‐in editor of objects permits the almost of all modern existed editing features.
Wide area of applications:
For car building technology 
For energyeconomy analysis of energy consumption 


The technology permits:
To visualize and compute of huge volume of data (more then 100 billions of values in several formats) with high performance. The special computing methods are using to improve performance;


To zoom the data through computing zooming 
The selective visualization of data with special statistic methods 
PageView project
To do the special recompile of data; to make the reverse data depends; to do the flexible tuning to data formats. To use a lot of data formats such as ODBC, DAO, ADO, XML and more; to make multi‐channel data access.
Computational FD/H&MT:models, methods, and software
Application software is a powerful forecasting system:
 object‐oriented(to users)
 with a graphical user interface (GUI)
 with modern mathematical models
 with approved reference information databases
