Regarding Windchill data storage and data models for CREO

Hi there,

I just need some info regarding the data storage and data models in Windchill.

since lone time, we have been using Windchill and CREO to save CREO part, assy and drawings.

now I need to migrate some of CREO models from another system to Windchill.

but I don't how to do that.

Is there any way to see the data models for CREO data?

For e.g.:

If I create 3d model and save it in Windchill, how it's being saved inside oracle database.

Assy-1

|------Part1

|------Part2

    |--------drawing2

|------Drawing-1

where metadat is stored?

What're the different connections? how they're stored in database

how physical files being stored?

I really appreciate if you would suggest something.

Also, let me know if there is any tool that I can use to see the data models in Windchill.

Thanks In adv.
