Why
19/05/2017 EA and version control in practice 4
• Historical information of model
• Historical information of part(s) of the model
• Alignment with other deliverables
• Multiple users (disciplines)
• Re-use knowledge
• Personal sandbox

Need to know
• Enterprise Architect Project file (EAP) always needed
• EAP contains relational model
• Only “simple” merge / compare
• Only Packages can be saved as XMI file
• “meta data” stored in EAP

Configuration of DiVetro
• Consultants work at different locations
• Consultants don’t always have connection to DiVetro network
• Re-usable knowledge across models / customers
• Quick access to work of colleague (peer review)
• Multiple users work on the same model

Best practices DiVetro
1. Don’t use the default naming settings
2. Don’t put the EAP under version control
3. Choose logical names for version control ID
4. Don’t use standard VC commands (outside EA)
5. Don’t use “Check out branch” option
6. Make the model fit for purpose
7. Look before you leap
