第四代设计（4GD）管理系统的优势

4GD has several advantages over previous generations of data management systems:
• Flexible organization of design data
The collaborative design content can change dynamically as the design evolves.
Designers are not limited to viewing the product in predefined subassemblies.
• Independent lifecycles
Each design element has its own lifecycle. You are not limited by the lifecycle
of traditional assemblies. Each design element has its revision and status.

• Multiple hierarchical views

• Very large data sets
Because there is no concept of a structure, very large data sets can be managed
efficiently . Teamcenter loads collaborative designs much more quickly than
traditional assemblies.

element, there is no parent assembly to check out and lock.
• Efficient working sets
Designers can work with adjacent design elements, without having to check out
the next highest parent assembly that contains all the design elements.
• Concurrent work capabilities
