What is PDM:
Product Data Management manages design, R D, manufacturing, and other data. The Design and R D data must be synchronized with the manufacturing data, which must be paperless.
Data managed by PDM includes:
Design Information of CAD, cam, and CAE-bom, configuration file, and design File
MRP and CAD Synchronization
Process Information: workflow, approval relationship, etc.
What do PDM software have? Storm history:

As the material of the lithium battery itself determines that it can not be overcharge, over-discharge, over-current, short-circuit and ultra-high temperature charge and discharge, lithium battery components will always follow a delicate protection plate and a piece of current safety device appears

Horizon is a subproject of OpenStack that provides a Web front-end console (called a dashboard) to demonstrate the functionality of OpenStack. Usually, we start from horizon, Dashboard to understand the OpenStack. In fact, Horizon does not add any new functionality to OpenStack, it only uses the OpenStack part of the API, so we can extend the horizon function and extend the
