Industrial Data Processing
Understanding Industrial Data Processing Fundamentals
Industrial data processing addresses the unique challenges of handling massive volumes of heterogeneous data generated by industrial systems. Unlike traditional business data processing, industrial data processing must handle continuous time series data streams, maintain real-time processing capabilities, and ensure data integrity across diverse operational systems operating in harsh industrial environments.
The discipline encompasses everything from edge data processing at sensor level to cloud-based analytics platforms, creating a comprehensive data processing ecosystem that supports both immediate operational needs and long-term strategic analysis.

What’s a Rich Text element?
The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.
Static and dynamic content editing
A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!
How to customize formatting for each rich text
Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
