Explore the fundamentals of bits and bytes and their role in health care information systems. Discover data storage methods, data compression, databases, data management, and centralized versus distributed architectures.
Understand how bits and bytes encode digital data, how medical images are digitized into pixels with greyscale values, and how storage and network needs scale.
Traces storage media evolution from paper to cloud, explains fragmentation and defragmentation on hard drives, and contrasts magnetic disks with flash memory and a redundant array to handle cardiac imaging.
Explore how data compression reduces large healthcare data for faster transmission and storage, while balancing fidelity, artifacts, and the debate over raw versus compressed medical images.
Explore how databases separate structured and unstructured data, using records and fields, with examples from libraries, excel spreadsheets, and web search indexing for health care decisions.
Explore hierarchical storage management for health data, balancing online, near online, and offline storage—rapid access versus cost, with cloud archiving as a scalable tier.
Compare centralized and distributed storage architectures in healthcare. Centralized systems offer speed but risk a single point of failure; distributed storage adds redundancy and index across data centers for reliability.
Celebrate completing the course and applying the tools and skills you learned to your future endeavors.
HEALTHCARE RUNS ON DATA
Every electronic health record, medical image, laboratory result, prescription, and digital healthcare transaction ultimately comes down to data.
But what exactly is digital data? What are bits and bytes? Where is all that information stored? How can huge amounts of data be compressed, organized, retrieved, and managed? And why does any of this matter to someone working in healthcare?
You don't need to be an IT professional to understand the answers.
This course takes you behind the scenes of digital healthcare information and explains the fundamental technologies that make it possible—Plain & Simple.
WHAT YOU'LL LEARN
We'll start at the very beginning with bits and bytes and gradually build toward the larger systems used to store and manage healthcare information.
You'll explore:
Bits and bytes and how digital information is represented
Different types of data storage
Data compression and why it matters
Databases and how information is organized
The fundamentals of data management
Centralized versus distributed system architectures
How these concepts relate to healthcare information technology
You'll also have a quiz and assignment to reinforce what you've learned.
DIGITAL DATA—PLAIN & SIMPLE
This course is designed for healthcare professionals, managers, students, and business professionals who want to better understand the technology behind healthcare information. No technical background is required.
My approach is practical rather than highly technical. I spent 35 years designing, developing, and bringing medical technology to market, progressing from engineering leadership to VP of Marketing and ultimately president of a healthcare IT company. I've also spent many years teaching graduate-level university courses.
My goal isn't to turn you into an IT specialist. It's to give you enough understanding of digital data, storage, compression, databases, and system architecture to better understand how healthcare information systems actually work.
