- Generation. The cycle starts with the generation of data. People generate data: Every search query we perform, link we click, movie we watch, book we read, picture we take, message we send, and place we go contribute to the massive digital footprint we each generate.
- Collection. After generation comes collection. Not all data generated is collected, perhaps out of choice because we do not need or want to or for practical reasons because the data streams in faster than we can process.
- Processing. After collection comes processing. Here I mean everything from data cleaning, data wrangling, and data formatting to data compression, for efficient storage, and data encryption, for secure storage.
- Storage. After processing comes storage. Here the bits are laid down in memory. Today we think of storage in terms of magnetic tape and hard disk drives, but in the future, especially for long-term, infrequently accessed storage, we will see novel uses of optical technology and even DNA storage devices.
