My book "Patterns in Data Management" is now available both as an ebook or a print book (with color graphics!). See: amzn.to/1Ts3rwx This book is not a standard textbook on database techniques. This book was written extending and complementing preexisting educational videos (including this one).
What are the properties of ideal computer memory? What is the core idea of the storage hierarchy? What is the relationship of storage capacity and access time to the distance to the computing core? What is the relationship of costs/bandwidth to the distance to the computing core? What are typical access times? How does this translate to relative distances? What are typical sizes of the different storage levels? How do they translate to relative distances? What are the tasks of each level of the storage hierarchy? How would I use a storage hierarchy to cache only reads? How do I use a storage hierachy to cache both reads and writes? What is inclusion? What is a data replacement strategy?
