We finished covering the basics of interacting with data in different commonly used storage mechanisms from the simple ones, such as text files, over more structured ones, such as HDF5, to more sophisticated data storage systems, such as MongoDB and Redis. The most suitable type of storage will depend on your use case. The choice of the data storage layer technology plays an important role in the overall design of data processing systems. Sometimes, we need to combine various database systems to store our data, such as complexity of the data, performance of the system or computation requirements.
Practice exercise
Take a data set of your choice and design storage options for it. Consider text files, HDF5, a document database, and a data structure store as possible persistent options. Also evaluate how difficult (by some metric, for examples, how many lines of code) it would be to update or delete a specific item. Which storage type is the easiest to set up? Which storage type supports...
