big data

• characteristics of a data set classified as big data:

  very large volume (too much for one server), velocity at which data is generated, variety of data types in the data set
• why is functional programming appropriate for parallel computer architectures?

  in functional programming, data is immutable so different parts of the program wouldn't affect each other. Order of execution is less rigidly defined than in other paradigms.
• why is big data less compatible with procedural or object oriented paradigms?

  because of the large volume of data, multiple servers have to be used, therefore processing is also split over multiple machines. So parallel processing is required, which is more compatible with functional programming
