Non Relational Data

Question 1

CSV

Answer 1

comma separated values. Data places commas beween each dield. This alleviates the issue of a data value that is longer than the fixed width issue. However the data is not human readable and is error prone

semistructured data format. Not as structured as relational data. XML can be used to exchange data and has the capability of human readable content with tags.
