Описание тега sample-data
Sample data is a term used for publicly available sets of data in a variety of formats.
Sample data is used to get an application started quickly with data for demo purposes or to load test an application or database platform. The data held within may accurately represent a data set, such as a list of countries or be completely manufactured.
The idea is that is it not used as a basis of a good data sample, but merely useful as 'data'.
Examples include (but not limited to) CSV, Database Backups, Excel or plain text files. The OP would usually specify the format that they require in their question.
