What is the difference between Database and Data Source?
733
Data are observations or measurements (unprocessed or processed) represented as text, numbers, or multimedia. A dataset is a structured collection of data generally associated with a unique body of work. A database is an organized collection of data stored as multiple datasets.
Concretely, a data source may be a database, a flat file, live measurements from physical devices, scraped web data, or any of the myriad static and streaming data services which abound across the internet.
What are the differences between a database and a data warehouse? A database is any collection of data organized for storage, accessibility, and retrieval. A data warehouse is a type of database the integrates copies of transaction data from disparate source systems and provisions them for analytical use.
In computing, a data source name (DSN, sometimes known as a database source name, though "data sources" can comprise other repositories apart from databases) is a string that has an associated data structure used to describe a connection to a data source.
A data source is simply something your program relies on to get data. A database is a kind of data source that persists data to some digitized form. Other data sources include files, services, etc — these all provide data to your programs.
