Transactional Websites-

Websites which carry out a purchase between a customer and the company providing the goods or services.
They collect details from the customer and collect payment-
Some people use pay pal instead of direct credit card payment, pay pal is a feature linked up with eBay. It is an intermediary between the customer and the company.

Databases play a big role in these websites to store all of the customer’s information, like payment details, names, phone number and address. It might be details of what you have already purchased from the company, like a purchase history record, showing how much you have spent as a customer so the company can keep track if the payment hasn’t come through. Furthermore, they could have a database to keep on track of all the stock they have.

Data is often useless without information.

In order for organisations to function, they need to store and communicate information. Information they need on a daily basis is email addresses to keep their customers informed etc. Websites like Amazon will also need information such as addresses, what is in stock and what isn’t and the quantity.

People say that information is the most valuable thing for a company as it can give them a competitive edge. Business can succeed or fail depending on how effective they are in information handling.
Information is extremely vital for hospitals and police as in hospital, if information about patients is lost about previous treatments or allergies, then this could lead to major problems with correct prescriptions and treatments.
If police databases were lost, then they would have no record of the criminals they have to keep track of, and all the information they need for detective work.

Data – collection of facts. What we input into computers is all data. Data is often useless with out information to back it up.
Information – is what humans want, it is output from a computer system. It is data in context, it has meaning to us but not to the computer, a computer only understands data.
Knowledge - it is coherent understanding based on information. It includes understanding links between different items of information and how actions can be decided.

Data capture is a process of getting data information from the outside world and putting it onto a computer.
