Answer 1

Maybe this viewpoint can help you: Basically Data Warehouse is an architecture, while Big Data is a technology. The first one became a well-known trend in the recent 20 years, while the latter one gained popularity only in the last decade.

Big Data and Data Warehouse are both used for reporting and can be called subject-oriented technologies. This means that they are aimed to provide information about a certain subject (f.e. a customer, supplier, employee or even a product). Data Warehouse is more advanced when it comes to holistic data analysis, while the main advantage of Big Data is that you can gather and process information from almost all well-known sources (f.e. social media or even specific machine data).
