Questions
- Considering this scenario, how would you store device data in the database? given that the API does not allow 1000 requests per second, and devices do not have direct access to the database;

- Which databases would be considered? Why? given the scenario where we only care about the last day (however, we need to keep the data history for analysis)

- How would you store the analytical data? which database? (no need to worry about calculations)

- How would you return analytics data to dashboards? (no need to worry about calculations)

.Net/Core

1. How does the .NET framework work? .NET framework-based applications that are written in supportive languages like C#, F#, or Visual basic are compiled to Common Intermediate Language (CIL). Compiled code is stored in the form of an assembly file that has a .dll or .exe file extension. When the .NET application runs, Common Language Runtime (CLR) takes the assembly file and converts the CIL into machine code with the help of the Just In Time(JIT) compiler. Now, this machine code can execute on the specific architecture of the computer it is running on.
2. What is .NET core? .NET Core can be said as the newer version of the .NET Framework. It is a cost-free, general-purpose, open-source application development platform provided by Microsoft. It is a cross-platform framework because it runs on various operating systems such as Windows, Linux, and macOS. This Framework can be used to develop applications like mobile, web, IoT, machine learning, game, cloud, microservices, etc. It consists of impor

Scenario:

- We will have 1000 devices capturing the user's heart rate, with 1 check per second;
- each device captures geolocation (latitude, longitude), user (name and age), device, date, heart rate;
- Doctors are only interested in all data of the last day (current day is not important in this scenario)
- Doctors need analytics dashboards with data by age and by user (from the last day - not considering today)
