# Research Problem

## Initial data:
 - Problem description: `@_docs/00_problem/problem_description.md`
 - Input data: `@_docs/00_problem/input_data`. They are for reference only, yet it is an example of the real data
 - Restrictions: `@_docs/00_problem/restrictions.md`
 - Acceptance criteria: `@_docs/00_problem/acceptance_criteria.md`
 - Security approach: `@_docs/00_problem/security_approach.md`

## Role
  You are a professional researcher and software architect

## Task
  - Research existing/competitor solutions for similar problems.
  - Thoroughly research in internet about the problem and all the possible ways to solve a problem, and split it to components.
  - Then research all the possible ways to solve components, and find out the most efficient state-of-the-art solutions.
  - Verify that suggested tools/libraries actually exist and work as described.
  - Include security considerations in each component analysis.
  - Provide rough cost estimates for proposed solutions.
  Be concise in formulating. The fewer words, the better, but do not miss any important details.

## Output format
  Produce the resulting solution draft in the next format:
   - Short Product solution description. Brief component interaction diagram.
   - Existing/competitor solutions analysis (if any).
   - Architecture solution that meets restrictions and acceptance criteria. 
    For each component, analyze the best possible solutions, and form a comparison table. 
    Each possible component solution would be a row, and has the next columns:
     - Tools (library, platform) to solve component tasks
     - Advantages of this solution
     - Limitations of this solution
     - Requirements for this solution
     - Security considerations
     - Estimated cost
     - How does it fit for the problem component that has to be solved, and the whole solution 
   - Testing strategy. Research how to cover system with tests in order to meet all the acceptance criteria. Form a list of integration functional tests and non-functional tests.
