REQUIREMENTS You need to design a programming module PERMISSIONS that would allow Caller to Grant a permission to a user Check if a user has a particular permission Caller is an external system that uses our module (particularly it calls our API). Permission is a user right to take an action or access a resource. Permissions for resource access can be READ or WRITE. For example, Caller can grant a permission ”reboot the server” (an example of action) OR write to a file “C:/[login to view URL]” (an example of resource) to a user Andrew. Caller can grant permissions directly to a user OR via roles. If Caller wants to grant permissions via roles then Caller needs to register a role, grant permissions to the role and then assign the role to a user. Caller can assign many roles to a user. As a note, our module (you are designing) doesn’t provide any dictionaries to Caller. All objects (including Users) are created / managed by Caller. Our module provides ONLY functionality. OUTCOME NOTE: You don’t have to strictly use a specific programming language for the exercise. You can use just a meta syntax that would give us an idea of your solution - we’re not going to compile it for sure :). We would expect you to write module API (a list of functions with parameters) and design a database for the module. A list of functions can look like this: function AddEmployee(company, first_name, last_name, age): boolean; function AddJob(company, first_name, last_name, age): boolean; function IsEmployeeFired(employeeId): boolean; ... If you want to pass an object as a parameter you can describe an object separately: Class Company { String name; String address; Integer taxId; } Database design can be presented as a list of tables with most important fields (no need to define indexes, etc). For example, Table Companies { Id, Name, Address, TaxId } Table Employees { Id, CompanyId, // this is a foreign key to Company FirstName, LastName, Job } Please apply If you can do this in shor time. I am looking for only expert in Ruby on Rails.
