The basic principles for User Interface design

1. Hierarchy: User should be able to distinguish between important and less important information at a glance. The UI hierarchy should highlight what the user cares about the most.
2. Contrast: To draw attention to important content or features.
3. Alignment: Proper alignment helps with readability.
4. Clarity: There should not be anything that will confuse the user. We should try to provide a design that user can understand easily by taking a glance at it.
5. White space: For a design to work better. It needs to have a adequate amount of space between it's content.

Add the `:environment` task as dependency for Rake task to access models.

desc "count number of users"
task :count_users do
  puts User. count # NameError: uninitialized constant User (NameError)
end

To make the models available, tell Rails to load the environment before running the task.
desc "count number of users"
task count_users: [:environment] do
  puts User. count
end

HIGH LEVEL DESIGN It is simply a blueprint for the system. In other words, a generic system design that describes the overall architecture and design of a system.

1. System - is a set of components put together to build a product/feature.
2. Feature - is a set of requirement to be satisfied. System Design is necessary to ensure that a system meets specific requirements, such as performance, reliability, scalability, and maintainability. Without a clear blueprint, a system may not work as intended, leading to performance issues in the future, downtime, etc.

High-level design also includes:

1. Overall Architecture.
2. Database design
3. Main Components
4. Services and platforms

How we can change the default Sqlite database to Postgresql database in Ruby on Rails , • Make sure homebrew is installed . • Install Postgresql , brew install postgresql • Start the postgresql , brew services start postgresql • Make changes to postgresql database in the database.yml file • Add rails db:seed to ensure your data gets reset and is visible on the browser .
