Assignment

A small and very simple web application could be developed to keep product versions and installations of each version to customers. Each version and each installation have its details (notes).

Data models

class User {
    Id,
    FirstName,
    LastName,
    Email
}

class Product {
    Id,
    Name
}

class Customer {
    Id,
    Name,
    Description,
    Country
}

class Version {
    Id,
    ReleaseDate,
    ProductId,
    VersionNumber,
    Description
}

class VersionNoteType {
    Id,
    Name
}

class VersionNotes {
    Id,
    VersionId,
    UserId,
    VersionNoteTypeId,
    Description
}

class Installation {
    Id,
    CustomerId,
    VersionId,
    RefDate
}

class InstallationNotes {
    Id,
    InstallationId,
    UserId,
    Name,
    Description
}

Details about data models

• User is the application user. Each class member is a user.
• 1 product can be used for simplicity, e.g. “Axia”.
• 5 customers should be enough for the exercise.
• 10 versions should be enough for the exercise.
• Version Note Type could not change (static data) and could be one of the following: Module or Bug Fix
• Up to 4 notes per version should be enough for the exercise.

View Models

View models should be slightly different. The model Ids should be kept hidden but included in the models.

Application Views

• CRUD operations for all models
• Search for a customer and see installations and their notes (details)
• Search for a specific version and see basic information its notes
• Search using a period and check how many and which versions have been released within that period
• Search using a period and check how many installations were accomplished within that period

API is not necessary if mockup data exist in JSON files
