![Django Web Framework
• Django Project has multiple applications:
• Core application
• Module “applications” represent a single aspect of a project.
• DB: SQLite for development only (PostGres, MySQL, NoSQL)
• APPS are registered in the settings.py file:
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',

![Model: Economic Indicators
GDP:
Monetary measure of the market value of all final goods and
services produced in a period (quarterly or yearly) of time.
GNI:
Total domestic and foreign output claimed by residents of a
country, consisting of gross domestic product (GDP), plus factor
incomes earned by foreign residents, minus income earned in
the domestic economy by nonresidents.
FDI:
Investment in the form of a controlling ownership in
a business in one country by an entity based in another
country.[1].

- 2. What will I learn? How to: • Research and choose an API suited for your application • Use Postman for making requests to APIs • Construct query strings with parameters • Annotate and share Postman research • Start developing a Python Django Web App
- 6. Impact of API on Development For REST requests in JSON: • Is the correct type of data available? • Language? Currency? Year-Range? • Are there examples of query strings/calls? • Are the endpoints well documented? • Are the parameters clearly defined? • Is it easy to construct a query string? • How complex is the data object to parse in the program? • Should I implement client-side caching of API calls? • 100% Uptime/Availability?
- 9. Our prototype must show GDP/PIL in Italy GDP: Monetary measure of the market value of all final goods and services produced in a period (quarterly or yearly) of time. Nominal GDP estimates are commonly used to determine the economic performance of a whole country or region, and to make international comparisons.

- 24. MTV vs. MVC? Django uses MTV Model(M) is a model of the data access layer. It defines: - How to access data - How to validate data - What are the relationships between the data Template (T) is the presentation layer. It defines: - How something should be displayed on a Web page View (V) is the business logic layer. Defines the logic that: - Accesses the model and references the appropriate template(s).
