# Synchronous-Applications
Monolithic applications are a type of software where all components of the system (e.g., user interface, business logic, and database) are integrated into a single, unified structure. In this architecture, all the components run as part of one application.
---
### Features of Monolithic Applications
- **Unified Structure:**
All components (frontend, backend, and database) are contained in a single executable or process.
- **Simple Development and Deployment:**
Developers manage a single codebase, making development and deployment straightforward.
- **Good Performance for Small-Scale Projects:**
Suitable for small or medium-sized projects where speed and simplicity are priorities.
- **High Component Dependency:**
Even small changes can require rebuilding and redeploying the entire application.
---
### Advantages of Monolithic Applications
- **Simpler Initial Development:**
Easier to start for small projects as there’s no need to implement separate services.
- **Easier to Manage:**
One codebase and one deployment for the entire application.
- **Ideal for Small Teams:**
Suitable for teams that don’t require splitting services.
- **High Performance for Simple Requests:**
No inter-service communication means faster response times.
---
### Disadvantages of Monolithic Applications
1. **Difficult Scalability:**
For large projects, scaling or modifying parts of the system often requires rewriting significant portions of code.
2. **High Risk of Changes:**
Small changes can impact the functionality of the entire system.
3. **Complex Management for Large Teams:**
Managing a large codebase becomes challenging for big development teams.
4. **Long Deployment Times:**
As the application grows, compile and deployment times increase.
---
### When to Use Monolithic Applications?
- **Small to Medium Projects:**
When the project is small and doesn’t require extensive scalability.
- **Small Development Teams:**
When the team is small, and splitting tasks would create unnecessary complexity.
- **Limited Timeframe:**
When the project needs to be delivered quickly.

### **Building a Monolithic Application with Django**
Django is designed by default to create monolithic applications, making it straightforward to build a comprehensive application where all parts, such as business logic, presentation layer, and database management, are integrated into a single structure.
---
### **Steps to Build a Monolithic Application in Django**
### **1. Create a Django Project**
First, create a new Django project, which sets up the overall structure of your application.
```bash
django-admin startproject myproject
cd myproject
```
---
### **2. Create Apps**
In a monolithic architecture, each app is responsible for a specific part of the project, but all apps reside within a shared codebase and are interconnected.
```bash
python manage.py startapp blog
python manage.py startapp shop
```
- **Blog App:** Manages posts and articles.
- **Shop App:** Manages products and purchases.
---
### **3. Initial Settings in `settings.py`**
Add the newly created apps to the `settings.py` file.
```python
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'blog',
'shop',
]
```
---
### **4. Define Models**
Each app defines models related to its functionality. These models directly connect to the database.
### **Blog App (`models.py`):**
```python
from django.db import models
class Post(models.Model):
title = models.CharField(max_length=200)
content = models.TextField()
created_at = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.title
```
### **Shop App (`models.py`):**
```python
from django.db import models
class Product(models.Model):
name = models.CharField(max_length=100)
price = models.DecimalField(max_digits=10, decimal_places=2)
description = models.TextField()
def __str__(self):
return self.name
```
---
### **5. Database Management**
Migrate the models to the database:
```bash
python manage.py makemigrations
python manage.py migrate
```
---
### **6. Define URLs**
Define the routes for your apps in the project’s `urls.py` file.
### **`myproject/urls.py`:**
```python
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('blog/', include('blog.urls')), # Blog App URL
path('shop/', include('shop.urls')), # Shop App URL
]
```
### **`blog/urls.py`:**
```python
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name='blog_index'),
]
```
### **`shop/urls.py`:**
```python
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name='shop_index'),
]
```
---
### **7. Create Views**
Views handle requests and send responses.
### **Blog App (`views.py`):**
```python
from django.shortcuts import render
from .models import Post
def index(request):
posts = Post.objects.all()
return render(request, 'blog/index.html', {'posts': posts})
```
### **Shop App (`views.py`):**
```python
from django.shortcuts import render
from .models import Product
def index(request):
products = Product.objects.all()
return render(request, 'shop/index.html', {'products': products})
```
---
### **8. Create Templates**
Define templates to display data in your applications.
### **Blog Template (`blog/templates/blog/index.html`):**
```html
Blog Posts
- {{ post.title }}
{% for post in posts %}
{% endfor %}
```
### **Shop Template (`shop/templates/shop/index.html`):**
```html
Shop Products
- {{ product.name }} - ${{ product.price }}
{% for product in products %}
{% endfor %}
```
---
### **9. Run the Server and Test the Project**
Run the Django server and test your application:
```bash
python manage.py runserver
```
- Open `http://127.0.0.1:8000/blog/` to view the blog posts.
- Open `http://127.0.0.1:8000/shop/` to view the products.

### **Advantages and Disadvantages of This Approach in Django**
### **Advantages:**
1. **Simplicity in Development:**All parts of the project are in a single manageable structure.
2. **Complete Integration:**All components are directly connected without the complexity of inter-service communication.
### **Disadvantages:**
1. **Limited Scalability:**As the project grows, managing the codebase becomes more challenging.
2. **High Risk:**An error in one part can impact the entire system.
