Lightweight implementation of Event Sourcing using PostgreSQL as an event store 🚀🕗🔙🕘
Tags: webdev, showdev, postgres, java
Published: 2023-10-31 12:52:18

Do you use the Event Sourcing pattern?
If you have a Java Spring Boot application with a PostgreSQL database, you can implement Event Sourcing without introducing new specialized databases or frameworks.

> **How do I know that I need the Event Sourcing pattern?**

If you have an application dealing with an entity called Order, you should adopt Event Sourcing to keep track of all changes, and know how the Order got into the current state.

Event Sourcing gives you:

1. the true history of the system (audit and traceability),
2. the ability to put the system in any prior state (debugging),
3. the ability to create read projections from events as needed to respond to new demands.

![Order entity CRUD vs Event Sourcing](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/5b1nlaejqk9b49hc8yok.png)

_Order entity CRUD vs Event Sourcing_

There are several well-known specialized frameworks and databases for Event Sourcing: EventStoreDB, Marten, Eventuate, to name a few.

> **Do I really need a specialized database and framework for Event Sourcing? It would be easier to convince colleagues and management to try Event Sourcing if there was a way to use an existing PostgreSQL database as an event store and implement the Event Sourcing pattern with several classes without specialized frameworks.**

Adopting a new framework or database you are not familiar with may stop you from trying the Event Sourcing pattern in your project. But you can actually implement Event Sourcing with a few classes and use PostgreSQL as an event store.

The [**postgresql-event-sourcing**](https://github.com/evgeniy-khist/postgresql-event-sourcing) project is a reference implementation of an event-sourced system that uses PostgreSQL as an event store built with Spring Boot. Fork the repository and use it as a template for your projects. Or clone the repository and run end-to-end tests to see how everything works together.

The project describes in detail:

- database model for storing events, 
- synchronous and asynchronous event handlers, 
- CQRS, 
- Transactional Outbox pattern, 
- Polling Publisher pattern, 
- optimized publisher that uses PostgreSQL LISTEN/NOTIFY capabilities,
- and more.

![PostgreSQL Event Sourcing](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/wweq0p8qic30mto8cymc.png)

_PostgreSQL Event Sourcing_

This project can be easily extended to comply with your domain model. Event sourcing related code and application specific code are located in separate Gradle subprojects:

- `postgresql-event-sourcing-core`: event sourcing and PostgreSQL related code, lightweight shared library,
- `event-sourcing-app`: application specific code, simplified ride-hailing sample.

To adapt the project to your domain model, make changes to `event-sourcing-app` subproject. No changes to `postgresql-event-sourcing-core` subproject are required.

The source code is available on [GitHub](https://github.com/eugene-khyst/postgresql-event-sourcing).
Dummy Variable Trap in Machine Learning
Tags: machinelearning, deeplearning, dataengineering, datapreprocessing
Published: 2023-10-31 12:51:15

Before we discuss **Dummy Variable Trap**, let's first go over what **Dummy Variables** are ?

As we all know, computers only understand 0's and 1's. So, what happens if we have data with categorical values, such as _India_ and the _United States_?

Yes, the machine can understand that, but it will have an impact on the accuracy of our machine learning model. So why not convert that data into numerical data by numerically representing common values?

Thus,

> The processing of encoding Categorical Data into Numerical Data is known as Dummy Variables.

**For example :**

![Categorical to Numerical Format Conversion](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/jxu7fmpel8syqoyti2yn.png)

As it's clearly shown in above representation that **_Dummy Variable is a Binary variable that takes values of 0's and 1's_**

**Dummy Variable Trap :**


> _Dummy Variable trap is a scenario where one or more than one dummy variables that are created are highly correlated(multi-collinear)._


We have established four dummy variables, each of which has **multicollinearity**, as seen in the diagram above. This means that it will have an impact on the machine learning model's performance.

> Multicollinearity is nothing but a statistical term  where several  Independent variables are correlated.


**How to handle Dummy Variable Trap ?**

Frameworks or built-in algorithms have already dealt with the Dummy Variable traps, so we don't need to do anything else.

But still If we want to do so, we can  remove one of the columns something like : 


![Had](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/d291ies5iby3ulwn4v89.png)

We can reduce multicollinearity and hence the dummy variable trap by eliminating a single column from the Dummy variables. But we no longer have to manage it ourselves; speedy and efficient machine learning algorithms do it beneath the hood.

Task 3: Functional and non-functional testing
Published: 2023-10-31 11:56:32

The software is tested for the functional requirements. The tests are written in order to check if the application behaves as expected. Although functional testing is often done toward the end of the development cycle, it can—and should, —be started much earlier. Individual components and processes can be tested early on, even before it’s possible to do functional testing on the entire system.
Functional testing covers how well the system executes the functions it is supposed to execute—including user commands, data manipulation, searches and business processes, user screens, and integrations. Functional testing covers the obvious surface type of functions, as well as the back-end operations
Black Box Testing: Testing based on an analysis of the specification of a piece of software without reference to its internal workings. The goal is to test how well the component conforms to the published requirements for the component.
Integration Testing: Sometimes, functional testing involves testing the integration of different components or modules to ensure that they work seamlessly together.
System Testing: Functional testing is often a part of system testing, where the entire system is tested to ensure that all components work together as a complete and integrated system.
Regression Testing: After changes are made to the software, functional testing helps ensure that existing functionalities are not negatively impacted.

Non-functional testing aims to assess how well the system performs under certain conditions and to ensure that it meets the expected non-functional requirements. It evaluates characteristics such as performance, reliability, usability, scalability, and other non-functional attributes.
Performance Testing: This involves testing the speed, responsiveness, and overall performance of the system. It can include load testing, stress testing, and scalability testing to assess how the system performs under different load and stress levels.
Security Testing: Security testing is conducted to identify vulnerabilities and weaknesses in the system's security. It includes testing for potential breaches, unauthorized access, and data protection measures.
