Introduction to Data Science and Machine Learning:

The field of data science is an interdisciplinary field that mines raw data. After that, careful analysis is done on it, and various patterns are derived from the same that are used to extract valuable insights from the data. Statistics, computer science, machine learning, deep learning, data analysis, data visualization, and various other technologies form the core foundation of data science.
On the other hand, Machine Learning is primarily a set of techniques that are used by data scientists to train computers to learn from data. These techniques produce results that perform well without programming explicit rules. The field of Machine…

A Guide of How to Enable CORS in ASP.NET Web API

Introduction:-

ASP.NET is a framework for developing web applications that expands the .NET platform with tools and libraries. WebAPI for ASP.NET is a popular technology.

Everyone is attempting to use AJAX requests or the server side to access the service. Your web browser is unable to make AJAX requests to a server in another domain due to security limitations in your browser’s security policy. This is often referred to as the “same-origin scheme.”

Introduction:

The majority of firms have begun to become data-driven in recent years. This implies they use data-driven decision-making to design future plans for departments like marketing, growth, business development, and product development, among others. Businesses must ensure that the essential data is collected in a format that is suitable for analysis and is easily available in order to undertake an accurate analysis. Because the goal is to provide an accurate analysis, a large amount of data is collected, making storage on a single system unfeasible. Database Sharding was born as a result of this.

What is Serialization

Serialization in java is the process of converting the state of an object into a byte stream, which can be saved as a file on the local disk or sent, over the network, to another machine.

And de-serialization is the opposite of this process where actual objects are recreated using a byte stream.
(Sometimes the process of serialization and deserialization together are also termed serialization.)

The concept can be understood using the following serialization example in java :
Suppose, two friends are working together on a library management project in java. …
