James Fielder Databases, Development Technologies, Programming Leave a Comment

Today, we are going to be going over a very useful tool called Sequelize. It is an Object Relational Mapper (ORM), which allows us to interact with relational databases using Node.js.

Braden Niswonger Development Technologies, GraphQL, JavaScript, Programming, React Leave a Comment

In this post, we will explore Apollo Client integrated with a React application and how it provides an abstraction layer between a JavaScript application and a GraphQL server. The features Apollo Client offers make it a prime choice for devs also using GraphQL.

We’ll begin by discussing what Apollo Client is and how it can be advantageous over other state management libraries. And finally, we will look at some example React queries for retrieving and mutating data.

Let’s get started.

In this video, Alex presents an introduction to data science “big ideas” relevant to the model, an explanation of its data modeling process, and a demonstration of the real-life machine learning solution implemented with Python, Postgres SQL, and H2O (an open-source machine learning algorithm). Multiple data sources and technologies were combined to create an accurate model that allows farmers and recreationists to make actionable insights about the future. A few questions and answers round out the discussion.
