In this article, I am going to discuss Amazon Athena and how we can analyze data stored in S3 using Athena. As you might know, Amazon’s AWS has a lot of services in the field compute, databases, analytics, machine learning, and robotics, one of the most important and popular services is Amazon Athena. By the official definition, “Amazon Athena is an interactive query service that makes it easy to analyze data in Amazon S3 using standard SQL. Athena is serverless, so there is no infrastructure to manage, and you pay only for the queries that you run.”

In our previously published article in this series, we explained how to migrate SQL Server graph tables into Neo4j and why migration could be beneficial. We only mentioned how to migrate node and edge tables, and we did not mention indexes and constraints. This article is an extension of the previous one, where we will explain how to export the supported indexes and constraints from SQL Server to the Neo4j graph database. In addition, all codes are added to the project we already published on GitHub.

In this article, I am going to talk in detail about the functions and arguments in Python. Python is one of the most popular and in-demand programming languages. Recently, a lot of programmers are gaining interest to work with python and as such, there is a huge community around it that is constantly evolving. Python is also considered to be one of the most flexible languages as it can be used to develop web-based applications, REST APIs as well as can also be used significantly in the scientific computation world to deal with data analysis and machine learning.

Azure SQL Database is an Infrastructure-as-a-Service component for migrating your on-premises SQL Server to cloud infrastructure. We always look for performance, cost, and scaling resources while we plan resources in the cloud. Many times, we do not want our databases running 24*7*365. Suppose you have a development or training database. Your developers work during the daytime on the weekdays. If you deploy an Azure SQL Database, you don’t get an option to stop it. You get charged for it whether you use it actively or not.

In this article, I am going to write about the various ways we can work with JSON data in Python. JSON stands for Java Script Object Notation and has become one of the most important data formats to store and transfer data across various systems. This is due to its easy-to-understand structure and also because it is very lightweight. You can easily write simple and nested data structures using JSON and it can be read by programs as well. In my opinion, JSON is much more human-readable as compared to XML, although both are used to store and transfer data. In modern web applications, by default JSON is being used to transfer information.

In this article, we will talk about two query optimization myths and these myths can be changed according to the characteristics of the queries. Every query can exhibit different behaviors according to data distribution, SQL Server version, database settings, and other tons of parameters therefore the fixed ideas may not help to overcome the query performance issues. In the next part of the article, we will focus on the following most known discourse:

In this article, I am going to introduce a few concepts of how to set up and get started with R and RStudio to perform machine learning workloads. It has always been the heat of the discussion on whether to choose Python or R for performing Machine Learning analysis. In my opinion, both the languages excel in their own space and there is no point-to-point comparison between the two directly. Mathematicians and statisticians like to work within the R environment, while programmers choose to work with Python.
