Like any new skill, it can feel overwhelming to know how to start. Let's go step by step in breaking down the most valuable parts of learning SQL - 1. Identifying motivation - Before diving into learning SQL, it's important to understand your motivation. Why do you want to learn this skill? Which aspects of working with SQL excite me the most? 2. Learning the basics first - A . SELECT statements - The foundation for fetching data from a database. B. JOINs - How you combine rows from multiple tables based on a shared column. C. Subqueries - Handy for conducting complex queries within other SQL statements. By focusing on core skills,can build a strong foundation and stay motivated to keep learning.

Eu particularmente acho essencial a linguagem SQL eu tenho aprimorado minhas habilidades nessa linguagem criando views para minha datawarehouse, é de extrema importância.

SQL is essential for working with relational databases. Begin by mastering commands to create databases and tables, and practice writing queries to select, insert, update, and delete data. Learning JOIN operations is crucial, as they allow you to combine data across multiple tables, which is key in real-world scenarios. To strengthen your SQL skills, work on practical projects where you build and query databases to solve realistic problems. This hands-on approach will deepen your understanding and make you proficient in SQL’s core functionalities.

Mastering SQL is foundational for anyone working with relational databases. Start by setting up databases and tables with SQL commands, then focus on honing skills to retrieve, modify, and manage data effectively. Proficiency with JOIN operations is key to integrating data from multiple tables—this is a critical skill in real-world data scenarios. Strengthen your SQL abilities by tackling real-world data projects; building and querying databases will make your knowledge truly applicable and impactful.

Java, though not typical for data analysis, is powerful for performance-heavy tasks. Start by mastering core concepts—classes, objects, and inheritance—to understand Java’s object-oriented structure. Java is valuable in big data with technologies like Apache Hadoop and Apache Spark, which are used for distributed processing of large datasets. Libraries like Weka offer machine learning capabilities, and Java can integrate with other tools to support data analysis workflows. Building small projects that use these tools will clarify Java’s role in data-intensive applications and solidify your understanding.

Java might not be the go-to for data science, but its strengths in high-performance computing and scalability make it highly relevant in big data ecosystems like Hadoop and Spark.

In simple words , Eat Daily == Learn daily Habits to develop a continuous learning mindset - 1. Be curious - Curiosity is at the heart of all questions. Always ask questions — of yourself, of people you know, of the internet. When you don't understand something then ASK. Curiosity yields questions, asking questions yields answers. 2. Read - Reading is key to adult education, and is the best way to gain new perspectives, think differently, learn how others struggle and thrive, and expand your ideas of what's possible. Think of reading as a tree, with the reader moving from branch to branch. Simply read what interests you, stay open to finding new interests and work reading into your daily life.

Quando comecei a estudar para mudar para área, eu descobri diversas ferramentas. É comum as pessoas acharem que precisam saber de todas, mas é um engano. Atualmente eu foco em três ferramentas, sendo elas PBI, SQL e Python. E acho que melhor que estudar todas as outras ferramentas, é se especializar nestas para desempenhar um melhor resultado. As demais, como tableau, R, etc, futuramente terei o prazer de conhecer. Atualmente eu quero focar nessas por um período considerável. Acho que é essa é a melhor dica que alguém que está tentando ingressar na área de dados deveria receber, afinal, assim como as demais áreas profissionais, a área de dados necessita de estudo contínuo.
