Sempre que possível avalie o custo das query´s executadas por sua aplicação, nem sempre uma query da maneira como é montada e executada trará a melhor performance e o menor custo, hoje em dia aplicações precisam ser escaláveis, com isso devemos manter consultas com baixo custo, possibilitando uma melhor performance e trazendo ganhos e escalabilidade para suas aplicações. Quando precisamos relacionar dados e precisamos exibir registros, exige-se conhecimento de subquerys e relacionamento entre tabelas como left join, inner join ou rigth join. Boa sorte.

Mastering SQL is as much as knowing functions and syntax as it is being exposed to the real world craziness that you see at any job at any company. True mastery is being able to take anyone else's query that is on production running for 3 to 6 hours and reducing that by half with a few query execution plans or changing from sub select to CTE. You cant go from junior to senior without working. No amount of online courses or Youtube videos helps. ChatGPT is a production level tool though, use it daily to help speed up work.

To excel in database engineering, mastering SQL is crucial. It's the standard for database management. As a junior, aim for fluency, crafting complex queries effortlessly, grasping execution plans, and optimizing performance. Practice on real-world scenarios, engage in online SQL challenges, and review code from experienced peers. Efficient data manipulation is key to your value as a database engineer.

Mastering SQL is a pivotal step in advancing from a junior to a senior role in the realm of data management and analysis. SQL proficiency enables professionals to efficiently interact with databases, retrieve complex data sets, and perform intricate manipulations and analyses. Beyond basic querying skills, a deep understanding of advanced SQL concepts such as window functions, common table expressions, and complex joins is essential for tackling sophisticated data challenges. Senior-level roles often involve designing and optimizing databases, crafting intricate queries for data-driven decision-making, and architecting scalable data solutions.

I've been there myself, from wrangling junior tasks to senior engineer. According to me , sure up your SQL game, especially advanced stuff and how to make queries scream. Don't be afraid to dive into new tech, like cloud databases and NoSQL. However, it's not all about the code. Sharpen your communication skills to break down database complexities for anyone. Also,Learn to mentor junior engineers, be a knowledge fountain. Finally, take charge! Propose improvements and show you're ready to lead the pack. That'll get you noticed for senior roles for sure.

Always you must be cross functional expert in all products to be more realistic and understand the requirements. Then only you will be able to provide exact requirements to stakeholders

In the world of fast growing data, we need to make sure we cover all the grounds. DBMS is like the foundation of any database. Be it SQL or Mongo, it doesn't matter. As a developer we need to understand what to choose when the time you hear the requirement.

I find this topic somewhat controversial. Getting very familiar with a particular DBMS can be valuable, but implementing and relying on quirky DBMS features may be harmful in the long run. For example, multiple result sets in Microsoft SQL Server. It's pretty tough working with such a feature, and many database drivers in different languages don't even support it at all. I would recommend focusing on common behavior of different DBMS first, so you can easily switch and migrate between them, and use specific features only as last resort when you are sure that you will be using this technology for a really long time.

Puedes aprender con cualquier DBMS que exista en el mercado, el que más se ajuste a las necesidades. Pero será crucial entender en profundidad el lenguaje ANSI SQL que se rige toda DBMS

Learn the differences between RDBMS and non RDBMS databases. Then get to know the features of databases in RDBMS, which provider provides which features Oracle PostgreSQL MySQL Non RDBMS -- MongoDB Cassandra

With experience in MySQL, PostgreSQL, and Oracle, I’ve built a strong foundation in managing and administering different types of databases. To advance, gain hands-on experience with a variety of DBMS to understand their unique features and best use cases. Learn about advanced features like replication, partitioning, and clustering to manage large-scale databases effectively. Consider obtaining certifications from vendors like Oracle, Microsoft, or AWS to validate your skills and knowledge formally. This diverse exposure and formal recognition will prepare you for senior roles.

I find this subject controversial. Getting familiar with a particular DBMS is helpful, but using specific features can be harmful in the long run. For example, multiple result sets in SQL Server cause compatibility issues. It is best to focus on behaviors common to DBMSs and use specific features only as a last resort.

Proficiency with a range of Database Management Systems (DBMS) is essential. As a junior engineer, you likely have experience with one or two systems, such as MySQL or PostgreSQL. To progress in your career, it is important to expand your knowledge to include other popular systems like Oracle and Microsoft SQL Server. Familiarizing yourself with the unique features and limitations of each DBMS will enhance your versatility and equip you to handle a broader spectrum of projects and challenges.

Tough topic since DBMS change so much nowadays due to cloud based SaaS solutions. Being senior in one or two specific technologies combined with staying up to date with completely new platforms such as MS Fabric is a good building block so one can easily extend their expertise to other platforms as well.

Believe me, poor design the is the first reason of a failure project. An efficient system should be scalable, reliable, flexible and most importantly realistic. Don't go fancy but keep a room for flexibility. Don't be afraid of data redundancy if it adds performance, reliability and stability to the application. So application knowledge is most important in developing a good design.

This is, probably, the most important topic of them all. Not only you should think about the schema and the data structure, but also about the type of database itself. Many people still use RDBMS for every data storing task (and, sadly, in order to keep their popularity and client bases, many RDBMS start adding half-baked esoteric ways of storing data to compete with different NoSQL solutions). This is not an optimal approach. Foremost, start by thinking about what data will you be storing, what will the most common queries look like, what load do you expect to handle, how this load can increase in the future, etc. Depending on this, you can choose your storage type and its schema.

Delving into data modeling, normalization, and schema design enhances performance and scalability. The ability to create efficient databases stands out in leadership roles.

Typical step from junior to senior is the role change from being “just” a Data Engineer to being a solution or data architect. Very helpful in becoming more senior and of course also much more interesting for personal development from my point of view. Even nowadays I think the best way to gain knowledge in data architecture is via good old books.

Design is one of the key aspects. Work closely with the people involved in the project to understand the current requirements and future prospects. Deepen your understanding of pros and cons of Schemaless vs structured databases and where to use either of them. Further the compression and usage of various databases might be different as per usage software (back-end) vs ML. All of these points should be kept in mind to develop a scalable and flexible system. Do not add unnecessary complexities until they are absolutely necessary, simpler designs are better, easy to scale and debug.

Una base de datos bien diseñada reduce la redundancia, mejora la integridad de los datos y optimiza el rendimiento. Diseñar bases de datos eficientes te destacará

Es muy importante a la hora de diseñar un modelo de base de datos, eliminar la redundancia de datos y sobre todo, crear entidades con atributos bien definidos para evitar registros con puros NULL (ausencia de dato que no es lo mismo que vacío). Un buen diseño de base de datos, garantiza no solo el éxito de un proyecto, sino que evita más de un dolor de cabeza a nivel técnico.

In my career, I’ve been involved in designing efficient database schemas, ensuring proper normalization, and creating robust indexing strategies to support scalable applications. Deepen your knowledge of database normalization and denormalization principles to design efficient and scalable schemas. Understand how to use different types of indexes effectively to improve query performance. Practice creating entity-relationship diagrams (ERDs) to visually represent database structures, which helps in better planning and communication. This will ensure your designs are both effective and scalable.

In-depth study of data modeling, normalization, and schema design optimizes system performance and scalability. Mastery of these skills is a major asset for leadership roles, allowing you to create effective databases.

Database design is critical to achieving performance and scalability. As you strive for a senior role, it is important to deepen your understanding of data modeling, normalization, and schema design. Master the ability to identify when to denormalize data and how to use indexing effectively. A well-designed database minimizes redundancy, enhances data integrity, and boosts performance. Your expertise in designing efficient databases will distinguish you as a strong candidate for senior positions.

Not everyone have to embrace the cloud. Despite the hype, cloud databases also have their pitfalls. Many cloud providers offer easy to manage storage solutions, and they are great for reducing management complexity and increasing cost-efficiency. But sometimes you will need more fine-grained control of your databases and their configuration. Cloud solutions are prone to network problems, which you can't always fix by yourselves. Also, cloud solutions have some overhead of setting up the cloud environment properly, so good old hardware servers may beneficial in many situations.

Understanding all aspects of Cloud infrastructure and operations surrounding the database components such as PaaS, SQL Managed instance, connectivity issues , authentication etc.

Basic understanding of the cloud with the features gives you the edge. As a DBA, be aware of the features which we use like Storage, Backup types , High Availability, DR , region where our DB is residing etc

Absolutely, understanding cloud-based database solutions is essential in today's tech landscape. Platforms like Amazon RDS and Azure SQL Database offer scalability, flexibility, and convenience. Learning to migrate databases to the cloud, manage backups, and implement security measures are valuable skills. As organizations increasingly adopt cloud technologies, being proficient in cloud-based database management will indeed keep you relevant and in demand.

I have integrated cloud-based solutions into my database projects, leveraging the scalability and flexibility of platforms like AWS, Azure, and Google Cloud. To advance, familiarize yourself with cloud database services like Amazon RDS, Azure SQL Database, and Google Cloud Spanner. Learn how to migrate on-premises databases to the cloud, including data transfer methods, security considerations, and cost optimization. Pursue cloud certifications, such as AWS Certified Database - Specialty or Microsoft Certified: Azure Database Administrator, to strengthen your credentials in cloud technologies.

Lots of companies offer Visual Studio Subscriptions that come with free Azure credits. In that way one can easily try out cloud services and play around with it in a sandbox environment.

I recommend quite a no-brainer: stepping out of your comfort zone is key. Whenever I felt that I don’t want to do any presentation or being in the lead with a topic in an organization it turned out to be the best decision to just do it.

I would go to the extent of saying they are not soft skills. They are absolutely equally important as your core (technical) skills. They help you communicate your solutions, understand requirements etc.

I recommend quite a no-brainer: stepping out of your comfort zone is key. Whenever I felt that I don’t want to do any presentation or being in the lead with a topic in an organization it turned out to be the best decision to just do it.

It's absolutely crucial to discuss the details with the stakeholders and the business. Mistakes made because of misunderstandings on these stages will be most expensive (and sometimes even impossible to fix) on later stages of the project. Because of this, engineers need to constantly be in touch not only with each other, but also with business analysts in order to lay a strong technical foundation.

Effective communication and collaboration have been crucial in my role, especially when working with cross-functional teams and explaining complex database concepts to non-technical stakeholders. Improve your ability to convey technical information in a clear and concise manner to different audiences. Develop strong documentation practices to ensure that your work is understandable and maintainable by others. Cultivate good teamwork skills by actively participating in team projects, offering help, and sharing knowledge. These soft skills are essential for leadership roles and successful project execution.

It is absolutely crucial to discuss the details with stakeholders and the business. Errors due to misunderstandings at this stage can be costly or impossible to correct later. For this reason, engineers must stay in constant contact not only with each other, but also with business analysts, in order to establish a solid technical foundation.

Certainly, here's a refined version: While technical expertise is essential, soft skills are equally crucial. As a senior database engineer, you will be expected to lead projects, communicate effectively with stakeholders, and mentor junior team members. Focus on developing your communication, problem-solving, and leadership abilities. Engage in cross-functional projects to gain a broader understanding of the business context of your work. These skills will enable you to navigate complex projects and lead teams successfully.

One of the worst things you can do is rest on your laurels. In technology, it is extremely important to stay ahead of the curve (or at least keep up with it). New technologies come out every day and can quickly make your current experience obsolete. Invest as much as you can into your own personal development. Take advantage of every continuing education program that your employer has.

Try connecting with the latest newsletters and connect some technical talks by experts. There will be sessions where we can explore what is happening in real-time and the challenges in our database versions.

Check what's new in the new software versions. They usually contain solutions for previous problems, what most probably in current version have poor implementation.

Obviously if you would improve your own skills in any professional area, you should stay proactive and get dive into it. Participate in new courses and at any revelant professional gatherings where meanwhile you build your network (which is currently your net-worth) you can get more revelant and update infos about new ideas or if something would be debunked.

Staying updated with the latest industry trends and advancements has always been a priority for me, ensuring that I remain at the forefront of database technology. Regularly read industry blogs, attend webinars, and take online courses to keep your knowledge up-to-date. Join professional communities, attend conferences, and engage in forums to learn from peers and experts. Experiment with new tools and technologies in your projects to gain hands-on experience. Keeping current with industry developments will ensure you are prepared to implement the latest advancements in your work.

Always all field of IT evolving with new features and advancements. As IT professionals we jave to be adaptive and learning through out our career to gain that knowledge always.

Work closely with software developers A senior database administrator should work proactively with the software team to use the databases he/she manages in the most efficient way.

Throughout my career, I’ve found that continuous improvement, seeking mentorship, and taking on leadership roles have been vital to my growth and advancement. Be proactive in identifying and solving database-related issues, showing your value to the organization. Seek mentors who can provide guidance and share their experiences, and also mentor junior colleagues to reinforce your own knowledge.
