If you want to be a DBA you should first master SQL skills as it is the heart and soul of the databases. As a DBA you should be able to write and/or rewrite SQL queries written by other development teams to optimize the performance of queries and also the database on the whole. Work with developers some of them may be experienced and some of them may be fresh starters. You need to spend a lot of time fine tuning SQL queries to maintain the good health of the database.

SQL Mastery is more than just a guide; it's a journey that teaches a deep understanding of SQL. One compelling story is about a software developer who used the book to learn SQL for a new job. They were intimidated at first, but the book's clear explanations and practical exercises made it easy to grasp the concepts. Through the book, they were able to build a solid foundation in SQL, mastering complex queries and database management. This newfound knowledge enabled them to excel in their new role, highlighting how SQL Mastery can empower individuals in their professional journeys.

Formal training coupled with real-life experience is key to really harness the full potential of this platform, but it is not limited to that. Time and dedication. To assist on mastering a topic, teaching and explaining to your peers are 2 other actions that can be taken to measure your level of understanding of a topic and I am certainly recommending anyone on that journey to try. Let me know your thoughts !

Performance tuning of the databases is one of the most important tasks of the DBA. Performance tuning includes creating indexes on fields that are used inside the query. As a DBA I create a best practices document and share it with the development teams and make sure they follow it while writing SQL queries. These best practices may differ slightly from organization to organization based on the database configuration settings.

This is ever sort after skill. Even though its a mix of science and art, industry looks as a magic pill. This is the most slow, high impact area. Defining the scope is the key for success, as it does not have an end.

As a DBA it is your responsibility to ensure data backup strategies are taken care of in order to protect the data from any accidental changes done by developers. Since many companies are using cloud platforms for databases it is one way more secured and requires less interaction by DBA teams.

En base a mi experiencia, se implementar un proceso completo de Respaldo y Recuperación de Base de Datos. Se deben incluir pruebas periódicas de respaldo y recuperación de las bases de datos. Son importantes estrategias de respaldo y recuperación parciales ya que una restauración y recuperación completa de la base de datos puede ser muy compleja dependiendo del volumen y complejidad de cada base de datos.

In my experience the most requested skill for cloud services is AWS, so learn about DocumentDB, Aurora and DynamoDB, but don't forget to be proficient with cloud constructs like VPC and networking.

Its a most essential skill set, organizations are not hiring DBA for regular repetitive job. Automate all repetitive tasks, free up your time and do other useful, impactful things. One cannot automate everything, human intelligence is required in various aspects.

Tecnology is continually evolving, but basic skills don't change that much. Be sure to have strong basics and then expand, learn how to navigate the main cloud providers and their offerings, learn about security on your strongest DB, learn on how to automate things for the DB in languages like Python and processes like ETL.

Learn to perform trend analysis, understand where technology is heading. Today DRDBMS, NewSQL, TimeSeriesDB, VectorDB, RDF DB are in upswing, tomorrow something new will come, keep on learning.
