How can you improve your database development portfolio using industry standards and best practices?

Some of the points that can be considered ate below ? Understand Database Fundamentals ? Learn SQL Thoroughly ? Database Design ? Focus on database design principles such as normalization ? Use Version Control ? Implement version control for your database schema ? Follow Best Practices ? Adhere to industry best practices for database development, such as writing clean, efficient SQL code, avoiding the use of SELECT *, and using appropriate data types ? Optimize Performance ? Understand and apply performance optimization techniques, including query optimization, indexing, and caching. Profiling tools can help identify and address performance bottlenecks ? Security ? Data Migration and ETL ? Testing ? Scalability

A lot of times one starts at a company where there are already databases all over the place and often they are in a really bad shape. It is often required to be able to identify problems in the data model, clean up data and find performance bottlenecks together with being able to propose solutions to get them in a better shape. Such projects and tasks are very valuable especially when a business needs to scale fast.

Using industry standards and best practises, you can improve your database development portfolio by taking into account the following: Credentials: Obtain pertinent credentials such as Microsoft Certified: Azure Database Administrator or Oracle Certified Professional (OCP). Continuous Learning: Attend conferences, webinars, and seminars to stay current on database trends and technology. Practical Experience: Engage in actual projects while exploring with various tools and database systems. Cooperation: Work together with seasoned experts to benefit from their knowledge. Open source: Contribute to open-source projects on GitHub or start own to demonstrate your expertise. Documentation: Compile thorough case studies and documentation.

To enhance your database development portfolio, gain proficiency in both SQL and NoSQL databases, stay updated with current normalization techniques and data modeling tools, and demonstrate the use of advanced features for optimization. Prioritize security through techniques like encryption and using prepared statements to ward off SQL injections. Earn relevant industry certifications and engage in code reviews and real-world projects. Always provide clear documentation to underscore your dedication to best practices and effective collaboration. This holistic approach will boost your portfolio's quality and appeal to potential employers or clients.

Increasingly, I would also focus on data(base) migrations as having this experience will be highly sought after by companies migrating from on-prem to the cloud (for example)

Some of the suggestions here are aimed at software development in my view. In a database context, I think it would be better to highlight: * Understanding of normalised vs denormalised schema design * Understanding of well-designed indexes * Pros and cons of stored procedures (for example) - versioning, deployment etc

Being able to explain how your work has improved efficiency, usability, scalability and durability of a database would be the key factors to highlight in my view

This is a given - especially if experience extends to new databases or database concepts like sql and nosql for example. Having a broad portfolio is far more attractive to most employers than being an expert in one specific RDBMS type for example.
