Here's how you can meet client expectations and deliver top-notch work as a freelance database developer.

In freelance database development, it's about teaming up with the client to create something valuable together. So, need to focus on understanding what they need and how our work can help achieve that goal through value co-creation.

* Get the requirement. * Spend as much time as you can to understand it without making any assumption. * Clarify every single question you have in your mind. * Don't just focus on achieving the end result. Get the feedback from client frequently presenting what you have done so far.

Begin each project by thoroughly understanding the client’s needs and the specific requirements of their database system. This involves asking detailed questions during initial meetings and carefully listening to the client’s responses. Clarify the scope of the project, the goals they aim to achieve, and any specific challenges they are facing. A deep understanding of these aspects will help you tailor your solutions effectively.

To be able to meet a client's expectations in freelance database development. you need to understand the client's requirements. There should be clear communication to reduce any form of ambiguity in the client's expectations.

Be clear with your requirements, analyse it and strictly no assumptions. Get the requirements clarified at the initial level itself.

In a project where I was developing a customer database for a healthcare provider, I used Trello to manage tasks and Slack for daily communications. This setup allowed the client to see real-time progress and communicate any changes or additional requirements promptly.

Maintain clear and consistent communication throughout the project lifecycle. Provide regular updates and be transparent about any challenges or delays as soon as they arise. Effective communication also involves setting realistic expectations about delivery timelines, functionalities, and costs from the start, and keeping the client informed about any necessary adjustments along the way.

Do not blindly take in what is stated in the requirement. Suggestions can be given to improve it. Discuss the pros and cons of what is given, with the client. Note : do not argue with them. Document all that has been discussed for future reference.(MOM)

Communication is a crucial part of any project. Confirm what is asked and what is being delivered clearly. It's ok to confirm what you understand. I prefer emails, Microsoft teams

Clear communication enables you to keep abreast with your clients. It's important to stay in touch throughout the system design, development and implementation. It creates a good rapport and dependability.

For a project requiring extensive data analytics, I selected PostgreSQL for its powerful analytical capabilities. I used pgAdmin for managing the database and wrote Python scripts to automate data processing tasks. This approach improved efficiency and allowed for more complex queries to be handled seamlessly.

Utilize the best tools and technologies available to design, develop, and manage database systems. This includes using advanced development environments, database management systems, and version control tools. Leveraging these tools not only improves the quality and reliability of your work but also enhances your efficiency and ability to meet deadlines.

Based on the primary level of analysis come up with better leverage tools to improve the work. Have a discussion with your team, as the team members can provide some better ideas. Take in all the suggestions and unanimously come up with the decision and provide a demo to your higher officials and based on their approval provide a demo to the client. And give a kick start to your project

Prioritize the security of the databases you develop. Implement robust security measures to protect data integrity and confidentiality. This can include using encryption, configuring firewalls, and ensuring proper access controls are in place. Educating your client about the importance of these security measures and how they are implemented will also help in managing their expectations and ensuring their peace of mind.

Any sort of project needs and holds confidential data. Added to the best leverage tools used for the project give equal importance to the security management of these data, where database credentials are much secured.

Penser à la sécurité au début même du cycle développement est la bonne chose à faire . Nous sommes à une époque où la moindre faille , le moindre défaut de conception pourrait entra?ner des conséquences graves .

Security and integrity are very important for customers when choosing a database, that's to say we should let customers know how to ensure security when the data is transported and stored, how to support the HA and DR, how to upgrade, and how to address the transaction failed, etc.

Ensure that the databases you create are optimized for performance. This involves structuring queries for efficiency, properly indexing databases, and conducting regular performance testing. Delivering a database that performs well under operational loads is crucial for client satisfaction and the overall success of the project.

Do not dumb in unnecessary data.Let your database have a better readability and monitor its performance and analysis , create the tables and schemas accordingly.

Database query optimization is essential for enhancing services and providing the best possible outcomes for users. This involves better data modeling and writing highly optimized queries. As the user base and database grow, we should employ techniques such as indexing, sharding, and partitioning to achieve the fastest and most efficient results. Key strategies include: Optimized Queries: Write efficient queries and make the best use of available resources. Indexing: Use indexes to speed up data retrieval operations. Sharding: Distribute the database across multiple servers to balance the load and improve performance. - Partitioning: Divide large tables into smaller, more manageable pieces to improve query performance and maintenance.

Performance is a concern in almost all project. We need to plan in such away, the performance should be maintained , in all kind of tests(stress, load, etc). Optimize queries, determine what may cause deadlock, what the environmental discrepancies.

Optimize for performance. Avoid n+1 queries. Index when necessary. Readability is key too. Cache when necessary so you don't hit the DB often for data that rarely changes.

It's never late to be upgrade yourself, Try to learn a new concept everyday. Understand which is the better tool than what is being used. Try to be updated with the new tools.

Keep your skills and knowledge up to date with the latest developments in database technology, security protocols, and best practices. Continuous learning allows you to offer the most current and effective solutions to your clients, setting you apart as a knowledgeable and competent professional in the field.

La veille technologique, certaines personnes semblent ne pas s’y intéresser et pourtant n’importe quel système censé évoluer dans notre époque ou une technologie créée aujourd’hui pourrait être obsolète dès demain. La chose à faire dans ce contexte serait de veiller à faire des migrations de version habituellement , cela non seulement vous permet cohérence mais aussi la sécurité.

Also learning similar database development platforms would help. When I learned PostgreSQL, I understood the extra features it provides compared to Microsoft SQL server. Even though there are few advantages of SQL server over PostgreSQL, however knowing different SQL technologies would help us to guide our client if required.

In all of my experience as a freelance developer I have rarely came across a database that was optimally designed. Many, especially those that have been in use for a longer period of time tend to be very unorganized. Many different developers have worked on different elements without considering the overall use and existing elements. Take the time to learn the database. Learn what is stored in it. Why it is there, and how it was developed. Make your solution to meet the requirements properly but at the same time make it look like it was built the same as the existing database.
