@Yndira-FlowForge what do you think?

The image doesn't have the right proportions; it should be a 1600 × 900 px image. As for the content, is it meaningful to people reading this article? We're usually more 'metaphorical' when creating these images.

@Yndira-FlowForge Can you create a tile for this post? That seems indeed a better choice

+# What exactly is Postgresql?
+
+PostgreSQL is an open-source database with a strong reputation for its reliability, flexibility, and support of open technical standards. Unlike other Relational Database Management Systems PostgreSQL supports both non-relational and relational data types. This makes it one of the most compliant, stable, and mature relational databases available today.


What open standards? The over the wire protocol for PG is unique, and the SQL support is a dialect too?

I apologize for the unclear introduction. Let me replace it with a clear and polished introduction.

Can we use alt tags to tell users what the difference is?

+2. Environment Variables: The [Twelve Factors](https://12factor.net/) emphasize the importance of separating configuration from code(flow) to ensure better security. Storing database credentials within the codebase can pose a security risk. Instead, expose the configuration details, as environment variables. This ensures that sensitive information remains secure and can be managed separately from the codebase.
+
+3. Primary Key Types: Choosing the appropriate data type for primary keys is crucial for database scalability and performance. While INT may suffice for small-scale applications, it's recommended to use BIGINT or UUID as primary keys for larger datasets. BIGINT offers a larger storage capacity and is more suitable for long-term scalability without the need for frequent migrations.


This makes little sense, an INT is 4 bytes, or 2^32! Just use a int with auto increment. Even a UUID is basically bull 💩 , over-engineered by engineers that think they build something that's Google scale next month. "Frequent migration"? It would be a one off?

Could you please tell me, ZJ, if it is necessary to add more points or if three points are sufficient for this best practices section?

Instead of recommending, it's better to point out limitations and assist the user in making a sound judgement. Int is +/- 2.4 billion.

Agreed, but I think we should keep the implementation as it is now, using integers. However, we should also include a brief note highlighting the limitations of integers to assist readers in making informed decisions.

@gdziuba can you pick up the review in my stead?

gdziuba · 2024-02-14T15:54:52Z

@ZJvandeWeg Yes. I will review.

Can we make the consistency of Ui vs ui vs UI across all. I would recommend calling it ui-group or equivalent.
