Your convention might state that “ID” should be the name for the primary key of each table. Using mixed representations, for example with dates a MMDDYYYY format and then a DD-MM-YYYY format, methods, functions, or other elements that consume or process this data will need to account for this. When you're using data that has variance in how it is represented, do not use multitudes of formats. In this blog I’ll go over some conventions I use to keep myself consistent. Keeping it simple, such as Id and Stamp are some of the recurring columsn that are useful for retrieval, relationships, and determining origins of data over time. Consistency, readability, maintainability, and extensibility are some of the most important factors when designing new databases. Using schemas to group objects with similar security requirements.

Similarly, conventions allow users to safely assume a pattern when accessing different items within your schemas. The diagram above, without any further details can be used to create the schema, with SQL code that would look like the following. I went a bit overboard and removed as many traces of a naming convention as I could. And finally it should be readable for programming language or framework that is implemented. Postgres names fold to lowercase versus uppercase, which is different then many other databases. In SQL, this is a bit different.
