- We use Place-Oriented Programming (PLOP): we know location of data in memory or database and use that to update it.
- This paradigm comes from the times we had really limited RAM and we had no other way to program. This was the only way to do programming.
- Since that times, the capacity grew million times bigger.
- When a thing grows a million times bigger, almost none of its characteristics remain. But we are still clinging to the Place-Oriented Programming.
- If we look at memory and records before computers, we see that they do not work by rewriting information.
- Memory does not work by replacing the old information.
- Records are usually append-only. If you make a mistake, you add a corrective entry (e.g., you don’t alter old records in double-entry accounting)
- Values are immutable
- Value Propositions
- values can be shared (because they are immutable, this is safe to do)
- reproducible results
- easy to fabricate (in the sense of meta-programming. you can produce the strings, lists and maps in every language. i.e., generate)
- language-independent
- values aggregate values
