A file-backed hashtable isn't really a DB.
- insanitybit 19d ago
  If someone asked me what a DB is, I'd probably start the conversation with the exact description "a file-backed map, like a hashmap".
- riffraff 19d ago
  Well, dbm (database manager) is basically that and has been called that for almost 50 years
  - otabdeveloper4 19d ago
    dbm isn't a database either, and people who call it that are simply wrong.
    - shakna 18d ago
      So... Databases weren't invented, until after the name was in common use?
- mikedelago 19d ago
  Why not?
  - otabdeveloper4 17d ago
    "Database" implies there's some sort of data aggregation or query primitive under the hood.
    - shakna 16d ago
      In 1971, the Database Task Group, presented the formalisation of a standard to approaches used at the time, CODASYL (1959), in the formation of... COBOL. There is no query primitives in the CODASYL Data Model. Only a Data Manipulation Language. Because "relational" databases didn't really happen until the early '80s - nearly a decade later. (SQL came directly out of work on CODASYL). We had a Database Task Group, long, long, before we had the concept of a query primitive.

  it's not a relational database, but those aren't the only kind.
  - howerj 19d ago
    In fact the name "relational database" implies there are other kinds.

Building dbs is lots of fun. I recently did a few. Some in rust and some in go. And its really interesting.
- ncruces 19d ago
  Agreed. I went the route of building on top of something else. Sill lots of fun. https://github.com/ncruces/go-sqlite3 https://github.com/ncruces/go-sqlite3 And I'm still having fun. https://github.com/ncruces/go-sqlite3/pull/421 https://github.com/ncruces/go-sqlite3/pull/421

No way(hides)

And it's not complete until it can send and receive email.
nunez 19d ago
Yep. I made a simple one in Bash even! (Do not recommend.)
- brabel 19d ago
  You should've used recutils probably :) https://labs.tomasino.org/gnu-recutils/ https://labs.tomasino.org/gnu-recutils/
  - nunez 18d ago
    TIL! Sharding would be so easy! Just run "split" and spread the chunks over a bunch of servers, then run "recutils" with "parallel" to retrieve! Truly webscale.
