Pješčanik, tempo i certifikat

Što još ima na stanici

Signal iz mrtvog sektora stabilan je: QUERY je učvrstio kanal i podigao kopiju baze Kotomarketa u izoliranom krugu stanice. Sada imaš sve za dulji rad — preostaje ti obići odjeljke.

• Vježbalište — zadaci idu od jednostavnih do zahtjevnih; na njima ono što si shvatio pretvaraš u naviku.
• Pješčanik — izolirana kopija arhiva: original je nedodirljiv, a ovdje je sve dopušteno — možeš slobodno pisati SQL, provjeravati pretpostavke i promatrati podatke Kotomarketa iz raznih kutova.
• Napredak i Power — za lekcije i zadatke dobivaš bodove (Power), raste ti rang i gradiš niz dana bez prekida (streak).
• Ispiti i certifikat — kad završiš tečaj, možeš položiti ispit i dobiti certifikat na svoje ime s QR provjerom: svoju arhivističku licencu.

Kreneš li redom, složit će ti se cjelovita karta SQL-a: od prvog čitanja tablice do upita o kojima možeš mirno razgovarati na razgovoru za posao — ili ih iznijeti pred Vijeće Akademije.

QUERY: Pješčanik je moj omiljeni odjeljak. Što god u njemu slomiš, original neće stradati. Provjereno. Osobno. Dvaput.

What else is on the station

The signal from the dead sector holds steady: QUERY has locked the channel and spun up a copy of the "Kotomarket" database in an isolated circuit aboard the station. Now you have everything you need for the long haul — all that’s left is to walk the bays.

• Trainer — tasks run from easy to combat-grade; this is where you turn a topic you understand into a habit.
• Sandbox — an isolated copy of the archive: the original stays untouchable, and here anything goes — write SQL freely, test your hunches and look at the "Kotomarket" data from every angle.
• Progress and Power — lessons and tasks earn you points (Power), your rank grows, and a run of no-miss days (a streak) builds up.
• Exams and certificate — once you finish the course you can sit an exam and get a named certificate with a QR check: your archivist’s license.

Go through it in order and a whole map of SQL takes shape — from your first read of a table to queries you can comfortably talk through in an interview, or lay before the Academy Council.

QUERY: The sandbox is my favorite bay. Whatever you break in there, the original won’t suffer. Confirmed. By me. Twice.

QUERY dims the extra panels. One stays lit — a dark schema where you can just make out the five silhouettes of the "Kotomarket" tables.

QUERY: The signature "K." can wait. Before you read someone else’s memory, cadet, understand how it’s put together. Next watch — the map of the archive.
