Dolt-projektet udvikler en database, der kombinerer SQL-support med dataversionskontrol i stil med Git. Dolt g\u00f8r det muligt at klone tabeller, oprette forgreninger og udf\u00f8re sammenfletninger af tabeller samt udf\u00f8re push og pull-aktioner ligesom i et Git-repositorium. Samtidig underst\u00f8tter databasen SQL-foresp\u00f8rgsler og er kompatibel med MySQL p\u00e5 klientsidens niveau. Projektets kode er skrevet i Go og distribueres under Apache 2.0-licensen. <\/p>\n

Mulighederne for versionering af data i databasen g\u00f8r det muligt at spore oprindelsen af data \u2013 bindingen til commits giver mulighed for at fasts\u00e6tte tilstanden, s\u00e5 identiske resultater kan reproduceres p\u00e5 andre systemer uanset den aktuelle tilstand. Derudover kan brugere navigere gennem historien, spore \u00e6ndringer i tabellerne ved hj\u00e6lp af SQL uden behov for at sammenligne backups, udf\u00f8re revisions\u00e6ndringer samt danne foresp\u00f8rgsler, der d\u00e6kker data p\u00e5 et bestemt tidspunkt.

\"Dolt-database,<\/center> <\/p>\n

DBMS tilbyder to driftsmodi \u2013 Offline og Online. Efter overgangen til offline bliver indholdet af databasen tilg\u00e6ngeligt som et repository, som man kan udf\u00f8re handlinger med ved hj\u00e6lp af et git-lignende kommandolinjev\u00e6rkt\u00f8j. Arbejdet ligner i h\u00f8j grad git og adskiller sig hovedsageligt ved, at \u00e6ndringerne ikke spores for filer, men for indholdet af tabellerne. Gennem det tilbudte CLI-interface kan man importere data fra filer i CSV- eller JSON-format, tilf\u00f8je commits med \u00e6ndringer, vise forskelle mellem versioner, oprette branches, s\u00e6tte tags, udf\u00f8re push-foresp\u00f8rgsler til eksterne servere og udf\u00f8re sammenfletninger af \u00e6ndringer foresl\u00e5et af andre deltagere. <\/p>\n

Hvis \u00f8nskes, kan data placeres i kataloget DoltHub, som kan betragtes som en tilsvarende platform til GitHub for datahosting og samarbejde om data. Brugere kan oprette forks af datalag, foresl\u00e5 deres \u00e6ndringer og lave fusioner med deres data. For eksempel kan man i DoltHub finde forskellige databaser med statistik om coronavirus, samlinger af annoterede data til maskinl\u00e6ringssystemer, sproglige leksikalske databaser, samlinger af billeder, s\u00e6t til objektklassificering og information om tilknytning. IP-adresser<\/a>. <\/p>\n

I «online» tilstand startes Dolt SQL Server, som g\u00f8r det muligt at manipulere data ved hj\u00e6lp af SQL. Det tilbudte interface ligner MySQL og kan anvendes gennem kompatible MySQL-klienter eller ved hj\u00e6lp af CLI-interface. Dolt fungerer mere som et v\u00e6rkt\u00f8j til datamanipulation end som et foresp\u00f8rgselssystem. For eksempel kan SQL-serveren som standard kun h\u00e5ndtere \u00e9n aktiv brugerforbindelse til repository'et, der er placeret i den aktuelle mappe (denne adf\u00e6rd kan \u00e6ndres gennem indstillingerne). server<\/a> til tilstand kun for l\u00e6sning. Mange handlinger relateret til versionskontrol kan ogs\u00e5 udf\u00f8res via SQL, s\u00e5som at lave commits eller skifte mellem grene.
