I-PostgreSQL inokutshintsha i-MySQL

Umba entsha ye PC Magazine, ngoku ayisashicilelwa kodwa ukuqwalasela isiphelo oqhelekileyo uwuse kwi Zinio uzisa iingcinga umdla ukuhlafuna phezu futbolera irabha ngoLwesine.

Ndatshitshiswa ngesihloko esithi ngesiSpanish sicacisa Yintoni engalunganga ngeLAMP? ukubhekisela (i-Linux, i-Apache, i-MySQL kunye ne-PHP), iinkqubo ezininzi ezisekelwe kwimpumelelo ye-Intanethi.

postgresql Kule nqaku nguJohn C. Dvorak wenza uhlafuna phakathi kweengozi ezithatha i-MySQL ukufumana yi-SUN / Oracle kunye notshintsho olwenziwa lilayisensi ye-GNU GPL. Phakathi kwemigca, umbhali uqinisekisa ukuba ingxaki yamaphepha-mvume asimahla ayisiyokuziphatha kodwa yeyorhwebo, ecebisa ukuba ingazinzi ngokuhamba kwexesha. Nangona eyingozi, uselungile ukuba siyakhumbula ukuba iinjinjini zethu zedatha ezikhethiweyo (PostGIS), ezilungelelanisa ukusebenza kwimeko-bume ye-GIS, yayikukungaphumeleli kwesisu kangangeminyaka esi-8 njengePostgres kodwa ngoku iyathembisa kakhulu njengePostgreSQL (kodwa kunye nelayisensi ye-BSD).

Abanye abahlobo abatshaya i-geo, ngalo lonke ixesha ndikhankanya i-GPL kubo, bajonge kum njengoko babephambi komfanekiso "wosana olungekazalwa" ngokudana kwabo ukuba yonke into abayenzayo izakuba yindawo yoluntu; kodwa bayayixhasa ilayisensi ye-BSD, abathi "yinkululeko epheleleyo" kuba umbhali womsi unenkululeko engako yokunikezela eluntwini okanye athengise umzamo wakhe kwilayisensi yabucala. Kwabaninzi umba unokuhlekisa, okwangoku kuye kwaliwa amatyala amakhulu kwaye amagqwetha abo kuye kwafuneka bafunde okuninzi malunga netekhnoloji ukuze bakwazi ukufunda nokuqonda kakuhle umngcipheko womxube phakathi kukarhulumente kunye nabucala.

UDvorak uphonsa ezinye izigwebo ezingenampilo eOracle, ngubani onokuthi xa efuna ukubulala ubomi babaninzi esele betyale imali kwiziko ledatha elaziwa kakhulu kwiwebhu. Emva koko uqinisekisa ukuba iPostgreSQL iya kuthatha indawo kwaye iphepha-mvume lakhe le-BSD limthanda naphina apho sifuna ukumbona khona. Ngaphandle kokwenza impazamo encinci (uyibiza ngokuba yiPostgrSQL), kubonakala ngathi inomdla kum, mhlawumbi iyakusinceda kwicala lesithuba emva komdla wethu kwiPostGIS esele wahamba kakuhle.

  1. Ndivuma kakhulu, nangona imbambano inengxabano kumbono woshishino kunye nomthetho

  2. Into ye-BSD kunye nenkululeko epheleleyo… kulungile, bekuhlala kubonakala ngathi nguMartian kum ukuphikisa ukuba i-GPL iyayithatha inkululeko. Isithintelo ekuphela kwaso esibekwa yiGPL sithintela abantu ekumiseleni ezinye izithintelo.
