Okufanele Ukwazi Ngokukhetha Ukulungiswa Okulungile
I-SQL Server 2008 R2 yiyona ukukhululwa kwamuva kuhlelo lwe-Microsoft lwamabhizinisi ohlangothini lwamafayela wesisekelo sedatha. Njengokuthuthukiswa kwi-platform ye-SQL Server 2008, i-SQL Server 2008 R2 ifika endaweni ephakeme yamanani.
Ake sibheke izinhlelo eziyisikhombisa ezahlukene ze-SQL Server 2008 R2 ongayisebenzisa:
- I-SQL Server 2008 I-R2 Express Edition ithatha isikhundla se-Microsoft Data Engine (MSDE) njengenguqulo yamahhala ye-SQL Server yokuthuthukiswa kwesicelo nokusetshenziswa okulula. Ihlala ikhululekile futhi igcina ukulinganiselwa kwe-MSDE ngokuphathelene nokuxhumana kwamakhasimende nokusebenza. Kuyithuluzi elikhulu lokuthuthukisa nokuhlola izinhlelo zokusebenza nokuqaliswa okuncane kakhulu, kodwa kungakapheli ukuthi ungakwazi ukugijima nayo.
- I-SQL Server 2008 R2 Workgroup ikhokhwa njenge "SQL Server yebhizinisi elincane" futhi inikeza ukuhleleka kokusebenza komuntu we-processor ngayinye ye $ 3,899. (Iphinde itholakale ngaphansi kwelayisensi yomsebenzisi engu-5 ye $ 739). Uhlelo lwe-Workgroup luxhuma kuma-CPU angu-2 nge-3GB ye-RAM futhi luvumela ukusebenza okuningi ongayilindela kusuka kusebenzisweni ehlobene neseva-based. Ihlinzeka ngamakhono okuphindaphinda okulinganiselwe kanye.
- I- SQL Server 2008 R2 Standard Edition isebenza ngokuyinhloko yomzila womkhiqizo wesicelo se-database esiyinkimbinkimbi. Ikwazi ukusingatha ama-CPU angu-4 anenani elingenamkhawulo le-RAM. I-Standard Edition 2005 ingenisa amasevisi wokubumbana nokuhlanganiswa kwedatha. Kuthengiswa ku-$ 7,499 yeprosesa noma i-$ 1,849 kubasebenzisi abangu-5.
- I-SQL Server 2008 Enterprise Edition manje isinganiselwe kunakudala. Ngaphambili yayisekela abacubungula abangenamkhawulo kodwa manje ifakwe kuma-CPU angu-8. Kubuye kubiza kakhulu kunangaphambili ngaphambilini ku-$ 28,749 iprosesa ngayinye noma i-$ 13,969 kubasebenzisi abangu-25.
- Uhlelo olusha lwe- SQL Server 2008 R2 Datacenter Edition lusekela abacubungula abangaba ngu-256 futhi banikeza ukuphela kokuphela kokuphela. I-edatenter edition inikeza ukufinyelela kwamathuluzi wokuphatha amasha we-SQL Server futhi ivumela ukusetshenziswa kwememori engenamkhawulo.
- Olunye uhlelo olusha, i- SQL Server 2008 R2 i-Parallel Data Warehouse Edition inikeza isisombululo esisekelwe kohlelo lokusebenza lwezinhlelo zokusebenza ezigcinwe kakhulu zokugcinwa kwedatha. Isekela ubuciko bokugcina izakhiwo zendawo yedatha nokukhuluma.
- Abathuthukisi abadinga izici ezigcwele ze-SQL Server 2008 R2 Enterprise Edition ukuze basebenzise kwimvelo engekho yokukhiqiza bangathola i- SQL Server 2008 R2 Developer Edition ithuluzi elifanele lomsebenzi. Lo mkhiqizo unomsebenzi ofanayo njengo-Enterprise Edition futhi uhlukile kuphela kwelayisense. (Oh, futhi ngandlela-thile, ishibhile kakhulu ku-$ 50 kuphela ngelayisensi ngayinye!) I-Microsoft iphinde inikeze indlela yokuqondisa ngqo yokuguqula amasiphakeli kanjiniyela kumvume yokukhiqiza
- I-SQL Server 2008 I-R2 Web inguqulo ekhethekile ye-SQL Server ukuze isetshenziswe ezindaweni zokusingatha iwebhu. Njengomagazini we-Standard, awunawo ukulinganiselwa kwinani lememori esetshenzisiwe futhi isekela ukusetshenziswa kwama-CPU angu-4. Amanani wokukhishwa kwewebhu asebenzisa u-$ 15 ngeprosesa ngayinye ngenyanga.
- I-SQL Server 2008 R2 Compact yinguqulo yamahhala ye-SQL Server ukuze isetshenziswe ezindaweni ezihlanganisiwe, njengamadivayisi eselula nezinye izinhlelo zeWindows.
Lokhu kufaka izinketho zokulayisense ezitholakalayo ze-SQL Server 2008 R2. Njengoba uthola, iMicrosoft inikeza amalayisensi ahlukahlukene futhi ukhetha okulungile kwimvelo yakho ingakusindisa izinkulungwane zamaRandi.
