Yintoni Okumele Uyazi Ngokukhetha Ulungelelwano Oluchanekileyo
I-SQL Server 2008 R2 yiyo yakhululwa ngokutsha kwiinkcukacha ze-Microsoft. Njengokuphucula kwi-platform yeSQL Server 2008, iSQL Server 2008 R2 ifika kwindawo ephezulu.
Makhe sijonge iinguqu ezisixhenxe zeSQL Server 2008 R2 ongayisebenzisa:
- I-SQL Server 2008 I-R2 Express Edition ithatha indawo ye-Microsoft Data Engine (MSDE) njengenguqulo yamahhala yeSquL Server malunga nokuphuhliswa kwesicelo kunye nokusetyenziswa okulula. Ihlala ikhululekile kwaye igcina ukulinganiselwa kwe-MSDE ngokumalunga nokuxhunywa kwabathengi kunye nokusebenza. Isixhobo esikhulu sokuphuhlisa kunye nokuvavanya izicelo kunye nokuphunyezwa okuncinci kakhulu, kodwa ke malunga nokuba unako ukuhamba nayo.
- I-SQL Server 2008 I-Workgroup ibhalwa njenge "SQL Server" encinci kwaye inika umgangatho osebenzayo wokusebenza kwintengiso nganye yee-3,899. (Ikwafumaneka kwakhona phantsi kwelayisensi yomsebenzisi-5 ye-$ 739). Inkqubela ye-Workgroup ixhuma kwi-CPU ye-3GB ye-RAM kwaye ivumela ubuninzi bomsebenzi onokuyilindela kwi-database-based based relation database. Inika amandla okuphindaphinda ngokukhawuleza .
- I- SQL Server 2008 ye-R2 Standard Edition isebenza ngokuyinhloko yomgca womkhiqizo kwizicelo ezinzulu ze-database. Iyakwazi ukufikelela kuma-CPU angama-4 enexabiso elingenamkhawulo le-RAM. I-Standard Edition 2005 izisa iinkonzo zemiyalezo yokudibanisa kunye nokudibanisa. Ixabiso lentengo kwi-$ 7,499 yeprojekthi okanye i-$ 1,849 yabasebenzisi aba-5.
- I-SQL Server 2008 I-Enterprise Edition ngoku iyancinci kunokuba idlulileyo. Kwangaphambili yayisekela abaprojekthi abangenamkhawulo kodwa ngoku ikhutshwe kuma-CPU ayi-8. Kwakhona kubiza ngakumbi kunokuba bekude kwi-28,749 yeprojekthi okanye i-$ 13,969 yabasebenzisi abangama-25.
- I- SQL Server 2008 R2 iDatacenter Edition isekela kwiiprojekti ezinengqiqo ezingama-256 kwaye inika ukuphela kokuphela kokuphela. Ipapasho leDatacenter linikeza ukufikelela kwiinkqubo ezintsha zokulawula i-SQL Server kwaye ivumela ukusetyenziswa kwememori engenamkhawulo.
- Olunye uhlobo olutsha, iSQL Server 2008 R2 efana nedatha yoLondolozo lweeNdawo zoLondolozo lunikeza isisombululo esisetyenzisweni-mveliso sokusetyenziswa kwezixhobo zokugcina idatha. Ixhasa ulwabiwo-mbhalo lwendawo yolondolozo lwendawo yolwazi oluphambili.
- Abathuthuli abafuna iimpawu ezipheleleyo ze-SQL Server 2008 R2 Enterprise Edition ukuze basebenzise kwimimandla engekho imveliso bangayifumana i- SQL Server 2008 R2 Developer Edition ithuluzi elifanelekileyo lomsebenzi. Le mveliso inokusebenza ngokufanayo kunye no-Edited Enterprise Edition kwaye ihluke kuphela kwilayisenisi. (Hayi, kwaye ngendleleni, ixabiso elincinci kuma-50 kuphela ngelayisenisi!) UMicrosoft unikezela indlela yokuhlaziya ngokuthe ngqo yokuguqula iiseva zonjiniyela ukuya kwilayisenisi yokuvelisa
- I-SQL Server 2008 I-Web yeW2 iyinqobo ekhethekileyo yeSQL Server ukusetyenziswa kwiindawo zokusingatha kwiwebhu. Njengomxholo we-Standard, akukho mingcele kwimali yememori esetyenzisiweyo kwaye isekela ukusetyenziswa kwama-CPU angama-4. Ixabiso lomshicileli wewebhu luqhuba i-$ 15 nganye ngeprojekthi nganye ngenyanga.
- I-SQL Server 2008 R2 Compact yinguqulelo yamahhala yeServy Server ukuze isebenze kwiindawo ezifakwe kwi-intanethi, njengezixhobo zeselula nezinye iifenisi zeWindows.
Oko kubonisa ukukhethwa kweelayisenisi ezikhoyo kwi-SQL Server 2008 R2. Njengoko ufumene, iMicrosoft inikezela ngeentlobo ezininzi zeelayisenisi kwaye ukhetha oluchanekileyo kwimeko yakho ingakugcina amawaka eedola.
