Uyithutha kanjani isizindalwazi sisuka ku-MS Access siye ku-SQL Server isinyathelo ngesinyathelo

Microsoft Finyelela bekuyithuluzi elidumile lokuphatha yolwazi, kodwa njengoba amabhizinisi ekhula, ukulinganiselwa kwawo kungase kubonakale. Ukuze uthole isizindalwazi esikhulu nesifuna kakhulu, Thuthela ku-SQL Server Kuyisixazululo esisebenzayo, esinikeza ukusebenza okungcono, ukuphepha y ukukhubazeka.

Uma ucabangela lolu shintsho, lo mhlahlandlela uzokusiza uqonde isinyathelo ngasinye senqubo, kusukela ku- ukuhlola kokuqala kuze kube nokwenza kahle kusuka kusizindalwazi esithuthiwe. Uzofunda ngamathuluzi alungile, izinkinga ezingase ziphakame, kanye nendlela yokuqinisekisa ukuthuthwa okuphumelelayo ngaphandle kokulahlekelwa idatha.

Kungani uthutha isizindalwazi sisuka ku-MS Access siye ku-SQL Server?

Uma inkampani iqala ukuphatha idatha enkulu noma abasebenzisi abaningi ngesikhathi esisodwa, Ukufinyelela kungase kunganele. Nazi izizathu ezibalulekile zokufuduka:

• Umthamo omkhulu we isitoreji: Ukufinyelela kunomkhawulo ongu-2 GB, kuyilapho i-SQL Server ikuvumela ukuthi ugcine kufika ku-524 Petabytes.
• Ukusebenza kangcono: Iseva ye-SQL iphatha imibuzo emikhulu ngokuyimpumelelo ngokuthuthukisa isivinini sokufinyelela idatha.
• Ukuphepha okuthuthukisiwe: Ikuvumela ukuthi uphathe izimvume zomsebenzisi okuthuthukisiwe nokubethela, okunciphisa ubungozi bokufinyelela okungagunyaziwe.
• Inombolo ephezulu yabasebenzisi ngesikhathi esisodwaNakuba i-Access inomkhawulo wabasebenzisi abangu-255 ngesikhathi esisodwa, i-SQL Server ingakwazi ukuphatha inombolo engenamkhawulo.

Ukulungiselela ngaphambi kokufuduka

Ngaphambi kokuqala inqubo, kubalulekile ukuthatha izinyathelo ezithile zokugwema izinkinga. Landela lezi zinyathelo zangaphambilini ukuqinisekisa uguquko olushelelayo:

• Yenza isipele qedela Ukufinyelela kusizindalwazi.
• Hlola isikhala sediski ukuqinisekisa ukuthi i-SQL Server inomthamo owanele wokugcina idatha.
• hlola izimvume: Qiniseka ukuthi unezimvume ezifanele zokufinyelela nokuguqula kokubili Ukufinyelela kanye Neseva ye-SQL.
• Lungiselela amatafula: Engeza okhiye abayinhloko futhi uqinisekise ukuthi banjalo ubudlelwano phakathi kwamatafula vumelana.

Isinyathelo ngesinyathelo: Ungathutha Kanjani Ukufinyelela Kuseva ye-SQL

1. Sebenzisa i-Microsoft SQL Server Migration Assistant (SSMA)

I-SSMA ingelinye lamathuluzi asetshenziswa kakhulu ekuthutheleni imininingwane yolwazi iye kuseva ye-SQL. Lezi yizinyathelo eziyisisekelo:

• Landa futhi ufake i-SSMA esebenzisana ne-Access.
• Vula i-SSMA bese udala iphrojekthi entsha.
• Xhuma kusizindalwazi sokufinyelela ofuna ukusithutha.
• Ihlaziya ukwakheka kwesizindalwazi bese ikhiqiza umbiko wokuhambisana.
• Xhuma ku-SQL Server futhi uguqule i-Access schema.
• Hambisa idatha futhi ulungise amapharamitha njengoba kudingeka.

2. Guqula futhi ubuyekeze izinto

Iseva ye-SQL kanye Nokufinyelela kusingatha izinto ezithile ngendlela ehlukile. Ezinye izinto zingase zidinge ukulungiswa mathupha:

• Amathebula nezikimu kufanele zibuyekezwe ukuze kuqinisekiswe ukuthi zidluliselwe ngendlela efanele.
• Eminye imibuzo yokufinyelela ingase idinge izinguquko ku-T-SQL.
• Okhiye bakwamanye amazwe kanye nobudlelwano kufanele buqinisekiswe kusizindalwazi esisha.

3. Xhumanisa amathebula kokuthi Ukufinyelela

Uma ufuna ukuqhubeka usebenzisa Ukufinyelela njengesixhumi esibonakalayo ngenkathi ugcina idatha Kuseva ye-SQL, ungaxhuma amathebula kokuthi Ukufinyelela. Le nqubo iwusizo ekuguqukeni kancane kancane lapho abasebenzi beqhubeka nokusebenzisa Ukufinyelela ngaphandle kwezinguquko ezinqala.

4. Ukuhlolwa nokuqinisekisa

Uma ukuthutha sekuqediwe, kubalulekile ukuqinisekisa ukuthi yonke into isebenza kahle:

• Isebenzisa imibuzo yokuqinisekisa ukuze kuqinisekiswe ukuthi idatha idluliswe ngendlela efanele.
• Yenza izivivinyo zokusebenza ukuze uqhathanise isivinini sombuzo phakathi kokufinyelela kanye neseva ye-SQL.
• Qinisekisa ukuthi abasebenzisi bangakwazi ukufinyelela kalula kusizindalwazi.

Ukuthuthukisa i-SQL Server ngemva kokuthutha

Ukuqinisekisa ukuthi isizindalwazi sakho sisebenza kahle, cabanga ukwenza izinguquko ezilandelayo:

• Izinkomba kanye nokwenza kahle kwemibuzo: Sebenzisa izinkomba kumathebula amakhulu ukuze uthuthukise ukusebenza.
• Ukuphepha nezimvume: Lungiselela izindima ezifanele nezimvume ukuze uvimbele ukufinyelela okungagunyaziwe.
• Isondlo kanye nezipele: Sungula izinhlelo zokulungisa ukuze wenze izipele ngezikhathi ezithile.

Njengoba izinkampani zikhula, Ukufuduka kusuka ku-MS Access kuya ku-SQL Server kuba isidingo ukuthuthukisa ukusebenza kahle nokuphepha kwedatha. Ngokulandela lo mhlahlandlela, uzokwazi ukuqedela inqubo ngesinyathelo ngesinyathelo ngaphandle kwezinkinga, uqinisekisa ukuguqulwa okuphumelelayo ngaphandle kokulahlekelwa kolwazi.
