Finyelela Kulwazi Olugciniwe: Igayidi Yokuqala Yabaqalayo

Isingeniso kusizindalwazi esinokufinyelela

Imininingo egciniwe isenhliziyweni yokuphathwa kolwazi ezweni lanamuhla ledijithali. I-Microsoft Access, ithuluzi elinamandla neliguquguqukayo, isiphenduke isango labaqalayo abaningi emhlabeni othakazelisayo wolwazi. Kulo mhlahlandlela obanzi, sizofaka zonke izinto ezibalulekile ukuze sikusize ube yingcweti yolwazi Lokufinyelela futhi sibeke isisekelo somsebenzi wakho wokuphatha idatha.

Ukufinyelela kuhlanganisa ubulula besixhumi esibonakalayo esibonakalayo namandla esistimu yokuphathwa kwesizindalwazi esihlobene. Le nhlanganisela ikwenza kube ukukhetha okuhle kulabo abafuna ukuqalisa emhlabeni wolwazi ngaphandle kokuthi bangene baqonde ezilimini zokuhlela eziyinkimbinkimbi njenge-SQL.

Kuso sonke lesi sihloko, sizohlola yonke into kusukela emicabangweni eyisisekelo kuye kumasu athuthukile, sikunikeza ukuqonda okuqinile kokuthi ungakha kanjani, uphathe, futhi ulungiselele imininingwane yolwazi ngokuFinyelela. Kungakhathaliseki ukuthi ubheke ukuhlela ulwazi lomuntu siqu noma ukuthuthukisa izixazululo zebhizinisi, lo mhlahlandlela uzokuhlomisa ngolwazi oludingayo ukuze uthole okuningi kuleli thuluzi.

I-Microsoft Access Fundamentals

I-Microsoft Access iwuhlelo lokuphatha isizindalwazi esihlobene esiyingxenye ye-Microsoft Office suite. I-interface yayo enembile nokuhlanganiswa namanye amathuluzi e-Office kuyenza ibe ukukhetha okudumile kubo bobabili abasebenzisi abasaqalayo nabachwepheshile.

Iyini isizinda sedatha esihlobene?

Isizindalwazi esihlobene siwuhlobo lwesizindalwazi esihlela ulwazi lube ngamathebula axhumene. Ithebula ngalinye limelela into ethile (njengamakhasimende, imikhiqizo, noma ama-oda), futhi ubudlelwano phakathi kwala mathebula bukuvumela ukuthi udale ukuxhumana okunengqondo phakathi kwedatha. Le modeli yesizindalwazi iyisisekelo sokuqonda ukuthi i-Access isebenza kanjani.

Izingxenye eziyinhloko zokufinyelela

  1. Amathebula: Ziyisisekelo sanoma iyiphi isizindalwazi ekufinyeleleni. Yilapho ulwazi lugcinwa khona emigqeni (amarekhodi) kanye namakholomu (izinkambu).
  2. Imibuzo: Zikuvumela ukuthi ubuyise, uhlunge futhi uhlaziye idatha kuthebula elilodwa noma amaningi. Imibuzo iyingxenye ebalulekile yokusebenza nesizindalwazi se-SQL ngaphakathi kokufinyelela.
  3. Amafomu: Benza lula ukufakwa kwedatha nokuboniswa ngendlela esebenziseka kalula kunamathebula aluhlaza.
  4. Imibiko: Avumela idatha ukuthi yethulwe ngendlela ehlelekile nebukekayo ukuze ihlaziywe noma iphrintwe.
  5. I-VBA Macros namamojula: Bahlinzeka ngokuzenzakalelayo nokusebenza okuthuthukile kubasebenzisi abanolwazi oluthe xaxa.

Izinzuzo zokusebenzisa i-Access for database

  • Ukusetshenziswa kalula: Isixhumi esibonakalayo sayo sikuvumela ukuthi udale futhi uphathe imininingwane yolwazi ngaphandle kwesidingo solwazi olujulile lokuhlela.
  • Ukuhlanganiswa Kwehhovisi: Isebenza kahle ne-Excel, i-Word nezinye izinhlelo ze-Microsoft.
  • Ukwehluka: Ilungele amaphrojekthi amancane naphakathi nendawo, anethuba lokuthuthela ezinhlelweni eziqinile njenge-SQL Server.
  • Ukwenza kube ngokwakho: Inikeza izinga eliphezulu lokuguquguquka ukuze uvumelane nedathabheyisi nezidingo ezithile.

Ukuqalisa nge-Access

Ukuqala, kubalulekile ukuzijwayeza isixhumi esibonakalayo sokufinyelela. Lapho uvula uhlelo lokusebenza, uzonikezwa izinketho zokwenza isizindalwazi esisha noma uvule esivele sikhona. Ukuhlola izifanekiso ezichazwe ngaphambilini kungaba yindlela enhle yokuqonda ukwakheka kwesizindalwazi esiklanywe kahle.

Uma usudale isizindalwazi sakho sokuqala, thatha isikhathi sokuhlola iribhoni kanye nemibono ehlukene etholakalayo. Ukubuka kwesakhiwo sethebula, isibonelo, kuzokuvumela ukuthi uchaze izinkambu nezinhlobo zedatha, kuyilapho ukubuka kwedatha kuzokubonisa amarekhodi ngefomethi efana ne-spreadsheet.

Khumbula ukuthi ukuzijwayeza kuyisihluthulelo. Ungesabi ukuhlola izakhiwo nemisebenzi ehlukene. Njengoba uqhubeka ngalo mhlahlandlela, uzokwakha isisekelo esiqinile sokudala imininingo egciniwe yokufinyelela eyinkimbinkimbi futhi ephumelelayo.

Ukuklama amatafula nobudlelwano

Ukuklama amathebula nokudala ubudlelwano kubalulekile ekwakheni isizindalwazi esisebenza kahle nesisebenzayo ekufinyeleleni. Lesi sigaba sibeka isisekelo sawo wonke umsebenzi olandelayo, ngakho-ke kubalulekile ukunikela isikhathi esidingekayo kanye nokunaka kuso.

Ukudala amathebula asebenzayo

Lapho udala amathebula Ekufinyeleleni, kubalulekile ukulandela izinqubo ezithile ezinhle:

  1. Ukumisa: Hlukanisa ulwazi kumathebula anengqondo ukuze ugweme ukuphindaphinda kwedatha. Isibonelo, esikhundleni sokuba netafula elilodwa elinalo lonke ulwazi lwekhasimende noku-oda, dala amathebula ahlukene amakhasimende nama-oda.
  2. Ukukhetha izinhlobo zedatha: Khetha uhlobo lwedatha olufanele lwenkambu ngayinye (umbhalo, inombolo, idethi, njll.). Lokhu akugcini nje ngokusindisa isikhala, kodwa futhi kuthuthukisa ubuqotho bedatha.
  3. Okhiye abayinhloko: Ithebula ngalinye kufanele libe nokhiye oyinhloko oyingqayizivele okhomba irekhodi ngalinye. Ukufinyelela kungenza ngokuzenzakalelayo inkambu ethi "ID" yenombolo ezenzakalelayo yale njongo.
  4. Izinkambu ezibaliwe: Sebenzisa izinkambu ezibaliwe ukuze uthole ulwazi olungatholwa kwezinye izinkambu, kunokulugcina ngokuqondile.

Ukusungula ubudlelwano

Ubudlelwano buyinhliziyo yemodeli yesizindalwazi esihlobene. Ekufinyeleleni, ungakha izinhlobo ezimbalwa zobudlelwano:

  • Kunye ngakunye: Irekhodi ngalinye kuThebula A lihlobene nerekhodi elilodwa kuThebula B.
  • Omunye kwabaningi: Irekhodi elikuThebula A lingahlotshaniswa namarekhodi amaningana kuThebula B.
  • Abaningi kwabaningi: Amarekhodi amaningi kuThebula A angahlotshaniswa namarekhodi amaningi kuThebula B (ngokuvamile asetshenziswa ngetafula lokuhlanganisa).

Ukwakha ubudlelwano:

  1. Yiya kuthebhu ethi “Amathuluzi Esizindalwazi” bese ukhetha “Ubudlelwano.”
  2. Hudula izinkambu ezihlobene phakathi kwamathebula ukuze udale uxhumano.
  3. Ichaza ubuqotho obuyinkomba ukuze kugcinwe ukuvumelana kwedatha.

Ubuqotho obuyisithenjwa

Ubuqotho bereferensi bubalulekile ekugcineni ukuhambisana kwedatha kusizindalwazi sakho. Uma uyivula:

  • Ivimbela amarekhodi akhonjiswa ngamanye amathebula ukuthi asuswe.
  • Iqinisekisa ukuthi idatha ayikwazi ukufakwa kuthebula elihlobene uma irekhodi elihambisanayo lingekho kuthebula lomzali.
  Indlela yokweqa isizindalwazi sereferensi ku-Excel kahle futhi kalula

Isibonelo esisebenzayo sesizindalwazi esinokufinyelela

Ake sicabange ngesizindalwazi sesitolo esiku-inthanethi. Singaba namathebula alandelayo:

  1. Amakhasimende: ID_Client (ukhiye oyinhloko), Igama, I-imeyili, Ikheli
  2. Imikhiqizo: Product_ID (ukhiye oyinhloko), Product_Name, Price, Stock
  3. Ama-oda: I-oda_ID (ukhiye oyinhloko), Customer_ID (ukhiye wangaphandle), Order_Date
  4. Oda_Imininingwane: I-Detail_ID (ukhiye oyinhloko), i-Order_ID (ukhiye wangaphandle), Product_ID (ukhiye wangaphandle), Ubuningi

Kule modeli, sizosungula ubudlelwano phakathi kwamakhasimende nama-oda, naphakathi kwama-oda kanye ne-Order_Details. Ithebula le-Order_Details lisebenza njengethebula lokuhlanganisa lobudlelwano phakathi kwama-oda nemikhiqizo.

Uma uklama amathebula akho nobudlelwano, hlala ucabanga ukuthi idatha ihlobana kanjani emhlabeni wangempela. Idizayini egciniwe egciniwe ikhombisa indlela yokucabanga yesistimu oyimodelisayo, yenza kube lula ukubuza imibuzo nokunakekela isikhathi eside.

Khumbula ukuthi ukwakheka kwesizindalwazi kuyinqubo ephindaphindayo. Ungesabi ukwenza izinguquko njengoba uqonda kangcono izidingo zakho zedatha. Ngokuzijwayeza nolwazi, uzothuthukisa umuzwa wemvelo wokudala izakhiwo zesizindalwazi sokuFinyelela ezinamandla nezisebenza kahle.

Ukubika ngokwezifiso kanye nokuhlaziywa kwedatha kuyizingxenye ezibalulekile zokusetshenziswa kwesizindalwazi esithuthukisiwe noFinyelela. Ngokufunda lawa maqhinga, uzokwazi ukukhipha imininingwane ebalulekile kudatha yakho futhi uyethule ngempumelelo kuzithameli ezahlukene. Ngaso sonke isikhathi khumbula ukwenza imibiko yakho ifanele izidingo ezithile zezethameli zakho futhi ugcine ibhalansi phakathi kokuqondanisa kolwazi nokucaca kokwethulwa.

I-Automation enama-macros kanye ne-VBA

Ukuzenzakalela kuyisihluthulelo sokuthuthukisa ukusebenza kahle nokusebenza kwezizindalwazi zakho zokufinyelela. Kokubili ama-macros kanye ne-Visual Basic for Applications (VBA) ahlinzeka ngamathuluzi anamandla okwenza imisebenzi ephindaphindwayo ngokuzenzakalelayo, ukusebenzisa ingqondo yebhizinisi eyinkimbinkimbi, nokudala izixazululo ngokwezifiso.

Isingeniso kumamakhro ekufinyeleleni

Ama-Macro ayizinhlu zezenzo ongazenza ngaphandle kolwazi lokuhlela . Alungele imisebenzi elula nephindaphindwayo.

Izinzuzo zama-macros:

  • Kulula ukudala nokuguqula
  • Alukho ulwazi lokuhlela oludingekayo
  • Iphephile futhi kulula ukuyisusa

Isibonelo se-macro elula yokuvula ifomu:

  1. Dala i-macro entsha
  2. Engeza isenzo se-"OpenForm".
  3. Khetha ifomu ofuna ukulivula
  4. Londoloza imakhro
  Izibonelo zemibuzo yamathebula amaningi e-MySQL

Amamakhro Athuthukile

Amamakhro angaba yinkimbinkimbi kakhulu:

  1. Amamakhro anemibandela: Benza izenzo ezisekelwe ezimweni.
  2. Amamakhro edatha: Benza imisebenzi kudatha ekumathebula.
  3. I-interface yomsebenzisi Macros: Benza okuhlangenwe nakho komsebenzisi kube ngokwakho.

  • Ikhono lokudala imisebenzi yangokwezifiso

Ukuze uqalise nge-VBA:

  1. Vula i-Visual Basic Editor (Alt + F11)
  2. Faka imojuli entsha noma ifomu
  3. Bhala ikhodi yakho ye-VBA

I-VBA Basics

Ezinye izakhiwo eziyisisekelo ku-VBA:

  1. Okuguquguqukayo nezinhlobo zedatha:
Dim nombreCliente As String
Dim edad As Integer
Dim precioTotal As Currency
  1. Izakhiwo zokulawula:
If edad >= 18 Then
MsgBox "Eres mayor de edad"
Else
MsgBox "Eres menor de edad"
End IfUkuze i = 1 Kuya 10
Ukuhlukumeza.Phrinta i
Okulandelayo i
  1. Imisebenzi kanye subroutines:
Function CalcularDescuento(precio As Currency) As Currency
If precio > 100 Then
CalcularDescuento = precio * 0.1
Else
CalcularDescuento = 0
End If
End FunctionOkungaphansi UpdateInventory()
' Ikhodi yokuvuselela i-inventory

  1. Ukubuyekezwa okukhulu kwerekhodi:
Sub ActualizarPrecios()
Dim db As Database
Dim rs As Recordset

Misa db = YamanjeDb
Misa rs = db.I-OpenRecordset("Imikhiqizo")Yenza Ngenkathi Not rs.EOF
rs.Hlela
rs!Intengo = rs!Intengo * 1.05 ' Nyusa intengo ngo-5%
rs.Update
rs.Hambisa Okulandelayo
