Ukuxhumanisa amatafula ku-Manifold
Ukuxhunyaniswa kwetafula kuyindlela yamathuluzi we-GIS ukuze ukwazi ukuhlobanisa idatha kusuka emithonjeni ehlukahlukene kepha yabelana ngenkambu efanayo. Lokhu yilokhu esikwenze ku-ArcView njenge- "join", iManifold isivumela ukuthi sikwenze kokubili ngamandla, okusho ukuthi, idatha ihlobene kuphela; futhi ngendlela engaxhunywanga, okwenza idatha ifike njengekhophi etafuleni elisetshenziswayo.
Yiziphi izinhlobo zamatafula
I-Manifold ikuvumela ukuthi uphathe izinhlobo ezihlukahlukene zetafula, kufaka phakathi:
- Amatafula avamile. Lezi yizo ezakhiwe ngaphakathi kweManifold, ngenketho "ifayela / dala / itafula"
- Amathebula angenisiwe. Lawa afakwe ngokuphelele, njengamatafula asekelwa yizingxenye ze-Access (CSV, DBF, MDB, XLS, njll.) Noma nge-ADO .NET, ODBC noma izixhumi zomthombo wedatha we-OLE DB.
- Amathebula axhunyiwe. Lokhu kuyafana nokungenisiwe, kepha akufakwa ngaphakathi kwefayela le-.map, kepha kungaba yifayela elihamba phambili elingaphandle futhi "lixhumene" kuphela, lingaba izingxenye ze-Access (CSV, DBF, MDB, XLS, njll. ) noma nge-ADO .NET, ODBC noma OLE DB izixhumi zomthombo wedatha.
- Amathebula ahlanganiswe nomdwebo. Yilezo ezingokwamephu, efana ne-dbf yefomethi, noma amatafula wezimpawu zamafayela e-vector (dgn, dwg, dxf ...)
- Imibuzo Lawa amatafula adalwe kusuka imibuzo yangaphakathi phakathi kwamatafula.
Indlela yokwenza ngayo
- Ithebula elizokhombisa izinkambu ezingeziwe livuliwe futhi inketho ethi "Ithebula / Ubudlelwano" iyatholakala.
- Sikhetha inketho ethi "New Relation".
- Ebhokisini le-Add Relation, khetha elinye ithebula ohlwini olukhonjisiwe Lapha ukhetha ukuthi ufuna ukungenisa noma ukuxhumanisa idatha.
- Ngemuva kwalokho kukhethwa insimu ethebula ngalinye elizosetshenziselwa ukuvumelanisa idatha bese ucindezela KULUNGILE.
Emuva kwibhokisi le- "Yengeza Isihlobo", amakholomu afiswayo kwelinye ithebula ahlolwa ngesheke. Bese ucindezela KULUNGILE.
Umphumela
Amakholamu "abolekwe" kwelinye ithebula azovela anemibala ehlukile yangemuva ukukhombisa ukuthi "axhumekile". Ungenza imisebenzi kuyo njenganoma iyiphi enye ikholomu, ukwenza isibonelo, ukuhlunga, amafomula, noma ukucubungula. Amatafula angaba nobudlelwano obungaphezu kobunye nethebula elingaphezu kwelilodwa.
