UPDATE: Ovaj MSDN objavljivanja ima neke zanimljive primjedbe iz JXJ na temelju njegove, uglavnom negativno, Iskustva ide dolje ovaj put: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2623565&SiteID=1

We have a business scenario where we need to link two documents libraries via a common "document ID" polje.

We often use a lookup column to implements links like this. There are several drawbacks to lookup columns, od kojih su tri:

  1. Only one column from the lookup lookup library can be linked.
  2. Performanse: The source library could contain hundreds of entries. That’s too many entries in the lookup.
  3. Traži: There is no integrated search. I don’t mean in the MOSS sense of search, ali ne postoji način da se traži / filtrirati po više stupaca iz knjižnice izvorni dokument i pronađite link koji želite.

Potpomognuti BDC, we can use a "business data" column type and it provides a superior search and even allows multiple columns of data to appear in list views.

Ja sam imao neke preliminarne uspjeh s ovom pristupu, a planiramo pisati više o tome.

Ako ste radili ovaj kut prije i imate bilo kakve komentare, molimo udjela!

Jedna misao o „BDC Čini Održive zamjena za lookups”

  1. No name
    The two biggest downsides for me:
    1) A BDC column cannot be part of a Content Type, at least as far as I know. (Apparently this was allowed in the MOSS beta and was taken out). I’ve tried using a Content Type for a list and then just adding the BDC column directly to the list, but then I ran into problems setting the order of the fields in the list (na primjer, the order they appear when adding a new item or editing an item).
    2) I haven’t seen a way to make the BDC picker simply display a list of items and allow one to be selected. I always have to enter some criteria and click the search button. If the list isn’t that long, I just want it to display all values – or if I don’t know what I’m looking for, I’d like to leave the criteria blank and click the search button and find everything. It won’t allow that (unless I am wrong and I don’t have my BDC app definition set up correctly).
