Interested in integration with 1C and webpart development.

1. The SharePoint user profile displayed information from 1c (number of unused vacation days)
2. It is necessary to implement equipment accounting for the IT service
3. The web part of the telephone directory with synchronization via AD
Interested in where to start studying in order to it was possible to somehow start developing a BI system on SharePoint.

Answer 1

The task is not very difficult if the login or something that identifies the user is stored in 1C. Make a web service on the 1C side, and on the SP side make a TimerJob that processes User Profiles from the User Profile Service according to the schedule.

Answer 2

Interested in integration with 1C and webpart development. - The word integration is not clear, what are you going to integrate into?
2. It is necessary to implement accounting of equipment for the IT service - try to put Everest data on the portal, and then "keep" the history
3. web part phone directory with synchronization via AD - there is synchronization with AD, why make a separate web part?
1. The SharePoint user profile displayed information from 1c (number of unused vacation days) - here the most important thing is to decide on the user ID, 1C in the form of a personnel number, then transfer this number to Sharepoint in 1C, do Rest with this data, or from 1s you upload XML once a week, and put it on the portal, it seems to me that there will be less trouble with XML.

Answer 3

You need to start by forgetting the word Sharepoint, if it's not too late...
