To be more specific, I created a new feature class in the SDE database, in the same dataset as the buildings. I then loaded the table with data from Excel and created a relationship between the new feature class and the building feature class that has geometry,
Hope that helps.
The tables were a major problem. I spent hours and hours with ESRI because the tables would not replicate to the remote servers. I also did not like the tables for the lack of search functionality. I hear that tables are just like feature classes, yet you can not access them with the Find tool. I am working in a transitory environment with trade people accessing table without the benefit of a designed user interface - everything is temporary, yet we have to keep track of over 100,000 assets including air conditioning units that move daily and are associated with the buildings. So not being able to use Find to search tables, and then identify and link to the building was a major issue.
So back to datasets. Everything i read placed an emphasis on datasets. Are you saying that you find a problem with them for replication? I could easily re-structure without them.
