Not sure where to start - Editing Access database linked to model

Need some direction here...

I inherited a Microstation 2D model at work. It is littered with pipelines (in the form of lines), all on the appropriate levels (gas, oil, sewer, drain, etc).

There is some intelligence to the lines, with the use of an .mdb Access database.

Once I connect to the .mdb, (and using Review Database Attributes) I click on the line and it tells me what project the pipeline is associated with.

However, most of the lines have no such intelligence. That's fine.

The issue is no one (and I mean NO ONE) here knows how to add intelligence to those lines by editing the database.

I can draw the line on the correct level, but I don't know how to associate the line to the database, to add the project #, line service, line size, etc.

I honestly don't even know where the database is or how to find it.

Can anyone help me get started? How do I locate the database? How do I associate new lines I draw to the database?

Thanks.

Edit: I'm using Microstation Connect Update 14, Ver. 10.314.02.01
