database - How to link data in an Access table? -


i attempting build database fire extinguisher inspections.

i have 1 table contains of fire extinguishers on site.

id - barcode - maintenance date - hydro date

i have table contain entry when our inspections.

id - barcode - inspection date - inspectors

then each building has it's own table locations.

id - location - lookup extinguisher - data extinguisher table - data inspection table

ie, select extinguisher in building table lookup extinguisher database. want populate rest of fields in building table info each of other two. pulling recent inspection date extinguisher.

i think need query or report. not quite sure.

my data looks this:

buildings table: building names (~100 records)

extinguisher locations: building (linked above) - floor - exact location (description) - current extinguisher (linked below) (~ 1000 records)

extinguishers: size - type - barcode - serial - maintenance date - hydrostatic date (~1200 records)

inspection log: extinguisher (linked above, multiple records per extinguisher may exist) - inspection metrics (rusted? full? maint/hydro date still acceptable?) - inspection date - inspectors

i found nice tutorial on database design, may worth reading. made db design of database like, based on info. not perfect don't know data like, result may little bit this:

enter image description here

if set relations correctly, getting reports 1 suggested should piece of cake.

if building db scratch split extinguisher info separate extinguishertype table , inspectors well.
