Data Storage, Security & Integrity

Audit tracking - can we track data that has been deleted?

All deleted objects and data go to the recycle bin, which cannot be emptied by the user.

All edits are recorded as an audit history.

Can I empty the MP-5 recycle bin?

No. Users can not empty the MP-5 recycle bin. This is completely intentional as it provides a record of all data that has entered the system. It is also a requirement of our MCERTS accreditation that users cannot delete data.

Populating the recycle bin has no discernable effect on database efficiency.

Can the detection limit (& lab method) be stored with the result?

Yes. There are many fields built in. These include:

  • Sample type
  • Sample reference
  • Lab Reference
  • Test method
  • Uncertainty
  • Data qualifier
  • Detection limit
  • Data source (lab etc)
  • Analysis date
  • Comments
  • User-defined fields
Can MP-5 handle < (less than) values?

Yes. MP-5 stores both the text of any reading (whether number or text), and the number part of any reading (where there is one) as a number.

Users can define their own 'Less than multiplier' per variable. This enables them to create a numeric value from their < readings of null, zero, 50% of the < reading, 100% of it or any factor in between, according to site or regulatory requirements.

Typically text is used for viewing, and the number field for calculations and summaries in MP-5.

Because of this dual system, a reading of 'DRY' for example is just as relevant as '10'.
