Archiving

Archive your PLA 2.0 and PLA 2.1 data within your PLA 3.0 environment.

Statistical changes in PLA 3.0

Some of the concepts of assay documents in PLA have been significantly improved with the introduction of PLA 3.0. The major conceptual changes are:
  • Assays are stored in documents. A single document in PLA 3.0 contains all definitions and raw data. The definitions are no longer distributed over several objects. The Quantitative response assay document within PLA 3.0 is the successor of the Assay, Standard, Preparation, and Control documents known from PLA 2.x.
  • PLA 3.0 stores calculation results within the document. In contrast to PLA 2.x, the results are no longer recreated when a report is created. This allows PLA 3.0 to perform complex calculations with the results of the calculation.

Requirements for the archiving process

Requirements for building a PLA 2.x archive within PLA 3.0 are as follows:
  • The archive needs to include the results as they were calculated within the original PLA 2.x environment.
  • The source environment (PLA version and database) needs to be identifiable.
  • The original PLA reporting (including customer-specific reports) can only be created within the source environment. An assay archive needs to hold all available reports.
  • Audit trail data is database specific. To hold a trace of the raw data, the audit trail from the source environment should be exported and kept available.
  • The archive should contain the assays in PSF format. This PLA 2.x secure file format allows recreating the assay in a PLA 2.x environment.
  • Multiple archives from different PLA 2.x environments should be possible within one single PLA 3.0 database to support data consolidation.

Archiving process

The following figure shows the basic steps of the archiving process:
Figure 1. Basic steps of the archiving process

  1. Extract a project or the whole database from the PLA 2.x source environment into a synchronization folder.

    Note: The synchronization folder can be located on a local file system or a network share. To prevent modifications, the critical data within this folder is protected with a digital signature.

  2. Import the data from the synchronization folder into the PLA 3.0 target environment.
