Comments

Comments:

The linkage key is designed to make it possible to count number of clients and services they received, without counting the same client more than once. It can also be used for linking to other related data collections. It is for statistical linkage purposes only, not for case management or the tracking of individual persons. This may be done using a range of identifiers and/or keys.
