Resumo
Introduction: OpenEHR is a standardization of Health Information Systems (HIS) that is mainly concerned
with the exchange of Electronic Health Records (EHR). One of the major obstacles to the adoption of
openEHR is the lack of database persistence specifications. Objective: The aim of this work is the mapping
of storage structures from the Archetype Definition Language (ADL) specifications which describe clinical
knowledge structure. Method: This research initially makes a systematic mapping about persistence
structures that are derived directly from ADL specifications, i.e. without dependences from the Reference
Model (RM) of openEHR. A new persistence strategy is proposed and compared with ones found in the
literature. Results: Assumptions, criteria and rules were used to present the proposed approach. Its
evaluation considered quantitative aspects of persistence structures. Conclusion: The evaluation revealed
some advantages of proposed approach, such as: reductions of reference attributes (referential integrity) and
redundancy in clinical database; production of unidentified clinical records in relation to the patient;
creation of a single base table for each archetype, regardless of its use in the form of slots; scalability of
database schema (stable number of database tables), even in the occurrence of recursion through slots.
