The main advantages of the Entity-Attribute-Value design are flexibility and effective entity-centered data retrieval. The main disadvantages are complicated front-end programming needed to display data in a conventional layout that the user understands and less-efficient attribute-centered queries. The Internet offers unique opportunities for database deployment, eliminating problems of user-interface deployment. Furthermore, Web forms may be generated in a completely-generic fashion during run time from metadata describing the semantic structure of clinical information stored in the database. Conclusions: The Entity-Attribute-Value model is useful for generic design of clinical databases. Depending on the specific requirements of the application, more or less complex metadata models may be applied. %M 14713655 %R 10.2196/jmir.5.4.e27 %U //www.mybigtv.com/2003/4/e27/ %U https://doi.org/10.2196/jmir.5.4.e27 %U http://www.ncbi.nlm.nih.gov/pubmed/14713655
