Queries of increasing complexity were performed on these databases, against the information contained in the problems list. Many DBMSs build structure 13606- range indexes automatically. They have no schema and do not support either joins or atomicity, consistency, isolation, or durability ACID properties [ 24 ]. However one of the former presents a much steeper slope than two of the latter.

ISO 13606 specifications

Response times to these queries io calculated, in order to compare the performance and the algorithmic complexity of the three DBMSs methodologies see below. NoSQL database systems have recently attracted much attention, but few studies in the literature address their direct comparison with relational databases when applied to build the persistence layer of a standardized medical information system. There are numerous whitepapers, blog entries and commentaries on the advantages of NoSQL database systems [ 28 ].

Their figures will be shown in the results section, in order to provide a broad perspective and an insight into database persistence on standardized medical information.

Comparing the performance of NoSQL approaches for managing archetype-based electronic health record data. This is because MongoDB query execution contains a considerable amount of time consuming administrative and communication tasks that are optimized in an execute-once fashion in the concurrent version, concentrating CPU execution time in the query itself.

Publicly Available 1360-4 You may be interested in this related standard Health records You may be interested in this related standard. The special nature of medical knowledge that requires the separation into two 1306-4 of the dual model can have a profound effect on the way information in EHR documents is structured and how it is stored logically and physically in a database management system. Find initial date, resolution date and severity of a single problem of a single patient. This research covers an investigation into the appropriateness of relational and NoSQL database systems under different situations and perspectives.

The whole extracts documents or their subsets returned by the NoSQL system are to be retrieved and visualized by the medical professional.

Direct comparison with our results is not possible iao database sizes are different as is the total number of extracts. Column-based database systems are based on the fact that conventional row-stored systems might need to read in unnecessary data, when performing reads.

Thus we can query the medical information present in the extracts but we cannot recover them in their original state. The queries selected were Q1, Q3 and Q4, for 13606-44 main reasons: NoSQL databases have attracted the attention of practical database system developers [ 20 ]. Ercan MZ, Lane M. Jso the case of MongoDB isp an extremely big database, its apparent flatter linear behaviour would favour it versus a relational approach, in which joins of ever growing relational tables would produce high-slope linear complexity.

It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. Int J Adv Softw. EN Archetype Definition Language files. However, the complex structure of the information adopted by the normalized EHR documents may cause the direct application of the relational model following this structure Object Relational Mapping, ORM [ 14 ] to be complicated and inefficient.

ISO/TS 13606-4:2009

Received Oct 13; Accepted Jul All previous persistence 136066-4 have been based upon an underlying relational database system. Security This document has been re-assessed by the committee, and judged to still be up to date. In the specific case of standardized medical information, our problem is not the lack of a schema.

Consequently if a CRUD operation is launched from a Java application, in order to query the extracts database, and if a table-like output is desired, the JSON output documents must be parsed and processed as a subsequent part of the queryin order to produce such relational table-like results.

There are several pros and cons, but in many cases a trade-off solution is best.

Find initial date, resolution date and severity of all problems of a single patient. Normalized medical information visualization.

ISO/PRF – Health informatics — Electronic health record communication — Part 4: Security

Queries Q1, Q3 and Q4 refer to problems and characteristics of problems of a single patient and are thus to be typically formulated in a scenario of clinical practice i. ORM implies the construction of many tables related through foreign keys representing the complex structure of the extract XML file and may damage performance.

NoSQL systems scale horizontally scaling-outhowever, i. A MongoDB query might thus be considered as another form or as a first step in document visualization. Additional indexing columns are added for attribute values in order to provide some query ability. Health Level Seven International.

It optimizes query execution in concurrency and stands as an impressive database system from this perspective. Javascript object notation JSON. Managing data in healthcare information systems: The structure of the information as stated in the archetypes is used to define the new relational schema, using these mappings.

Footnotes Electronic supplementary material The online version of this article doi: For instance, the field representing the unique identifier of a patient is a very important attribute to be indexed in queries regarding one single patient, such as Q1, Q3 and Q4.

On the other hand the much flatter linearity of the NoSQL systems merits further research, in order to decide the appropriateness of document-based database approaches. Being a semi-structured database, it stores data in the form of entire XML documents, so it may also be considered a document-based NoSQL database [ 19 ].
