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.

They have no schema and do not support either joins or atomicity, consistency, isolation, or durability ACID properties [ 24 ]. Query data items are constrained as indexed columns, in order to improve performance. The different scalability of the DBMSs is another factor playing an important role: Shows most frequent query throughput and response times in concurrent execution in MongoDB.

However, when medical practitioners make primary use of medical information clinical practicethey tend to visualize normalized medical information regarding a single patient.

NoSQL systems scale horizontally scaling-outhowever, i. Thereafter the most executed lso priority query average throughput and the 1606-4 response times of the three queries were calculated.


This model has a well-established theoretical background which has been well studied and understood, and has long guaranteed consistency and efficiency within database systems. NoSQL approaches can be faster and more scalable when data sizes are extremely large, or when there are no internal document references that can damage speed or data consistency.

There are over different NoSQL databases, grouped into the following four categories: This is a strict requirement of medical information: Using this methodology, archetypes are mapped into tables, and archetype basic data types are mapped as common columns.

A whole document may also be reconstructed, but this is a fairly slow task, at least in ORM.

In fact we have a complex and over specified schema. However, since some structural information from the original extract is lost during the process of building the simplified relational schema, it is not possible to recover the original extract as it was before its storage. The relational model for database persistence [ 1317 ] is a very well established and mature methodology, which is paradigmatic.

A Java multithread application was constructed, with three main threads representing three of the presented queries competing for CPU Central Processing Unit use.

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. This is due to several factors affecting technical, syntactic and semantic interoperability between information systems, including the inevitable rapid change and evolution of medical knowledge.


The very high number of tables generated in the pure relational ORM approach induces many expensive join operations, resulting in a higher computational cost as the size of the database grows and showing a much higher linear slope. Whilst MySQL and MongoDB yield very similar results in the small extracts database they diverge considerably in the big 20, extracts database, the relational being much slower than the non-relational.

This table also shows the average size in memory of one extract in the database and the average size of one extract in XML format.

We also provide a short description of two separately developed and related methodologies. Several improvements within the relational model have been proposed and used.

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 ]. Regarding primary use, a probable clinical practice scenario is that formed of several extracts from a oso patient, with which the medical professional is working at any given time.
