Common data models and interfaces have been implemented in OBiBa to enable seamless and secure data transfer from one OBiBa application to another. As a result, OBiBa provides studies with an integrated software infrastructure that supports almost all their data management activities and more.
This OBiBa infrastructure can be used for both individual studies and study consortia.
An epidemiological study can take advantage of the whole OBiBa's stack.
Onyx can be used to automate data capture (questionnaire answers, sound recordings, instrument outputs etc.) and thus ensuring a low level of errors (data loss and inconcistencies). Onyx can automatically and securely export these data daily. The data dictionary is always associated to the data export, ensuring that no information will be lost when interpreting the collected data. The export media can be of different type to allow interfacing with various data processing systems:
The data dictionary can be prepared before or after the data importation. Data can also be transformed by developing derivation algorithms for data cleaning and quality checks. The participants' data can also be enriched with other type of information: drug registry, geographical area metrics etc.
The specificity of Opal is also that participant identifiers can be compartmentalized for a better privacy and to avoid data collusion: the same participant can have one ID in the data collected, another one in Opal storage and another one again in the data exported to a research group.
Mica is the web portal of choice for publishing data dictionaries and aggregated results. Out-of-the-box search capabilities of Mica allow researcher to explore study's variables and data profiles that could match their project needs. Data access requests can also be submitted and evaluated.
Obiba offers a unique software solution to support data collection, harmonization and federation. As depicted in the figure below:
Real examples of such OBiBa federated and harmonized database is described in CPTP and BioSHaRE user stories.
To set up or evaluate your own federated database infrastructure using OBiBa, follow the Data Harmonization and Database Federation Tutorial .
