Database techniques for Information

EAST experimental uses MDSplus database for various data storage.The user accesses the data through the API it provides.MDSPlus stores abundant experimental data, but lacks a resource directory, which makes it difficult for users to have a quick overview of experimental data.
This paper proposes a solution to the Metadata Database based on MongoDB.Firstly, the system uses C ++ language to...
The key to developing integrated modeling and data analysis tools is to realize data exchange between different data sources (experimental database, IO for simulation code, etc.). A data integration toolkit (SpDB) was developed to access different data sources using a global unified schema defined by the ITER Physical Data Model. Data consists of the data schema and data format. The definition...
FAIR data, that is making data findable, accessible, interoperable and reusable, is becoming
increasingly adopted across a number of disciplines for many reasons. Within the fusion
community, at least with regards to experimental data, while each site has elements of the
FAIR principles, there is a lack infrastructure providing harmonised search and access
mechanism for data at multiple...
Currently, largely for historical reasons, almost all fusion experiments are using their own tools to manage and store measured and processed data as well as their own ontology. Thus, very similar functionalities (data storage, data access, data model documentation, cataloguing and browsing of metadata) are often provided differently depending on experiment. The overall objective of the...
Fusion-related experiments (WEST, MAST, JET, etc...) produce large amounts of data. In the future, we can expect ITER to produce an equally large amount of raw data coming from each and every shot.
Even though (fusion community as a whole) collects large sets of data, scientists suffer from a lack of an amalgamated shot catalogue and different access requirements. At the moment, finding...
Despite continued efforts to engineer a standardized infrastructure, through regular hardware and software upgrades and refactoring, the WEST CODAC still includes several subsystems based on Motorola PowerPC VME boards running LynxOS V3.1. There lies a major challenge for the years to come in maintaining and operating more than 10 such entities some of which, such as the poloidal field control...
