SciDB
SciDB is a uniquely efficient architecture for highly dimensional, multi-modal structured data along with metadata. It’s a scientific database engine with a native multidimensional array data model designed for rapid data selection both by metadata tags and values. Comprehensive schemas capture and connect all the metadata, facets, annotations, and raw & processed data for each data modality. Guaranteed data integrity and reproducibility for dynamic, multi-user, multi-site deployments with its distributed, transactionally-safe (ACID) and logging.
The scidb package helps R interact with SciDB by directly running SciDB queries using the native array functional language (AFL) and optionally returning results as data frames.
