  Cell stores provide a relational-like, tabular level of abstraction to
business users while leveraging recent database technologies, such as key-value
stores and document stores. This allows to scale up and out the efficient
storage and retrieval of highly dimensional data. Cells are the primary
citizens and exist in different forms, which can be explained with an analogy
to the state of matter: as a gas for efficient storage, as a solid for
efficient retrieval, and as a liquid for efficient interaction with the
business users. Cell stores were abstracted from, and are compatible with the
XBRL standard for importing and exporting data. The first cell store repository
contains roughly 200GB of SEC filings data, and proves that retrieving data
cubes can be performed in real time (the threshold acceptable by a human user
being at most a few seconds).
