In some cases, menu options or functions may be made visible or hidden depending on a user's permission level; this kind of user interface is referred to as permission-driven.

  7. Partition (database) - Wikipedia

    en.wikipedia.org/wiki/Partition_(database)

    This strategy enables the sequential access to a relation to be done in parallel. However, the direct access to individual tuples, based on a predicate, requires accessing the entire relation. Hash partitioning : applies a hash function to convert skewed data into uniform distributions for even load distribution across partitions.

  8. Data remanence - Wikipedia

    en.wikipedia.org/wiki/Data_remanence

    Data remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage media that allow previously ...

  9. Server Message Block - Wikipedia

    en.wikipedia.org/wiki/Server_Message_Block

    This means that the client may now assume that it is the only process with access to this particular file, and the client may now cache all changes to the file before committing it to the server. This is a performance improvement, since fewer round-trips are required in order to read and write to the file.
