They can be partitioned into horizontal units called shards.
Armstrong's axioms govern the inference rules for this kind of structure. They can be partitioned into horizontal units called shards. The logical consistency of these structures can be improved by converting them into Boyce-Codd form, one of the many normal forms for these entities. Atomicity, durability, consistency, and isolation comprise the ACID properties of these structures. Items organized in these structures can be stored in (*) column-oriented or row-oriented formats. They are typically accessed by using queries through a language like SQL. For 10 points, name these computer programs that store large collections of information.
