"At a high level, variables are containers that store data. At a low level, variables are named allocations of memory. If a variable is like a box, then a data type is like a box size, and the data is content."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
