From Wikipedia, the free encyclopedia. A data mart is the access layer of the data warehouse environment that is used to get data out to the users.

Most species of slugs are generalists, feeding on a broad spectrum of organic materials, including leaves from living plants, lichens, mushrooms, and even carrion. Some slugs are predators and eat other slugs and snails, or earthworms.
The Slugs Eating. Slugs belong to a large group of animals called the Molluscs. This group includes clams, squid, and octopus, oysters as well as slugs and snails. Slugs are most closely related to snails; in fact, slugs are generally thought of as snails without shells. Slugs vary in length, depending on species and age, from 1/4 inch to as much as 10 inches. They are elongate with a prominent dorsal, fleshy mantle that encloses the vital organs.
