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. The data mart is a subset of the data warehouse and is usually oriented to a specific business line or team. Whereas data warehouses have an enterprise-wide depth, the information in data marts pertains to a single department.
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.
It depends on the type of snails. Garden snails usually eat plant material like beans, lettuce and tomatoes. Some land snails like eating fungus more than plants, and some like eating almost anything dead and rotting. Many of the marine snails are carnivores and eat worms, small fish, small crabs, or other snails.
