Manage data slices. A data slice is a logical representation of the data that is saved in the partitions of a disk. The data slice contains pieces of each user database and table. The IBMÂ® NetezzaÂ® system distributes the user data to all of the disks in the system by using a hashing algorithm. Each data slice has an ID, and is logically owned by a SPU to process queries on the data that is contained within that data slice.
Definition - What does Data Mapping mean? Data mapping is a process used in data warehousing by which different data models are linked to each other using a defined set of methods to characterize the data in a specific definition. This definition can be any atomic unit, such as a unit of metadata or any other semantic. This data linking follows a set of standards, which depends on the domain value of the data model used. Data mapping serves as the initial step in data integration.
