In sequential storage, the data needs to accessed in sequential order i.e. availability the IMS Data Base Computer (INFOPLEX) employs a highly parallel, distributed control architecture. Data can be grouped according to a hierarchy of categories, each increasingly complex. ... A Record represents a collection of attributes that describe a real world entity. you can create a clone of a clone of a clone, and so on), which results in a n-level hierarchy of cloned objects, each with their own portion of shared and independent data storage. The data storage hierarchy includes a data catalog (60) and a plurality of data storage levels (10, 20, 40, 30). . TAPEPOOL The next storage pool in the hierarchy. A data storage hierarchy consists of multiple levels of data storage devices. These storage hierarchies are general enough for any data that lends itself to the concepts of experiments, protocols, and data collection visits. Instead, every distinct unit of data exists at the same level in a storage pool. one after the other. , h.
