Where possible, administrative controls should be combined with other control measures. [17] Examples of administrative controls include: Implementing job rotation or work-rest schedules to limit individual exposure. Establishing a preventive maintenance program to ensure equipment is functioning properly.
For example, a command hierarchy has among its notable features the organizational chart of superiors, subordinates, and lines of organizational communication. Hierarchical control systems are organized similarly to divide the decision making responsibility. Each element of the hierarchy is a linked node in the tree. Commands, tasks and goals ...
Hierarchical Data Format (HDF) is a set of file formats (HDF4, HDF5) designed to store and organize large amounts of data.Originally developed at the U.S. National Center for Supercomputing Applications, it is supported by The HDF Group, a non-profit corporation whose mission is to ensure continued development of HDF5 technologies and the continued accessibility of data stored in HDF.
Some file systems, or layers on top of a file system, allow a program to define a record so that a program can read and write data as a structure; not an unorganized sequence of bytes. If a fixed length record definition is used, then locating the n th record can be calculated mathematically, which is relatively fast compared to parsing the ...
A hierarchical file system contrasts with a flat file system, where information about all files is stored in a single directory, and there are no subdirectories. Almost all file systems today are hierarchical. What is referred to as a file system is a specific instance of a hierarchical system. For example, NTFS, HPFS, and ext4, all implement a ...
Network structure: network structures also organizes data using nodes and branches. Unlike hierarchical structure, each child node can be linked to multiple, higher parent nodes. Relational structure: a relational database organizes its data in a series of related tables. This gives flexibility as relationships between the tables are built.
Data flowcharts, showing controls over a data-flow in a system; System flowcharts, showing controls at a physical or resource level; Program flowchart, showing the controls in a program within a system; Notice that every type of flowchart focuses on some kind of control, rather than on the particular flow itself.

Data hierarchy refers to the systematic organization of data, often in a hierarchical form. Data organization involves characters, fields, records, files and so on. [1] [2] This concept is a starting point when trying to see what makes up data and whether data has a structure. For example, how does a person make sense of data such as 'employee ...
