Character - a letter
Field - a group of characters. Like letters make up a word.
Record - a group of fields describing a single entry. Like if we put you into a phone book we would use your name, address and phone number (the fields) of you record.
File - a group of records. Like the A's in the phone book.
Database -groups of related files. The phone book.
A hierarchy includes different levels of authority or importance within an organization or system. Each level has its own set of responsibilities and decision-making power, with higher levels typically having more authority than lower levels. Hierarchy helps to establish clarity in reporting relationships and promote efficient communication and decision-making.
A pyramid with levels is a geometric figure characterized by a polygonal base and triangular faces that converge at a single point called the apex. The structure is often divided into horizontal sections or levels, each representing different layers of hierarchy or categories. This concept is commonly used in various fields, such as organizational structures, Maslow's hierarchy of needs, and data representation. Each level typically signifies a different rank or importance, with the base representing foundational elements and the apex symbolizing the highest achievements or values.
A ziggurat typically has three to seven levels or stories. Each level represents a different tier and holds significance in the hierarchy of the structure.
The biological hierarchy refers to the different levels of classification from domain to species (eight levels). The three domains are Bacteria, Archaea, and Eukarya, while the types of species number in the high hundred thousands or low millions. Each organism can be classified into a race and then taxonomically into species, genus, family, order, class, phylum, kingdom, and then domain.
Nested buffers refer to a situation where a system has multiple levels of buffers or storage spaces within each other. This can create a hierarchy of buffers, with data passing through multiple stages of buffering before being processed. Nested buffers are commonly used in computing systems to help manage data flow and optimize performance.
A hierarchy is a list of ranks, each more important and more respected than each other.

They all describe data set or data sets,hey tell you how far apart they are from each other.
An irregular bifurcating hierarchy is a structural model often used in organizational theory and systems analysis, characterized by a branching, tree-like pattern where entities split into sub-entities at varying levels. Unlike a regular hierarchy, where each level has a uniform number of sub-levels, an irregular bifurcating hierarchy allows for asymmetry and variation in the number of branches or divisions. This model can be seen in natural ecosystems, social organizations, and certain computational structures, where complexity and diversity are inherent. It highlights the dynamic relationships and interactions among different levels within a system.
A control account & work package are terms used to describe the levels of work that are part of the WBS
Treemaps are important to programmers because they create a visualization of the program. It displays data in a hierarchy using rectangles that are nested inside of each other.
