Relationships can be the interaction between entities, often known as parties or enterprises, including: governments, businesses, and organizations, even resources, such as natural or even unnatural resources.

Some examples of natural resources are life forms or so-called non life forms, such as water, oil, minerals, time.

Unnatural resources might be unnatural or manmade materials, or perhaps spiritual or resources that are intangible, such as goodwill or a little more tangible, but still an abstract concept, such as good credit, or a position or role in an organization, family or system. These can be rather vague concepts, but they can help define relationships.

Some relationships are parasitic, often involving one of the parties or enterprises exploiting everyone and everything, and others are symbiotic, often involving all the parties contributing to each other's betterment and/or an endeavor.

Certain cultures or regions of the world tend to encourage either parasitic or symbiotic relationships.

It is very common for the same parties or enterprises to constantly be exploited or involved in parasitic relationships, just as it is common for the same parties or enterprises to constantly be in rewarding or symbiotic relationships.

Certain religions or belief systems that tend to be more popular in certain cultures or regions of the world tend to help create an environment where either parasitic or symbiotic relationships dominate or are the normal type of relationship in the region.

Even in families relationships can be parasitic, but especially within governments, businesses, and organizations relationships can be parasitic, and examples of that are overly mean and demanding bosses that exhaust all of the employees.

The study of relationships tends to involve systems science.

Systems science and relationships involves all disciplines and/or fields of knowledge and other how they all interact together.

Comprehensive and/or overarching knowledge of many disciplines and/or fields of knowledge is important in understanding relationships and systems science.

It is best that relationships are sustainable and do not entirely deplete the resources of the weaker party.

Some think system science is the most important science.

Both environmental science and Computer Networking are forms of system science.

Systems analysts are often involved in studying the interactions and relationships of systems and making virtual models of those interactions and relationships of systems.

Defining a system and making a virtual model of it is similar to being an architect of a virtual system.

Environmental Science and Computer Networking can resemble architecture, and both can be very noble undertakings and tend to pay very well.

Both Environmental Science and Computer Networking can be about defining very abstract concepts about resources mathematically.

Ecology is often the about the study of relationships, often within systems.

Ecology can also be considered Environmental science, which is often the field is greatest demand by employers, and the Networking field is often in second greatest demand by employers, and can be considered also a form of the study of relationships, but it is more about planning the flow of information through systems, whereas, Ecology is often the study of resources interaction within systems. Both are important and complex fields of study, but Environmental science may need a more comprehensive understanding of science. System Science my NOT BE WELL COVERED IN THE POPULAR PRESS OR THE MOVIES. Relationships may be well covered, by not in an interdisciplinary fashion.

Relationships are often defined by System Science.
