Along with a number of other types of hosting capabilities that A2 Hosting has, one to add to that list is PostreSQL hosting. I am definitely new to this type of hosting and the purpose of this blog is to describe the different types of hosting to new webmasters, so here we go.

To best understand what PostgreSQL is, one must know that it is an object-relational database management system (ORDBMS) is because that is what PostgreSQL is.

Breaking down ORDBMS:

1.) It is a relational database management system. The relational management system is based on predicate logic and set theory.

a.) Predicate logic is a general term for formula systems such as first, second and infinitary logic.

i.) First order logic is breaks down sentences or mathematical equations into subject and predicates, with the predicate defining the subject.

ii.) Second order logic is an extension of first order logic as it allows for further explanation of the subject.

iii.) Infinitary logic is a statement that can be infinitely long

b.) Set theory is the theory of the sorting of objects into different groups (or you could say “sets” in this instance).

From all of these definitions, I think the easiest way to break this down is relational management is simply grouping objects and defining those objects by creating “relationships” as designated in the term relational management.

2.) It allows software developers to mix together their custom sets of data and specific tasks to be performed associated with that data.

PostgresSQL is not controlled by any one company and it is made available for everyone, allowing developers to edit it in any way that they see fit.
