'''Object-Oriented Modeling''', or OOM, is a [[computer model|modeling]] paradigm mainly used in [[computer programming]]. Prior to the rise of OOM, the dominant paradigm was [[functional programming]], which emphasised the use of discreet reusable code blocks that could stand on their own, take variables, perform a function on them, and return values.

The Object-Oriented paradigm assists the programmer to address the complexity of a [[problem ___domain]] by considering the problem not as a set of functions that can be performed but primarily as a set of related, interacting Objects. The modeling task then is specifying, for a specific context, those Objects (or the Class the Objects belongs to), their respective set of Properties and Methods, shared by all Objects members of the Class. For more discussion, see [[Object-oriented analysis and design]] and [[Object-oriented]] programming]]. The description of these Objects is a [[Logical schema|Schema]].

As an example, in a model of a '''Payroll System''', a '''Company''' is an Object. An '''Employee''' is another Object. '''Employment''' is a Relationship or Association. An '''Employee Class''' (or Object for simplicity) has Attributes like Name, Birthdate, etc. The Association itself may be considered as an Object, having Attributes, or Qualifiers like Position, etc. An '''Employee Method''' may be Promote, Raise, etc.
