There is also a standard for a Java Runtime API for rule engines JSR-94. OMG Business Motivation Model (BMM): A model of how strategies, processes, rules, etc. fit together for business modeling
Codd's twelve rules [1] are a set of thirteen rules (numbered zero to twelve) proposed by Edgar F. Codd, a pioneer of the relational model for databases, designed to define what is required from a database management system in order for it to be considered relational, i.e., a relational database management system (RDBMS).
According to the white paper by the Business Rules Group, [1] a statement of a business rule falls into one of four categories: Definitions of business terms; The most basic element of a business rule is the language used to express it. The very definition of a term is itself a business rule that describes how people think and talk about things.
Business rules are abstractions of the policies and practices of a business organization. In computer software development, the business rules approach is a development methodology where rules are in a form that is used by, but does not have to be embedded in, business process management systems.

Business logic in theory occupies the middle tier of a 3-tier architecture. Business logic could be anywhere in a program. For example, given a certain format for an address, a database table could be created which has columns that correspond exactly to the fields specified in the business logic, and type checks added to make sure that no invalid data is added.
One well-known definition of what constitutes a relational database system is composed of Codd's 12 rules. However, no commercial implementations of the relational model conform to all of Codd's rules, [4] so the term has gradually come to describe a broader class of database systems, which at a minimum:
Business rules represent the primary means by which an organization can direct its business, defining the operative way to reach its objectives and perform its actions.. A rule-based approach to managing business and the information used by that business is a way of identifying and articulating the rules which define the structure and control the operation of an enterprise [1] it represents a ...
