You might be able to identify cross-cutting concerns in a monolith, but in a service-orientated world they should melt away into specific implementations. Gladys S.W. Business rules are intended to assert business structure or to control or influence the behavior of the business. The catch is that the separation between business logic and other parts of the system is not necessarily that clear. There is an important difference between the two.

Can I combine two 12-2 cables to serve a NEMA 10-30 socket for dryer? Business Rules vs. Business Logic. This is why it is surprising that only during the last couple of years the subject of Business Rules Management got the attention of a wider audience.

(https://en.wikipedia.org/wiki/Business_rule), I consider that logic is programming and thus associated more with IT than business leaders and domain experts, and therefore, Business Logic is the embodiment of (some of) Business Rules in IT systems and applications.

Over the years I have built a lot of stuff including web sites and services, systems integrations, data platforms and middleware. In reality it often refers to the poorly-defined “gloop” that sits between user interfaces and databases in layered architectures. Configuring rules and business logic. You can create business rules and recommendations to apply logic and validations without writing code or creating plug-ins.

Business logic is often divided into two different types: Business rules and Use cases. Why would a company prevent their employees from selling their pre-IPO equity? The interfaces between each layer tend to be relatively chatty and pass data around in small chunks so they can struggle to distribute processing.

I consider that Business Rules are the business's rules, that is, policies determined by the business, i.e. I think "domain logic" is more general and would be preferable.

And even if i were to go along with your definition, its still silly because the code is the expression of the logic/rules which the business decided upon; IT just makes the system obey the rules the business sets forth. Anything that involves some kind of transformation or workflow just gets dropped into the tier by default. This article presents five pragmatic tests for knowing when you have identified a true business rule… Then is the logic itself the rule or is it the different sums of some rules for different situations? The execution of a single stored procedure may be faster than executing the equivalent logic with the application code. “Legacy” is often used a pejorative term to describe any long-lived code base that a development team finds distasteful to work with. Business logic or domain logic is that part of the program which encodes the real-world business rules that determine how data can be created, stored, and changed. My current focus is on providing architectural leadership in agile environments. Separating a system into conceptual layers or tiers can give rise to inflexible solutions. That's usually a bad thing as it is hardly reusable. The problem with this kind of generic solution is that it is a mistake to imagine that system architecture can be abstracted from infrastructure. Business logic in the database makes a lot of sense, and is often even unavoidable. I'm not the only one that commented that domain logic migh be to DDD specific either.

No, it isn’t. This 40X (5 rules vs. 200 lines) is proportional - even in a medium sized system, this is tens of thousands of lines of code. System tends to be inefficient as much of the work being done involves transferring data between layers rather than implementing business rules. 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..
