A less compact item generally occupies more volume of space, in comparison to its actual weight.The volumetric or dimensional weight is calculated and compared with the actual weight of the shipment to determine which is greater; the higher weight is used to calculate the shipment cost.
I have seen several ways using an Is Valid() and other discussions about enforcing in the constructor so the entity is never in an invalid state, or using preprocessing and postprocessing, and others using Fluent Validation api, how invariants impact DRY and SRP. You can annotate your domain objects and use that data for validation. Employees need a name We know that in the real-world an employee must always have a name.
Can someone give me a good example of where to put these sorts of checks, when using a App Service, Bounded Context, Domain Service, Aggregate Root, Entity layering. It is impossible for an employee not to have a name.
Bizagi offers the possibility to trace errors in the Processes workflows (to control and diagnose potential errors) so that administrators can ascertain if the business rules, validations, interfaces invocations, or the Process itself needs to be modified.
This is a powerful functionality for Business Rules in particular to aid in the understanding and detection of those behaviors that require adjustment.
The volumetric weight is calculated by using a conversion factor (in order to be comparable to the real weight) which we will assume is always the same and is equal to "4000", so the volumetric weight is obtained by using the following formula: You might want to verify every step of the cost calculation to ensure its correct execution.
To configure the Business Rule's traces follow the next steps: 1. In this example we will define an expression associated with a button in the Form of the Entity the Cost per Pound based on the destination country.In other words, one cannot 'construct' an employee without specifying its name. We also know that an employees name cannot change - so we prevent this from even happening by creating a private setter. NET type system to verify your employee is a very strong form of validation.Valid names have some rules Now it starts to get interesting. Let's just take the simplistic route and assume that a valid name is one which is not null or empty.Object to be traced: The trace text identifies the trace object (attribute or variable) in the log file (trace file).The object to be traced can be an attribute selected by a navigational XPath expression, a function, or a variable.In the code example above, the following business rule is not validated against.
