Synopse Open Source

One year ago, we already made a quick presentation of Domain-Driven Design, in the context of our mORMot framework.
After one year of real-world application of those patterns, it is now time to give more light to DDD.

Let's continue with part 4, which will define Domain-Driven Design as could be implemented with our Synopse mORMot framework

One year ago, we already made a quick presentation of Domain-Driven Design, in the context of our mORMot framework.
After one year of real-world application of those patterns, it is now time to give more light to DDD.

Let's continue with part 2, which will define Domain-Driven Design high-level model principles.

In Delphi, the record has some nice advantages:

• record are value objects, i.e. accessed by value, not by reference - this can be very convenient, e.g. when defining a Domain-Driven Design; 
• record can contain any other record or dynamic array, so are very convenient to work with (no need to define sub-classes or lists); 
• record variables can be allocated on stack, so won't solicit the global heap; 
• record instances automatically freed by the compiler when they come out of scope, so you won't need to write any try..finally Free; end block.

Serialization of record values are therefore a must-have for a framework like mORMot.

In recent commits, this JSON serialization of record has been enhanced.
In particular, we introduced JSON serialization via a new text-based record definition.

Implementing Domain-Driven-Design (DDD) is one goal of our mORMot framework.

We already presented this particular n-Tier architecture.

It is now time to enter deeper into the material, provide some definition and reference.
You can also search the web for reference, or look at the official web site.
A general presentation of the corresponding concepts, in the .NET world, was used as reference of this blog entry.

Stay tuned, and ride the mORMot!
