Separate data schema from data representation
With data separated from code and represented with generic and immutable data structures, now comes the question of how do we express the shape of the data? In DOP, the expected shape is expressed as a data schema that is kept separated from the data itself. The main benefit of Principle #4 is that it allows developers to decide which pieces of data should have a schema and which pieces of data…
Data is immutable
With data separated from code and represented with generic data structures, how are changes to the data managed? DOP is very strict on this question. Mutation of data is not allowed! In DOP, changes to data are accomplished by creating new versions of the data. The reference to a variable may be changed so that it refers to a new version of the data, but the value of the data itself must never…
Represent data with generic data structures
When adhering to Principle #1 of DOP, code is separated from data. DOP is not opinionated about the programming constructs to use for organizing the code, but it has a lot to say about how the data should be represented. This is the theme of Principle #2.
Separate code from data
The first principle of Data-Oriented Programming (DOP) is a design principle that recommends a clear separation between code (behavior) and data. This may appear to be a FP principle, but in fact, one can adhere to it or break it either in FP or in OOP:
Principles of Data-Oriented Programming
This article is an excerpt from my book about Data-Oriented Programming. More excerpts are available on my blog.
Reading the present moment
This is an experiment I am doing about introducing a bit of self-referential stuff in Chapter 13 of "Data-Oriented Programming.
