MVI Design Pattern

MVI Design Pattern

The Model View Intent pattern applied to much of modern reactive design, it is a super set of several multimodal design patterns, much better than the MVC patterns of the earlier era, and better than MVP and MVVM.
Reactive++ is a pattern I introduced that goes beyond Rx, in Rx data is generalized as data streams, iterable with patterns.

Operators lead directly to provability, in Rx++ Operators are generalized to mathematical operators and formal definitions. Since, for example, in the examples in the publication above, a bag of words can be mapped formally to a set definition, and can be converted to a Rx and Rx++ definition by set equivalance, in a TLA+ specification, thus Rx++ leads to a formal provable definition of a reactive design, in a spectrum to provable computing, providing a framework for provable machine learning.

All reactive design is amenable in multimodal interactions to the MVI pattern.

We present an example of a Bag of Wiki stories with Boyau++ using XDoclet.

WS1 = " /*Story of a cat named Monitor Tabby and a Capybarra named Capybarra,
*Tabby says, we need to integrated APIs with Bayou++, as a search API with cloud *architecture, micro + cloud?
*Capybarra says, like this XDoclet2 metadata
*@jdo:persist

  • @jdo:identity-type application
  • @jdo:objectid-class TestDoclet$$Id
  • @jdo:requires-extent false
  • @jdo:extension vendor-name="kodo" key="table"
  •                     value="DOCLET_TEST_TABLE"
    
  • @ejb.bean
  • name="CodeGeneratorService"
  • jndi-name="CodeGenerator"
  • type="Stateful"
  • @ejb.resource-ref
  • res-ref-name="jdbc/CodeSource"
  • res-type="javax.sql.Datasource"
  • res-auth="Container"
  • @weblogic.resource-description
  • res-ref-name="jdbc/CodeSource"
  • jndi-name="CodeDS"
  • @author Anil Dr Bheemaiah

*Monitor Tabby says, great, we have defined a jdbc data source and a stateful *EJB, so we populate the database for model driven development? Just add a Boyou *like API search for a query and a cloud function template with a find and replace *function with key value pairs for each parameter?
*Capybarra adds, that it is that simple, to be continued in the next story!
