How innovative is Clojure as a Lisp dialect from Lisp expert's perspective?

the best innovative: Clojure is a functional programming language based on relational database theory.

```

               Clojure -> DBMS, Super Foxpro

                   STM -> Transaction，MVCC

Persistent Collections -> db, table, col

              hash-map -> indexed data

                 Watch -> trigger, log

                  Spec -> constraint

              Core API -> SQL, Built-in function

              function -> Stored Procedure

             Meta Data -> System Table

```

I don’t care about static or dynamic types, nor about FP, LP, or OO. For me, they are overly complex, unreliable, and unscientific. I think they are very bad and upset me.

The production methods and business management ideas of large industries are also more mature than FP&OO. I have used them as programming ideas.

I think that RMDB is the simplest and most reliable in theory and practice, and it is the most rigorous, long-term, high-stress test in critical situations.

Before using clojure, I was a Foxpro programmer. I used clojure as a super Foxpro, and I also used it successfully in the field of WebApp and R language mixed programming. I will continue to apply this routine to the AI field in the future.

The main development goal of clojure is to write the database. The development idea is actually from the database, not the FP.

But... RDMBs are often statically typed (you specify the column type when creating it), and strongly typed (they often don't do auto-conversions of data types.)

With reference to the database, as long as I use spec to strictly define (standardization) the core data model, I can ensure the correctness of the system.

I've turned the traditional work of ensuring code correctness from in-code type system validation to data self-validation. Turn the work into verifying the core data model instead of validating the input and output data types of the function.

A system requires only a few core data models, and development is built around the core data model.

Persistent data structures ensure that the modification of the immutable big data model are high performance and memory efficient.

In addition, using my pure function pipeline data stream (https://github.com/linpengcheng/PurefunctionPipelineDataflow) makes debugging, parallelism and extension very simple.

Similar to industry, verify that all finished products meet the standards before entering the warehouse.

Also similar to databases, verify their compliance before data enters the database.

That is "Data as a service, Warehouse as the core, operates around it".

I think their point is that it's the ability to express relational algebra in a natural way that's important, and the static/dynamic types thing is orthogonal to that.
