ARCHITECTURE

System Overview

Execution is built around ExecutionContext, a shared runtime interface for execution, storage, locking, indexing and account services.

00 / EXECUTION CONTEXT

One runtime interface through the system.

ExecutionContext connects programs with runtime services. It gives every execution path the same view of accounts, files, locks, indexes and storage.

MULTIVALUE / RELATIONAL

MultiValue vs. Relational (SQL) Databases

For a quick technical perspective, MultiValue handles data differently than traditional Relational Database Management Systems (RDBMS):

Feature	MultiValue Database (MVDBMS)	Relational Database (RDBMS)
Data Structure	Multidimensional / Non-1NF (allows arrays inside fields)	Flat 2D tables / 1NF (one specific fact per cell)
Joins	Rarely required; complex sub-values sit inside the record	Heavily dependent on join tables across unique IDs
Schema	Flexible; dictionary files define interpretation over raw records	Rigid; concrete, pre-defined schemas required before entry
Performance	Extremely fast read/write for complex nested business profiles	Slower on deep analytical queries that involve massive join paths

SECURITY MODEL

Persistent identity and least privilege.

RightMV separates account entry, file-development access and system administration while retaining the account behavior expected by established MultiValue applications.

01 / EXECUTION PATHS

Execution paths

The same MV BASIC program can move through different execution paths while sharing accounts, locking, indexing and storage services.
