Denis Database
A lightweight Java cache and data engine
This site turns the project’s scattered README information into a clearer product-style documentation experience.
Architecture
How the Denis project is organized
The upstream repository structure shows Denis as a runtime-oriented Java project with packaging, setup scripts, driver experiments, and a server path. This page summarizes the practical architecture visible from the repo and README.
Observed structure
| Item | Details |
|---|---|
| Primary language | Java is the dominant implementation language in the upstream repository. |
| Execution modes | Local jar execution, CLI mode, and server mode are all first-class entry points. |
| Install assets | Shell and batch scripts help install wrappers and start the app without manually typing the jar command every time. |
| Runtime files | The README explicitly calls out denis.properties, denis.toml, ddb.json, pawd.dat, and logs/. |
| Data APIs | The project exposes typed action classes and also a SQL-style command protocol for remote interaction. |
Practical interpretation
The repo is best understood as a small deployable data system rather than a single Java package.
- The install scripts suggest the project wants to be used from release bundles, not only from source checkouts.
- The server and CLI modes mean operators and developers have separate runtime entry points.
- The action classes cover in-process data manipulation patterns, while SQL-like commands cover remote or protocol-driven usage.
- Configuration and generated files living beside the app indicates a filesystem-aware operational model.
