A pseudo NoSQL database

RunDB

RunDb is not exactly a database. It is similar to TinyDB <https://tinydb.readthedocs.io/en/stable/>__ on storing files as json.

The main point of this library is to help the user on storing and loading data.

Philosophy

• NoSql with tools to simulate relational
• Table are fully loaded
• Query are done using python
• Data must be serializable, but no format is imposed: some data may be stored as dict, while other are mere strings
• You can specify a serialization and deserialization function to automaticly convert the values

.. code:: python

import RunDB
from pathlib import Path

db_path = Path("testRunDB")  # The folder containing the tables as json files

db = RunDB.Database(db_path)  # This will create the folder if it is missing, then loading all tables
User = db.table("user")  # Create or get table labeled as "user", it's file is called user.json
User["hello"] = {"name": "World"}

res = User.filter(lambda d: isinstance(d, dict) and "36" in d["name"])  // return a subtable

db["test"]["new"] = {"name": "new data"}

db.dump_all()  # Dump all tables

Nb: Database are simply Group of Table, We can register Tables from somewhere else or simply use a Table without Database object

Future

• add other serialization as csv or yaml
