yourdb 0.1.0

A Python-native object database

YourDB

YourDB is a lightweight, Python-native object database designed to persist and query Python objects with schema validation and SQL-like querying capabilities.

It allows developers to define entities using Python dictionaries (or class-like schemas), insert objects, and perform filtering, updating, or deleting — all using native Python.

🔍 Features

• 🧱 Define custom entities with schema validation
• 📦 Store any Python dictionary or object (pickle-backed)
• 🧠 Functional querying with lambda conditions
• 🛠 Update & delete data using custom logic
• 💾 Persistent storage using pickle under the hood
• 🔍 Future extensibility for SQL-like syntax and class-based schemas

📦 Installation

git clone https://github.com/Dhruv251004/yourdb
cd yourdb
pip install .

🏁 Quickstart

from yourdb.yourdb import YourDB

# Create or connect to a DB
db = YourDB("my_database")

# Define entity schema (like a table schema)
schema = {
    "id": int,
    "name": str,
    "is_active": bool
}
db.create_entity("users", schema)

# Insert data
user1 = {"id": 1, "name": "Alice", "is_active": True}
db.insert_into("users", user1)

# Query data
results = db.select_from("users", lambda u: u["is_active"])
print(results)

# Update data
db.update_entity("users", lambda u: u["name"] == "Alice", lambda u: {**u, "is_active": False})

# Delete data
db.delete_from("users", lambda u: u["id"] == 1)
