Document Operations
class DocumentStore:
"""Document database operations"""
def __init__(self, connection):
self.db = connection
def insert_document(self, collection: str, document: dict):
"""Insert a document"""
return self.db[collection].insert_one(document)
def find_documents(self, collection: str,
query: dict = None,
projection: dict = None):
"""Query documents"""
return self.db[collection].find(query or {}, projection)
def update_document(self, collection: str,
query: dict, update: dict):
"""Update documents"""
return self.db[collection].update_many(query, update)
def aggregate(self, collection: str, pipeline: list):
"""Run aggregation pipeline"""
return self.db[collection].aggregate(pipeline)
Aggregation Pipeline
class AggregationExamples:
"""Aggregation pipeline examples"""
