+##  Database
+
+* A database is a structured collection of data.
+* It allows for the storage, retrieval, modification, and deletion of data in an organized manner.
+* Databases come in various types, including relational and NoSQL. Relational databases organize data into tables, which are interconnected.
+* Each table represents a related data collection and is organized into rows and columns.

+## SQL stands for Structured Query Language.
+
+It's a programming language that stores and processes information in relational databases.
+
+### Types of SQL Statements
+
+* DDL (Data Definition Language): DDL statements are used to define, modify, and remove database structures, but not the data within them. Common DDL statements include CREATE, ALTER, and DROP.
+* DML (Data Manipulation Language): DML statements manage data within schema objects. They include SELECT, INSERT, UPDATE, and DELETE.

+### To ensure DuckDB is installed correctly, launch your jupyter Notebook and try importing the DuckDB module:
+
+```python 
+pip install duckdb
+```
+### If no errors occur, DuckDB is successfully installed and ready to use.
+___
+### In your Jupyter Notebook, import duckdb by running
+```python 
+import duckdb
+```
+### For this tutorial, we will be using a pre-configured Duckdb Database. 
+### Let's download the database file:
+```python 
+!wget --content-disposition https://arizona.box.com/shared/static/uozg0z86rtdjupwpc7i971xwzuzhp42o.duckdb
+```
+
+### Connect to the database using: 
+```python 
+conn = duckdb.connect(database='/content/my_database.duckdb', read_only=True)
+```
+
