- Contact TAs if they don't show up for scheduled hours.
- Course focus: Understanding how data storage works in data management systems, focusing on Relational Database Systems.
- Database tools to be used: MySQL.
- Data storage focus: Persistence of data beyond program use and system shutdowns.
- Databases are a collection of related data.
Why this Class?
- Databases power many applications: Banking, social media, search engines, and more.
- Data is growing rapidly across various fields like genomics, astronomy, medicine, and meteorology.
- Data growth will outpace computation, and data processing is a future bottleneck.
- Systems for efficiently managing data at scale are foundational for modern computing.

- Installation of database-related software (WAMP/MAMP, MySQLWorkbench). Specific instructions will be given.
Database Concepts
- Databases: Collections of related data for a specific purpose (Accounts, Payroll, Students, Amazon Products, Airline Reservations)
- DBMS (Database Management System): Software to create, maintain, and manage a database (DB2, SQL Server, Oracle, MySQL, PostgreSQL).
Client/Server Structure
- A simple web based system with user requests.
- Requests routed through a Web server.
- SQL queries processed by the Database Server (DBMS).
- Web service for interaction to and from the database to manage multiple clients.
Relational Model
- Database as a collection of relations (tables).
- Tables contain rows (tuples) and columns (attributes).
- Tables represent structured information.
- SQL refers to relations as tables.
Relation Definition
- Relation: A set of tuples or rows with attributes.
- Schema: Defining the attributes, including data types (such as integer and string).
- Instance: The actual data contained in a relation. (Example of a relation of auto part supplier).
Hans Rosling Exercise
- Background on the need for analysis which involves plots and 120,000 data points.
- Attributes to store in a database for this sort of analysis (e.g., data, time series, geographic location)
- Design of Relational schema to support this kind of analysis (multi-table schemata recommended).
