Database Architecture Course Orientation & Context

Important Questions for the course What is a database? What is a database management system? What is a database system? What is the semantic hierarchy of database models? What is a relational database? How do we create a database system? How do database management systems work? Why is database architecture important? What are the various architectures associated with database systems? What are the scalable and extensible features of database systems? How do you manage a database system?

Two-tier architecture implementation of a database system DBMS “Instance” Physical Database

The Study of Database Architecture ….the components of the Database System 1.How do we build a relational model for the database? 2.How do we physically implement the relational model? 3.How do we manage the physical database? 1.What is a DBMS? 2.What is the DBMS architecture? 3.How are transactions and queries processed? 1. How do users interact with the database?

The DBMS as an application Utilizing the CPU & OS to do work…..
