Assignment Activity 1: Introduction to Databases

At the core of database design and development is understanding the purpose and functionality of databases. Students will explore the role of databases in storing structured data, such as customer information, product details, financial records, and more. They will learn about the advantages of using databases over traditional file-based systems, including data integrity, consistency, and security.

Assignment Activity 2: Relational Database Concepts

Relational databases form the foundation of modern database systems. Students will delve into the fundamental principles of relational databases, including tables, rows, columns, keys, relationships, and normalization. They will understand how to model data using entity-relationship diagrams (ERDs) and translate these models into relational schemas.

Assignment Activity 3: SQL and Database Querying

Structured Query Language (SQL) is a powerful tool for querying and manipulating data in relational databases. Students will learn SQL syntax and commands for creating, querying, updating, and deleting data in databases. They will practice writing SQL queries to extract specific information from databases, perform data manipulation operations, and generate reports.

Assignment Activity 4: Database Design Methodologies

Effective database design requires following a systematic approach to model and implement databases. Students will explore database design methodologies such as the Entity-Relationship Model (ERM), Database Development Life Cycle (DBLC), and Agile Database Development. They will understand the importance of requirements analysis, conceptual modeling, logical design, and physical implementation in database development.

Assignment Activity 5: Normalization and Data Integrity

Normalization is a critical process in database design aimed at eliminating data redundancy and ensuring data integrity. Students will learn about different normal forms, from First Normal Form (1NF) to Boyce-Codd Normal Form (BCNF), and understand how normalization reduces data anomalies such as insertion, update, and deletion anomalies. They will apply normalization techniques to optimize database structures.

Assignment Activity 6: Database Management Systems (DBMS)

Database Management Systems (DBMS) are software applications that enable users to interact with databases. Students will explore different types of DBMS, including relational, object-oriented, and NoSQL databases. They will learn about popular DBMS platforms such as Oracle, MySQL, SQL Server, and MongoDB, and understand their features, capabilities, and use cases.

Assignment Activity 7: Database Security and Administration

Database security is paramount to protect sensitive data from unauthorized access, manipulation, and theft. Students will learn about security measures such as user authentication, access control, encryption, and auditing. They will understand the role of database administrators (DBAs) in managing and maintaining databases, including backup and recovery procedures, performance tuning, and capacity planning.

Assignment Activity 8: Data Warehousing and Business Intelligence

Data warehousing and business intelligence (BI) enable organizations to analyze and derive insights from large volumes of data. Students will explore the concepts of data warehousing, data mining, OLAP (Online Analytical Processing), and data visualization. They will understand how BI tools such as Tableau, Power BI, and QlikView are used to create interactive dashboards and reports for decision-making.
