  6. Challenge • Research project: there will be one group research project. Students must present the related work and their results to the class in the last lectures of the semester. • Homework assignments. There will be several homework exercises and reading for the lectures. • Tests: there will be two tests covering the course materials. Both tests are open book, in-class tests. CSCE 824

  7. Grading • Research project: 35%, Test 1 : 20%, Test 2: 25%, Homework assignment: 20% • 90 < A; 87 < B+ <= 90; 80 < B <= 87; 76 < C+ <=80; 65 < C <= 76; 60 < D+ <= 65; 50 <D <= 60 CSCE 824

  8. Topics Covered • Weeks 1-5: Distributed and Non-traditional Databases • Weeks 6-11: Database Security • Weeks 12-15: Student Presentations CSCE 824

  19. Questions? CSCE 824

  20. Database Management System (DBMS) • Collection of • interrelated data and • set of programs to access the data • Convenient and efficient processing of data • Database Application Software CSCE 824

  21. Evolution of Database Systems • Early days: customized applications built on top of file systems • Drawbacks of using file systems to store data: • Data redundancy and inconsistency • Difficulty in accessing data • Atomicity of updates • Concurrency control • Security • Data isolation — multiple files and formats • Integrity problems CSCE 824

  22. Abstraction • View level: different perspectives • Application programs hide irrelevant data • Logical level: data models • Logical representation of data • Different approaches: hierarchical, network, object oriented, semi-structured, etc. • Data independence principle • Physical level: how data is stored CSCE 824

  23. Data Models • A collection of tools for describing • Data • Relationships among data items • Semantics of stored data • Database constraints CSCE 824

  24. Database Management Systems • Smaller and smaller systems • Past: large and expensive DBMS • Present: DBMS in most personal computers • More and more data stored – BIG DATA • Past: few MB • Present: terabyte (1012 bytes), petabyte (1015 bytes) • Functionality: from physical to view level • Optimization CSCE 824

  25. Data Definition Language (DDL) • Defines the database schema and constraints • DDL compiler data dictionary • Metadata – data about data CSCE 824

  26. Data Manipulation Language (DML) • Accessing and manipulating the data • Query Languages • Procedural – user specifies what data is required and how to get those data • Nonprocedural – user specifies what data is required without specifying how to get those data CSCE 824

  27. Current Demands • Efficient data processing of large data sets • Long running transactions • Real-time demand • Usability for specific applications • … CSCE 824

  28. Data Security

  29. Security Objectives • Confidentiality: prevent/detect/deter improper disclosure of information • Integrity: prevent/detect/deter improper modification of information • Availability: prevent/detect/deter improper denial of access to services CSCE 824

  30. Security Threats • Poor design • Insufficient quality control • Accidents • Attacks CSCE 824

  31. Achieving Security • Policy • What to protect? • Mechanism • How to protect? • Assurance • How good is the protection? CSCE 824

  32. Database Security • Security Policy • Access control models • Inference control • Integrity protection • Privacy problems • Fault tolerance and recovery • Auditing and intrusion detection • TOOLS CSCE 824

  33. Next Class Relational data model CSCE 824
