Distributed and Object Oriented Database(DOOD) Syllabus

Course Description: This course aims to discuss concepts of distributed and object oriented database management systems. Main focus is given to basic concepts of DDBMS, distributed database design, distributed query processing, distributed concurrency control, concepts of OODBMS, and language and design of object oriented database.

Course Objectives:

    • Discuss basic concepts related to distribute DBMS.

    • Exemplify design of distributed database.

    • Describe distributed query processing and concurrency control.

    • Discuss basic concepts of OODBMS.

    • Demonstrate language and design for distributed database.

   Distributed Database. Distributed vs Centralized Database System; advantages

  and Application. Transparency, performance and reliability. Problem areas of

 Distributed Database. Integrity Constraints in Distributed Databases.

1.2 Distributed Database Architectures: DBMS standardization. Architectural

   models for Distributed DBMS – autonomy, distribution and heterogeneity.

2.1 Distributed Query Processing: Query Decomposition and Data localization for

   distributed data, join ordering, semi-join strategy, Distributed Query optimization

  methods.

2.2 Distributed Transaction Management: The concept and role of transaction.

   Properties of transactions-Atomicity, Consistency, Isolation and Durability.

  Architectural aspects of Distributed Transaction, Transaction Serialization.

2.3 DistributedConcurrency Control: Lock-based and Timestamp-based

 Concurrency Control methods. Optimistic method for Concurrency Control.

 Deadlock management- prevention, avoidance detection, and resolution. Non-

 serializable schedule and nested distributed transaction.

2.4 Reliability of Distributed DBMS and Recovery: Concept and measures of

reliability, Failure analysis, types of failures. Distributed Reliability Protocols.

Recovery techniques. Two Phase Commit , Presumed abort, Presumed commit.

Three phase commit, Partitions, Scalability of Replication.

3.1 Object Oriented Database Concept: Data types and Object, Evolution of Object

   Oriented Concepts, Characteristics of Object Oriented Data Model. Object

  Hierarchies - Generalization, Specialization, Aggregation. Object Schema. Inter-

 object Relationships, Similarities and difference between Object Oriented

Database model and Other Data models.

3.2 OODBMS Architecture Approach: The Extended Relational Model Approach.

   Semantic Database Approach, Object Oriented Programming Language Extension

  Approach, DBMS Generator Approach, the Object Definition Language and the

 Object Query Language.

3.3 The Object Oriented DBMS Architecture, Performance Issue in Object Oriented

   DBMS, Application Selection for Object Oriented DBMS, the Database Design

  for an Object Relational DBMS. The Structured Typed and ADTs, Object

 identity, Extending the ER Model ,Storage and Access Methods, Query

Processing Query Optimization, Data Access API(ODBC,DB Library,

DAO,ADO,JDBC,OLEDB), Distributed Computing Concept in COM, COBRA.

Students should implement all the concepts of object oriented and distributed databases mentioned in the course.
