2. INTRODUCTION:
• What is Database?
• What is Database management system?

3. Distributed vs. Centralized
Centralized database can produce a bottleneck
Large volume of data input
Large database
Large volume of queries
In distributed databases, data consistency, replication, and
retrieval can be more problematic
Consistency of schemas
Retrieval in case the data location is not known
Communication overhead to ensure database consistency

4. ADVANTAGES:
• Controlling Redundancy
• Integrity can be enforced
• Inconsistency can be avoided
• Maintains privacy

5. DISADVANTAGES:
• Complexity
• Size
• Performance
• Cost

6. Hierarchical Structures
• Relationships between records form a hierarchy or treelike structure
• Relationship is one-to-many

7. Network Structure
• Many-to-many
• Data element can be accessed by following one of several paths

8. Relational Structure
• Stored in the form of two-dimensional tables
• Links various files to provide information

9. Relational Operations
• Select operation, to create a subset of records that meet a
states criterion
• Join operation, combines two or more tables
• Project operation, subset of columns

10. Object-oriented Structure
• Handles complex data like graphics, text, voice
• Supports inheritance
• Helps in creating product designs
