Advanced Concepts in ⥫ Distributed Database Management Re p l i c a t i o n , and Systems: Design Techniques Fragmentation, Introd uction to Distributed are essential f o r Databases managing data across multiple l o c a t i o n s. This presentation explores such as fragmentation, re p l i c a t i o n , and design techniques, which are c r u c i a l f o r enhancing and i n d i s t r i b u t e d environments. Understanding Fragmentation is the process o f d i v i d i n g a database i n t o smaller, manageable pieces. This technique enhances and reduces. There are three types of fragmentation: horizontal, v e r t i c a l , and h y b r i d , each serving d i ff e r e n t use cases. Horizontal Fragmentation Explained In , rows o f a r e l a t i o n are divided i n t o subsets based on c e r t a i n c r i t e r i a. This method optimizes and minimizes , making i t i d e a l f o r ap p l i c ati on s with d i s t i n c t user groups or geographical distribution. Ve r t i c a l Fragmentation Explained In , columns o f a re l a t i o n are s p l i t i n t o smaller subsets. This technique is b e n e fi c i a l for optimizing when s p e c i fi c a t t r i b u t e s are frequently accessed,allowing f o r and retrieval. Hybrid Fragmentation Techniques combinesboth horizontal and v e r t i c a l fragmentation, allowing for a t a i l o re d approach t o data d i s t r i b u t i o n. This method leverages the benefi ts o f both techniques, enhancing and in complex database systems. Importance of involves s t o r i n g copies o f data across m u l t i p l e s i t e s t o ensure and. I t plays a c r i t i c a l r o l e i n Replication d i s t r i b u t e d systems by providing data redundancy and improving f o r users i n d i ff e r e n t l o c a t i o n s. Types o f Replication Strategies There are two primary : synchronous and asynchronous. Synchronous re p l i c a t i o n ensures immediate consistency across sites, while asynchronous re p l i c a t i o n o ff e r s improved at the cost o f potential data l a g. Design Techniques f o r DDBMS E ff e c t i v in e , DDBMS , include. and techniquesare c r u c i a l f o rThese optimizing the performance and ensuring that the system can handle e ffi c i e n t l y. Challenges i n D i st ri but ed Databases Despite t h e i r advantages, DDBMS face challenges such as , , and.
