Chapter 25: Problem 3

What are the main software modules of a DDBMS? Discuss the main functions of each of these modules in the context of the client-server architecture.

Short Answer

Expert verified
The main software modules of a DDBMS are: DDBMS Software, Data Communications Software, Application Software, and Network Software & Hardware. These have various roles in the context of client-server architecture: managing the database and processes, ensuring data integrity and consistency, providing interfaces for interaction and data processing, and facilitating communication respectively.

Step by step solution

01

Introduction to DDBMS

A Distributed Database Management System (DDBMS) governs and manages the distribution of data physically across multiple locations. In essence, it allows access to data from a network of computers as if it was in a single location.
02

Software Modules of DDBMS

The primary modules of a DDBMS include the following: \n1. DDBMS Software: To manage the database over a distributed network.\n2. Data Communications Software: To ensure data integrity and consistency over the network.\n3. Application Software: To provide interfaces for users and applications to interact with the system.\n4. Network Software & Hardware: To facilitate communication channels for data transmission.
03

Functionalities in Client-Server Architecture

In the context of client-server architecture, each module has a specific role:\n1. DDBMS Software: Controls the data distribution and manages processes like query processing, transaction management, and concurrent control on the server side.\n2. Data Communications Software: Ensures data integrity and consistency across all client nodes and servers.\n3. Application Software: On the client side, they provide users and applications with interfaces for data interaction and processing.\n4. Network Software & Hardware: Establishes a network for effective communication between the client and the server.

Conclusion

Understanding the key modules of a DDBMS and their functions helps in the effective design, implementation, and management of distributed databases, especially in the context of a client-server architecture.

, Primary_author, Topic, Tota7_stock, \$price) BOOKSTORE (Store#, City, State, Zip, Inventory_value) STOCK (Store#, Book#,… # Consider the following relations: BOOKS (Book#, Primary_author, Topic, Tota7_stock, \$price) BOOKSTORE (Store#, City, State, Zip, Inventory_value) STOCK (Store#, Book#, Qty) Total_STock is the total number of books in stock, and INVENTORY_VALUE is the total inventory value for the store in dollars. a. Give an example of two simple predicates that would be meaningful for the BOOKSTORE relation for horizontal partitioning. b. How would a derived horizontal partitioning of stock be defined based on the partitioning of BOOKSTORE? c. Show predicates by which Books may be horizontally partitioned by topic. d. Show how the stock may be further partitioned from the partitions in (b) by adding the predicates in \((\mathrm{c})\)

What are the main reasons for and potential advantages of distributed databases?

How is a horizontal partitioning of a relation specified? How can a relation be put back together from a complete horizontal partitioning?

Discuss what is meant by the following terms: degree of homogeneity of a DDBMS, degree of local autonomy of a DDBMS, federated DBMS, distribution transparency, fragmentation transparency, replication transparency, multidatabase system.
