There is not a lot of difference between DDBMS and parallel DDBMS. Both systems store data over several sites, and parallel DDBMS uses parallelization over certain operations.
A DBMS (Database Management System) is a software that manages databases and provides functionalities to store, retrieve, and update data. An RDBMS (Relational Database Management System) is a type of DBMS that stores data in a structured way using tables with relationships between them. RDBMS enforces the relational model, which allows for data integrity through constraints and supports SQL for querying data.
The advantages of parallel DBMS include improved performance and scalability, as it allows for parallel processing of queries across multiple servers or processors. This can result in faster query execution and the ability to handle larger data volumes. However, the disadvantages include increased complexity and cost of implementation, as well as the need for specialized hardware and software to support parallel processing. Additionally, parallel DBMS may require additional effort for administration and maintenance.
A flat file is a simple file containing data without any structured format, while a Database Management System (DBMS) is a software system that manages databases by organizing, storing, and retrieving data. A DBMS allows for more organized and efficient data management, supports relationships between data, and provides features like security and data integrity that are not available with flat files.

Actually ACID is the combination of the 1# letters of the properties that DDBMS (Distributed - DBMS) possesses. A - Atomicity C - Consistency I - Isolation D - Durability This four property defines the architecture of DDBMS.

difference between relation sehema and relation instance in dbms
A Distributed Database Management System (DDBMS) offers several additional functions over a centralized DBMS, including data distribution across multiple locations, which enhances data availability and reliability. It enables data replication and fragmentation for improved performance and fault tolerance. Additionally, a DDBMS supports data transparency, allowing users to access and manipulate data without needing to know its physical location, and provides mechanisms for distributed transactions to ensure consistency across the network.
A homogeneous Distributed Database Management System (DDBMS) uses a single DBMS product to manage the databases spread across multiple locations in a network. The data model, query language, and transaction management are consistent across all nodes, streamlining operations and ensuring data consistency. This approach simplifies administration and maintenance as all nodes are governed by the same DBMS software.

Traditional FPS and DBMS both are different from each other. In DBMS there is security of data as well as integrated data while this is not in FPS.
A Homogeneous database will have only one DBMS, while heterogeneous databases have multiple DBMS's
A DBMS is a database management system. A database application would be something inside the DBMS such as: ~a way to search files ~a way to pull certain information
