1) complexity is more compared to centralized DBMS
2) It is much more expensive to setup and maintain a DDBMS. More hardware is required the network maintenance is increased the communication costs increase and there will be additional labour costs.
3) It is much more difficult to maintain a secure network system across multiple locations. The network needs to be made secure and access to replicated data needs to be maintained across multiple sites.
4)Integrity control is more difficult
5)Lack of standard
6)lack of experience
7)more complex database design

Some disadvantages of a distributed database management system (DDBMS) include increased complexity in data management, higher costs for implementation and maintenance due to the need for specialized hardware and software, and potential security risks associated with data transmission over networks. Additionally, ensuring consistency and coordination among distributed nodes can be challenging.

What is the difference between ddbms and parallel dbms?
A distributed database management system (DDBMS) manages databases that are stored on multiple computers, often in different locations. A parallel database management system (parallel DBMS) uses multiple processors to perform operations on a single database, improving performance by dividing tasks among these processors. In essence, DDBMS focuses on data distribution and replication across different sites, while parallel DBMS focuses on high-speed data processing using multiple processors.
What are the advantages and disadvantages of a DDBMS?
Advantages of a Distributed Database Management System (DDBMS): Enhanced availability and reliability: Data can be distributed across multiple locations for improved fault tolerance. Improved performance: Queries can be processed in parallel on multiple nodes, leading to faster response times. Scalability: DDBMS can easily scale by adding more nodes to the network. Disadvantages of a DDBMS: Increased complexity: Managing distributed data adds complexity to system design and administration. Data consistency challenges: Ensuring data consistency across distributed nodes can be complex and require careful coordination. Security risks: Distributed systems are more susceptible to security breaches and require robust security measures.
What are the disadvantages of informal learning?
Disadvantages of informal learning include lack of structure, potential for misinformation or inaccuracies, and limited opportunities for validation or recognition of learning achievements.
What are advantages and disadvantages of private warehouses?
Advantages of private warehouses include complete control over operations, security of goods, and flexibility in customization. Disadvantages may include high initial investment costs, ongoing maintenance expenses, and potential underutilization of space during off-peak periods.
Disadvantages of MIS?
Some disadvantages of Management Information Systems (MIS) include high initial setup costs, potential for data security breaches, and the need for ongoing maintenance and upgrades, which can be resource-intensive. Additionally, MIS may lead to information overload if not managed effectively, impacting decision-making processes.
What are the component of DDBMS?
The components of a Disributed DataBase Management System (DDBMS) are the Database Manager, the User Interface Request, and a Distributed Transaction Manager.

What is the full form of ACID according to computer architecture?
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.
What are function of DDBMS?
Except DDBM to have the funcationality of DBMS. It also has the folliwing funcationalities: 1. Extended Communication Services. 2. Extended Data Dictionary. 3. Distributed Query Processing. 4. Extended Concurrency Control. 5. Extended Recovery Services.
