- in ths type system all the computation are distributed among several processors. distributted system are also reffered as loosely coupled system because here the processors do not share memory or a clock . instead each has is own local memory. its sharing the resource.
- Realibity:- it means in distributed system, if one site fails reamaining sites will share the work of failed site.
- Communication- when many sites are connected to one another by a communication network, the process at different sites have athe opportunity to exchange information. a user may intiate file transfer file or communicate.

There are several reasons for building distributed database systems. Firstly, distributing data across multiple nodes allows for better scalability and improved performance as the workload is distributed. Secondly, it enhances fault tolerance and reliability as data is replicated across multiple nodes. Finally, distributed database systems can provide better availability as accessing data from multiple nodes allows for load balancing and redundancy.

Why fragmentation and date replication are useful in Distributed DBMS?
Fragmentation and data replication are useful in Distributed DBMS for various reasons. Fragmentation helps in breaking a large database into smaller fragments that can be stored on different nodes, improving data access and query processing speed. It also enables data distribution and parallel processing, which can enhance overall system performance. Data replication, on the other hand, involves creating multiple copies of data on different nodes. This ensures data availability and fault tolerance, as if one copy becomes unavailable, the system can retrieve data from other replicas. It also enables load balancing and improves data accessibility in a distributed environment.
When a user is searching for an SSN from the personnel database they cannot search by?
When a user is searching for an SSN from the personnel database, they cannot search by the full SSN for security and privacy reasons. Instead, they may use a partial SSN or other identifier to search and retrieve the necessary information. Organizations typically restrict access to full SSNs to protect sensitive personal information.
Why are attributes of tables in a database often accessed together?
Attributes of tables in a database are often accessed together in queries because they are typically related and form part of the same record or entity. Accessing related attributes together in a query allows for more efficient and meaningful data retrieval and analysis. It also helps in maintaining data integrity and consistency within the database.

How do you identify key supporting terms?
Key supporting terms can be identified by looking for words or phrases that provide additional information or context to the main topic. These terms often help to explain or clarify the main idea and can include examples, definitions, reasons, or evidence that support the central concept.
