•Data redundancyDifferent systems/programs have separate copies of the same data
•Program-data dependence
All programs maintain metadata for each file they use
•Lack of flexibility
Programmers must design their own file formats
•Poor security, lack of data-sharing and availability
No centralized control of data
•Excessive Program Maintenance

A Traditional database environment is the one which allows the following: 1) Data integrity, 2) security 3) convenience 4) sharing

Managing SQL servers is performed by database administrators and/or database managers. The job entails managing large relational databases and ensuring proper security of the data.
data base means a collection of data,which may be inter related. data base management system is a collection of programs for managing the data base.
Data redundancy Lack of data redundancy Data inconsistency Data security
Traditional file environment is not well suited to save data in them. They make it difficult to read the data as they are more unstructed.

Managing data refers refers to tho the receipt, processing, retrieving and the storage of data.
A large distributed database presents several security problems, such as data breaches, unauthorized access, data leaks, and data inconsistency. Ensuring secure communication between nodes, access control, encryption, and regular security audits are essential to mitigate these risks. Additionally, managing user authentication, authorization, and ensuring compliance with data protection regulations become more complex in a distributed environment.

Melissa Data is a data management system. It is helpful if you are managing data, managing emails, and assessing overall datum being used by your computer.
SATA- serial ATA cable, these standards use a serial data path rather tha traditional data path. ( A+ Guide to managing and maintaining your pc, sixth edition, Jean Andrew.)
The data of a website like www is typically stored on a server, which is a powerful computer that hosts the website's files and delivers them to users when they access the site. These servers are usually housed in data centers that are designed to provide a secure and reliable environment for storing and managing website data.
DBMS is the integration of files and data called the database. It has a number of commercial uses like controlling data access, managing concurrency control, enforcing data integrity. In fact most of the things in the internet is run with the help of DBMS.
A DBMS solves the problems of the traditional file system by providing data independence, allowing easier data manipulation through SQL queries, ensuring data integrity through transaction control mechanisms, and offering robust security features to protect data from unauthorized access and modifications.
When resolving data requests in a distributed environment, it's important to consider data consistency, latency, network reliability, and load balancing. Ensuring that all nodes have consistent and up-to-date data, managing latency between different nodes, maintaining network reliability for data transmission, and distributing requests evenly to avoid overloading any specific node are key issues to address.
