Question

The purpose of this exercise is to successfully identify and describe in detail 3 database systems that you or someone you are close to encounters often for their normal day-to-day activities. When considering database systems to describe, consider the points listed below: 1. What is the database system identified? Remember to keep it broad (e.g. our accounting system) 2. Where would you typically see such a database system used? 3. Why does this database system exist? What problem is being solved? 4. How is this database system used? 5. Who is the primary user for this database system? I expect to see nothing less than a paragraph (3-4 sentences) about each system identified. You are all database professionals so I expect it to be written in a professional format.

Explanation / Answer

1) Digital Identification Database system is authorised collection of journal's Title & papers, books online Series, Serials, Conferences, Seminars, Special talks, Short Communications, Case Studied, Research notes, approved by DIDS body. A Digital Identification Database system (DIDS) is a unique anumeric string assigned by a registration agency (the International DIDS Group to identify content and provide a persistent ID to its location on the Internet. The publisher assigns a DIDS when your article is published and made available electronically
After reviewing and approving the quality, details of matter, Digital identification Database system provides unique DIDS (Digital Data Link) to each data.

A DBMS makes it possible for end users to create, read, update and delete data in a database. The DBMS essentially serves as an interface between the database and end users or application programs, ensuring that data is consistently organized and remains easily accessible.

The DBMS manages three important things: the data, the database engine that allows data to be accessed, locked and modified -- and the database schema, which defines the database’s logical structure. These three foundational elements help provide concurrency, security, data integrity and uniform administration procedures. Typical database administration tasks supported by the DBMS include change management, performance monitoring/tuning and backup and recovery. Many database management systems are also responsible for automated rollbacks, restarts and recovery as well as the logging and auditing of activity.

The DBMS is perhaps most useful for providing a centralized view of data that can be accessed by multiple users, from multiple locations, in a controlled manner. A DBMS can limit what data the end user sees, as well as how that end user can view the data, providing many views of a single database schema. End users and software programs are free from having to understand where the data is physically located or on what type of storage media it resides because the DBMS handles all requests.

The DBMS can offer both logical and physical data independence. That means it can protect users and applications from needing to know where data is stored or having to be concerned about changes to the physical structure of data (storage and hardware). As long as programs use the application programming interface (API) for the database that is provided by the DBMS, developers won't have to modify programs just because changes have been made to the database.
