The relationships between database applications DBMS and databases is as follows:
Databases can be simple or complex. simple databases can be kept in a Microsoft Excel spreadsheet or they can be maintained in a user generated Microsoft Access database which can be programmed to query certain data that has been entered into that database over a period of time. Microsoft Excel and Microsoft Access are also applications that are used to build databases that can be incorporated into DBMS or Database Management Systems. These systems can be extremely complex or they can be simple meaning that maintenance to these systems is not demanding. If the DBMS is complex it may require an entire team of technicians and in some cases engineers.The relationship between users, database applications, databases, and Database Management Systems can be simplified even further - Users can access a database that has been created with a database application to query managed data that is a part of a uniform Database management system.

What is the differences between naive end user and stand alone end user?
Naïve (or Parametric) end-users are the largest section of end-user population , they Use previously implemented and tested programs (called "canned transactions") to access/update the database .Stand-alone end-users Mostly maintain personal databases using ready-to-use packaged applications.
WHAT TASKS does dbms do?
A Database Management System or DBMS provides the interface between users and a database. Some of its tasks include: data integrity, security, recovery of data, support concurrent updates and update data.
What Four main types of actions involved in database?
A database management system is a collection of programs that enables users to create and maintain a database. The DBMS is general purpose software that facilitates the processes of Defining, Constructing, Manipulating and Sharing data among various users and applications.Defining a database involves specifying the data type, structure, and constraints of the data to be stored in the database. The database definition or descriptive data information is also stored in the database in the form of a database catalog or dictionary; it is called meta-data.Constructing the database is the process of storing the data on some storage medium that is controlled by the DBMS.Manipulating a database includes functions such as querying the database to retrieve specific data, updating the database to reflect changes in the miniworld, and generating reports from the data.Sharing a database allows multiple users and programs to access the database simultaneously.
What is a database accessible by many users on different computers known as?
multy-access
When users modify data in a database using the database approach they must make changes to all files instead of just one file?
False
Why is a database considered to be self-describing?
A database is considered self-describing because it contains metadata that describes its structure and organization. This metadata includes information about the tables, columns, data types, relationships, and other properties of the database. This allows users and applications to understand and interact with the database without needing external documentation.
What is the difference between a personal database system and a enterprise class database system?
A personal database system allows users to store their own files and interact with other applications. An enterprise class database system allows enterprises to analyze their own data.
When is a database used?
A Database is a organized collection of inter-connected data items. It is a collection of persistent data (or information). You need Database when you want to share data of all kinds between users, between tools working on them, between computers. Either it might be a different users or other applications, everyone can access the same set of Data. We need a reliable storage system which can guarantee the health of Data. Several users/applications must be able to safely access the same data concurrently. You can use large amount of data efficiently. there are many more reasons Security, protection, we can restrict the users to certain levels, etc.
List the different types of database user and explain?
4 Types of Database Users Users are differentiated by the way they expect to interact with the system: · Application programmers - interact with system through DML calls. · Sophisticated users - form requests in a database query language. · Specialized users - write specialized database applications that do not fit into the traditional data processing framework. · Naive users - invoke one of the permanent application programs that have been written previously.FROM: Database Systems Concepts 1.17 Silberschatz, Korth and Sudarshan c1997
Is dbms a system software or application softwatre and why?
A DBMS is a database management software, which is an application. System software is for controlling a computer, whereas applications are what users use to do things on a computer. Windows is systems software. A database is an application. Computer users use databases to manage their data, so it is a task that a user wants to do on a computer.A DBMS is a database management software, which is an application.

What is a centralised database?
A centralised database is a single database under the control of a single Database Management System. All users and client applications connect directly to the DBMS. This means that the database is stored in only one location and everyone in the system is directly connected to it. Unlike a distributeddatabase which is a set of connected databases stored on multiple computers that appears to users as a single database.
What is mdbms?
A multidimensional database management system is a database management system that uses a data cube as an idea to represent multiple dimensions of data available to users. This database is optimized for data warehouse and analytical processing applications...
Where can you find a comparison between oracle snapshot replication and oracle streams replication?
The process of creating and managing duplicate versions of a database. Replication not only copies a database but also synchronizes a set of replicas so that changes made to one replica are reflected in all the others. The beauty of replication is that it enables many users to work with their own local copy of a database but have the database updated as if they were working on a single, centralized database. For database applications where users are geographically widely distributed, replication is often the most efficient method of database access.
What database is an efficient way to share information because it?
A relational database such as MySQL or PostgreSQL is an efficient way to share information because it allows users to organize data in structured tables with defined relationships. These databases are designed for easy querying, indexing, and scaling, making it efficient to access and share data among multiple users or applications. Additionally, they offer functionality for data integrity and security measures to control access and maintain consistency.
Define various types of database users?
There are following types of users: § Database Administrators § Security Officers § Network Administrators § Application Developers § Application Administrators § Database Users
What is the difference between centralize and decentralize database?
A centralized database contains all the data tables in one place which all users access. A decentralized database creates copies of the database design in different areas and any given copy contains only that data which is relevant to its particular users.
What is data replication?
The process of creating and managing duplicate versions of a database. Replication not only copies a database but also synchronizes a set of replicasso that changes made to one replica are reflected in all the others. The beauty of replication is that it enables many users to work with their own local copy of a database but have the database updated as if they were working on a single, centralized database.For database applications where users are geographically widely distributed, replication is often the most efficient method of database access.
