create the database
DBMS stands for DataBase Management System. The main concepts are the structure, the manipulation, and a set of integrity rules.
There are generally three main types of database system users: database administrators (DBAs), who manage and maintain the database; application developers, who create applications that interact with the database; and end-users, who utilize the applications to access and manipulate data. Each user group has distinct roles and responsibilities, contributing to the overall functionality and management of the database system.
The main objective of MIS is to improve the management decision making, by providing accurate and up-to date information about the key aspects of organisational performance.
Functions of a Database Management System: - Database Definition - Database creation (storing data in a defined database) - Retrieval (query and reporting) - Update(Changing the contents of the database) - Programming User Facilities for system development) - Database revision and restructuring - Database integrity control - Performance Monitoring
There are four basic and main database management systems that are used today. Those four include hierarchical, network, relational and object-oriented.
The main objectives of a database include data storage, retrieval, and management, ensuring that data is organized and accessible. Databases aim to maintain data integrity and consistency while supporting concurrent access by multiple users. Additionally, they facilitate efficient data manipulation and analysis, enabling users to generate meaningful insights and reports. Overall, databases are designed to optimize data handling and support decision-making processes.
To manage and review
A "query" is usually a programmatic statement that is understand by a DBMS(Database management system) that understands how to access and manipulate data within a database. The primary operations of a query are referred to as CRUD(Create, Read, Update, Delete) and the main programming language for writing queries is ANSI SQL.
