why we need database and explain characteristics of the database in short in pointwise.

Efficient storage and retrieval: Databases provide a structured and organized way to store and retrieve large amounts of data quickly and efficiently. This is important for businesses that deal with a vast amount of data on a daily basis.

Data integrity: With a database, data can be stored in a secure and consistent manner, ensuring that it is free from errors and duplication. This helps in maintaining the accuracy and reliability of the data.

Data sharing: Databases allow multiple users to access and manipulate the same data at the same time. This makes collaboration and data sharing easier among different departments or teams within an organization.

Data security: Databases provide security features to protect sensitive information from unauthorized access. This helps in safeguarding the data from potential cyber threats.

Data backup and recovery: Databases often have built-in backup and recovery features, which help in the event of data loss or corruption. This ensures that critical data is not permanently lost.

Scalability: Databases can handle large amounts of data and can be easily scaled up to accommodate the growing needs of an organization. This is especially important for businesses with evolving data requirements.

Flexibility: Databases provide flexibility in terms of data storage, retrieval, and manipulation. This allows for the customization of databases based on the specific needs and requirements of an organization.

Data consistency: Databases enforce rules and relational integrity constraints, ensuring that data is consistent and accurate. This is important for maintaining the overall quality of data.

Improved decision making: Databases provide the tools and capabilities to analyze and report on data, which helps in making informed and data-driven decisions.

Data independence: Databases allow for the separation of data from the applications that use it, providing a level of independence and flexibility for both the data and the applications.
