What is a Database?
Before discussing different mobile databases , let’s first look at what a database is. In the computing world, a database is a structured collection of data that is organized and stored in such a way that it enables efficient data retrieval, manipulation, and management . For modern applications, databases are the backbone that provides reliable and scalable data access and storage.
A database can be categorized into two main types
1. Local database
As its name suggests, the local database resides locally on the device where an application is installed or running . With a local database, users can store data without the need for any network connectivity. The local database is used in mobile applications to store user preferences, cached data, or user-specific data. Since data is stored locally, it stores and retrieves data quickly.
2. Remote database
A remote database is a database that stores data on remote servers and requires network connectivity , such as the Internet . Unlike local databases, data stored in a remote database can be accessed from multiple devices, which gives users the ability to access data from anywhere. The remote database follows the client-server architecture , where applications run on client devices and communicate with the data server to perform data operations.
Importance of Database in Mobile App Development
A well-chosen database forms the backbone of a robust and efficient mobile application. It empowers developers to:
- Store and Manage Data Effectively: Organize large amounts of data in a structured and easily retrievable manner.
- Enhance Performance: Ensure fast data access and manipulation, leading to a smooth user experience.
- Enable Scalability: Accommodate application growth as the user base and data volume increase.
- Facilitate Offline Functionality: Allow users to access and interact with the application even without an internet connection (depending on the database).
- Strengthen Security: Implement robust security measures to protect sensitive user data.
