In a web application, data is typically stored in the server or in the cloud. This is because web apps do not need to be downloaded and they are accessed over a network.
A secure website safeguards transmitted information by using “Encryption,” which codes the data as it is sent over a network, so that it is only readable after decryption. Google, for example, uses this method to protect the privacy of its users.
Client-side storage allows a website to store different types of data on a user’s device. This can be used to save a site or document for offline use, keep user-specific settings on a website, and more.
There are various ways to persist data, including session storage, local storage, cookies, webSQL, cache and indexedDB. Firebase offers a suite of real time database services that can help you store and synchronize your data across multiple clients.
Structured data is commonly stored in tabular form and managed in a relational database. This type of data is easy to manage and is highly searchable, both by humans and by machines.
Unstructured data is a term that encompasses data that is not organized into tables or rows, such as documents, emails, video, audio files and social media posts. These data items can be hard to standardize and categorize, making them more difficult for tools that handle structured data to parse.
Unstructured data is often used in business applications and has more flexibility than structured data because it can be processed in a variety of ways. For instance, it can be used to track the activities of a company’s employees or a customer’s interactions with the company.
