![]() A new data category can easily be added to a relational database without having to change the existing applications. Relational databases use SQL in their user and application program interfaces. These are indexed to make it easier to search using SQL or NoSQL queries. Information in a relational database about a specific customer is organized into rows, columns and tables. Each table has columns with at least one data category, and rows that have a certain data instance for the categories which are defined in the columns.

These early databases were network models where each record is related to many primary and secondary records. ![]() For example, personal cloud storage is available for individual users to store media, such as photos, in a managed cloud.ĭatabases were first created in the 1960s. Databases can also be used to store personal information. Healthcare providers use databases to securely store personal health data to inform and improve patient care. ![]() The data is used to recommend content to users and improve the user experience.
