Database Systems: Introduction to Databases and Data Warehouses Nenad Jukic

    Database systems are software applications that store, manage, and manipulate data for various purposes. Data can be organized in different ways, such as tables, graphs, documents, or multimedia files. Database systems provide users with tools to create, query, update, and analyze data, as well as to ensure its quality, security, and integrity.

    One of the main challenges of database systems is to handle the increasing volume, variety, and velocity of data in the modern world. Data can come from different sources, such as sensors, social media, web pages, or transactions. Data can also have different formats, such as structured, semi-structured, or unstructured. Data can also change rapidly and require real-time processing and analysis.
