Any web server can offer a front-end web application, but it is run on the user's PC (a smartphone, tablet, or laptop), not the remote web server. A front-end web application is typically, but not always, a single-user application that is not shared with other users.
The focus of the book is general information management concepts and techniques concerning:
- integrity constraints and data validation,
- enumerations and enumeration attributes
- unidirectional and bidirectional associations between object types,
- subtyping and inheritance in class hierarchies.
