Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. SchemaBank is a web-based data modeling and database design tool, delivering to users over the internet using the software as a service (SaaS) model. It supports visual creation of Entity-relationship diagram and conversion of such diagrams into Data Definition Language (e.g. SQL statements). Database design is the process of producing a detailed data model of a database. This logical data model contains all the needed logical and physical design choices and physical storage parameters needed to generate a design in a Data Definition Language, which can then be used to create a database. A fully attributed data model contains detailed attributes for each entity.
