White sugar White sugar White sugar, also called table sugar, granulated sugar or regular sugar, is the sugar commonly used in North America and Europe, made either of beet sugar or cane sugar, which has undergone a refining process. The refining completely removes the molasses and makes the white sugar actually sucrose (with a purity higher than 99.7%), whose molecular formula is CHO. The origin of the sugar thus produced is therefore chemically indistinguishable (sugar cane or sugar beet): it's however possible to identify its origin through a carbon-13 analysis (similar to radiocarbon dating used in archeology). From a chemical and nutritional
Single Table Inheritance Single Table Inheritance Single table inheritance is a way to emulate object-oriented inheritance in a relational database. When mapping from a database table to an object in an object-oriented language, a field in the database identifies what class in the hierarchy the object belongs to. All fields of all the classes are stored in the same table, hence the name "Single Table Inheritance". In Ruby on Rails the field in the table called 'type' identifies the name of the class. In Hibernate (Java) and Entity Framework this pattern is called Table-Per-Class-Hierarchy and Table-Per-Hierarchy (TPH) respectively., and the column containing the
