Abstract: Described herein are techniques for compact representation of table columns via templatization. Column templates can model the collection of columns in a table as a logical entity. The logical entity can be split into two objects. A first object can contain a subset of column attributes (e.g., fields) that can be shared with other tables, such as name and data type. A second object can contain another subset of column attributes that are unique to a table, such as time stamps and created-on information.
