Abstract
Data pages of a database may be shared to create a copy of the database. A request to create a copy of the database may be received. Pointers to the data pages in the data store may be generated and stored as part of the copy of the database. When a request to read a data page in the copy of the database is received, the pointer to the data page may be accessed and the data page read from the database. When a request to modify a data page in the copy of the database is received, a modified version of the data page may be stored as part of the copy of the database and the pointer updated to point to the modified version of the data page.
