PROBLEM TO BE SOLVED: To provide a database operation device, a database operation method and a program, allowing execution of operation without requesting description of SQL (Structured Query Language) from a user side when setting two or more related tables as operation targets, and allowing suppression of deterioration of access performance at that time. SOLUTION: The database operation device 1 includes: an entity object 12 created in each table 17; and an SQL generation part 14 generating an SQL sentence. The entity object 12 includes: information for specifying the table; an operation condition; and information for specifying the related table. The SQL generation part 14 generates the SQL sentence for executing operation to the table 17 according to the operation condition, and the entity object 12 also generates the SQL sentence for executing operation to the related table 17 when the entity object 12 includes the information for specifying the related table 17.
