A data storage and management apparatus for storing and managing data of an object as a persistent object in a data storing system. When storing an object in the data storing system, information on complexity of data of at least one attribute of the object is recorded in the apparatus, and data of each of the at least one attribute of the object is stored in a first table in the data storing system when the data of the attribute is not complex data, and in a second table in the data storing system when the data of the attribute is complex data. When manipulating data of an attribute of the object in the data storing system, the above information on complexity is referred to, and manipulation is performed on the first table when the data of the attribute is not complex data, and on the second table when the data of the attribute is complex data.
