Abstract

A non-transitory computer-readable medium including a program, which when executed by a computer, causes the computer to execute a process including: referring to data-size information indicating size of data corresponding to a query for acquiring the data stored in a storage, the data-size information and the data being stored in the storage and the data-size information being associated with the data in the storage; specifying an amount of the data corresponding to the query in accordance with the data-size information; and determining whether allows an output of the data corresponding to the query in accordance with the specified amount of the data and a data amount acceptable for the storage.

Claims

1. A non-transitory computer-readable medium including a program, which when executed by a computer, causes the computer to execute a process, the process comprising:

referring to data-size information indicating size of data corresponding to a query for acquiring the data stored in a storage, the data-size information and the data being stored in the storage and the data-size information being associated with the data in the storage;

specifying an amount of the data corresponding to the query in accordance with the data-size information; and

determining whether allows an output of the data corresponding to the query in accordance with the specified amount of the data and a data amount acceptable for the storage.

2. The non-transitory computer-readable medium of claim 1, wherein the process comprising:

acquiring the data corresponding to the query when it is determined that the output of the data corresponding the query is allowed.

3. The non-transitory computer-readable medium of claim 1 wherein

the data includes date items and the data-size information includes data item-size information each of which indicates sizes of each of the data items.

4. The non-transitory computer-readable medium of claim 1, wherein the process comprising:

notifying the specified amount of the data corresponding to the query.

5. The non-transitory computer-readable medium of claim 4, wherein the process comprising:

acquiring the data corresponding to the query when receives a output request; and

outputting the acquired data.

6. The non-transitory computer-readable medium of claim 1, wherein the process comprising:

setting a field to store the data-size information in a first table different from a second table including the data.

7. An apparatus comprising:

a memory; and

a processor coupled to the memory and configured to;

refer to data-size information indicating size of data corresponding to a query for acquiring the data stored in a storage, the data-size information and the data being stored in the storage and the data-size information being associated with the data in the storage;

specify an amount of the data corresponding to the query in accordance with the data-size information; and

determine whether allows an output of the data corresponding to the query in accordance with the specified amount of the data and a data amount acceptable for the storage.

8. A method comprising:

referring to data-size information indicating size of data corresponding to a query for acquiring the data stored in a storage, the data-size information and the data being stored in the storage and the data-size information being associated with the data in the storage;

specifying an amount of the data corresponding to the query in accordance with the data-size information; and

determining whether allows an output of the data corresponding to the query in accordance with the specified amount of the data and a data amount acceptable for the storage.
