A method and apparatus enables partitioning of data to efficiently store and retrieve data relating to a database system (either a parallel or non-parallel database system). Such partitioning may be performed by receiving information associated with at least one characteristic of the data and performing an algorithm to divide the data into related data segments. The data segments may be stored in a distributive database system based on the characteristic associated with the data. |

DETAILED DESCRIPTION In the following description, numerous details are set forth to provide an understanding of the present invention.
However, it will be understood by those skilled in the art that the present invention may be practiced without these details and that numerous variations or modifications from the described embodiments may be possible.
Generally, when data is transmitted from one system to another, such as from a server system to a client system, a certain amount of efficiency in retrieving the data is desired.
Often, a database may be accessed by a plurality of users or one user may issue a plurality of queries.
Allowing for more efficient access of data from a database can ease the computing congestion that occurs when multiple queries are being processed.
One way to improve performance in extracting data from a database is to set up a database such that data is distributed across a plurality of servers, called data servers (e.
g.
a distributive database system).
Partitioning data stored in the database in an efficient manner will improve the utilization of data servers in accessing data in the database.
An embodiment that provides a method and an apparatus for partitioning related data and storing them such that a minimum number of data servers are invoked, is provided below.
FIG.
1 illustrates a data communication system, which includes a database controller 110 coupled to a database system 120 and a client system 130.
The client system 130 can be coupled to the database controller 110 through a server 185 or alternatively, the client system 130 can be coupled directly to the database system 110.
In one embodiment, the client system 130 is a remote device.
In the illustrated embodiment, the server 185 receives requests from a client, such as Structured Query Language (SQL) queries, to extract data from the database system 120.
The client system 130 is coupled to the server 185 over a network connection 145.
The network connection 145 is typically either a private network connection or a public network connection, or a combination of both
