A Lump-sum Update Method as Transaction in MongoDB

Along with the progress of the cloud computing, it became necessary to deal with various and large quantity data in the distributed database environments. So, the various NoSQL databases have been proposed and put to practical use. However, as for the NoSQL databases, since it supports the distributed environment, the integrity of the database update is basically guaranteed only by the object unit. Therefore, there are serious restrictions to update the plural objects as a transaction. On the other hand, it is often necessary to perform the lump-sum or long-time update as a transaction in business systems. In this paper, we propose a method to update plural objects in a lump-sum as a transaction in MongoDB, which is a kind of the NoSQL database. Furthermore, through the evaluations by a prototype, we confirmed that the lump-sum update can be executed as a transaction without the latency of the concurrent object unit update.
