Data storage space is virtually infinite in cloud computing. To store data in the cloud requires more cost because it is a 'Pay and use model' and also the resources are based on budget constraints. Normally, question performance is a very important concept in database management system. To improve that introduces novel approach which will reduce the cost of data storage within the cloud. This novel approach converts the given aggregated data into horizontal layout form, which will reduce the size of the data to store in the cloud. This paper presents the effective cost model for data storage with horizontal layout within the cloud.
