If customers require a slightly different data structure or have location specific requirements, the implementation is easy because the changes are minimal.

Data quality — Access to the data is controlled through the data services, which tends to improve data quality, as there is a single point for updates. Once those services are tested thoroughly, they only need to be regression tested, if they remain unchanged for the next deployment.

Pricing models[ edit ] There are hundreds of DaaS vendors on the Web, and the pricing models by which they charge their customers fall mainly into two major categories. This is the simplest model to implement. The vendors charge their customers based on the amount of data they want to use.

Specific to the DaaS model, a common criticism is that when compared to traditional data delivery, the consumer is really just "renting" the data, using it to produce a graph, chart or map, or possibly perform analysis, but for data as a service, generally the data is not available for download.If you are planning to use Oracle Application Server 10g and choose the Advanced option, ensure that you specify the location of your Oracle_Home..
