A service provider that enables data access on demand to users no matter their geographic location. Commonly also referred to as Data as a Service (DaaS), data services are similar to Software as a Service (SaaS) in that the information is stored in the cloud and is accessible by a wide range of systems and devices. Data services can eliminate redundancy and streamline costs by housing crucial data in one location, enabling the data to be accessed and/or updated by multiple users while ensuring a single point for updates. Potential drawbacks to data services include server downtime from the data service provider, data loss in the event of a disaster, and the security of the data, both in its stored location and in the transmission of the data among users. Data services where first used in web mash ups. However, nowadays it is used commercially and in such organisations as UN. The majority of companies have stored data in that way that it is readable to humans.
The result of the combined software/data consumer package and required EAI middleware has been an increased amount of software for organizations to manage and maintain, simply for the use of particular data. In addition to routine maintenance costs, a cascading amount of software updates are required as the format of the data changes. The existence of this situation contributes to the attractiveness of Data services to data consumers, because it allows for the separation of data cost and usage from that of a specific software or platform.
