What Are Data Systems?

Data systems are the infrastructure which captures, stores and allows access to data that businesses use. They can comprise the database management system (DBMS) as well as data warehouses, specialized data platforms like NoSQL databases and alternative storage methods for data such as file systems and cloud object storage services. They also can include master-data management, which creates an organization’s common set of reference information for its clients, products and other assets.

Volume as well as variety and speed are the primary aspects of a good data management system. Volume refers to the amount of data being processed, usually in large and complex data sets that can’t be handled by a single computer. Variety refers specifically to different kinds of data that are being gathered from traditional sensors and feeds from social media and other sources. Velocity is the speed with which data flowing into and out of the data system.

These four traits have prompted the development of new and innovative data systems. There are new data platforms which can handle a wide range of data. These platforms are in addition to traditional databases.

A large sensor data systems, for example is a networked system comprising devices and sensors that collect a vast variety of information from physical sensors like smartphones or wearable medical sensors. The readings from sensors can contain location, signal or image data, along with timestamps. The data is saved on the device and then transmitted to a server. The data then undergoes preprocessing to ensure that the resulting data is clean and meaningful to be processed and analysed.
