Big Data

Pairview helps organisations to create a holistic information management strategy that includes and integrates many new types of data and data management alongside traditional data.

Making big data actionable and operational in the a business will provide new insights, ways of working, and higher performance, complement existing analytical technologies with new techniques and discovery tools.

Big data is defined by the four Vs:

Volume.

This is the amount of data. While volume indicates more data, it is the granular nature of the data that is unique. Big data requires processing high volumes of low-density, unstructured Hadoop data.

This is data of unknown value, such as Twitter data feeds, click streams on a web page and a mobile app, network traffic, sensor-enabled equipment capturing data at the speed of light, and many more. This data needs to be converted into valuable information. For some organisations, this might be tens of terabytes, for others it may be hundreds of petabytes.

Velocity.

This is the fast rate at which data is received and acted upon. The highest velocity data normally streams directly into memory versus being written to disk. Some Internet of Things (IoT) applications have health and safety ramifications that require real-time evaluation and action.

Other internet-enabled smart products operate in real time or near real time. For example, consumer e-Commerce applications seek to combine mobile device location and personal preferences to make time-sensitive marketing offers. Operationally, mobile application experiences have large user populations, increased network traffic, and the expectation for immediate response.

Variety.

This includes unstructured and semi-structured data types, such as text, audio, and video require additional processing to both derive meaning and the supporting metadata.

Once understood, unstructured data has many of the same requirements as structured data, such as summarisation, lineage, auditability, and privacy. Further complexity arises when data from a known source changes without notice. Frequent or real-time schema changes are an enormous burden for both transaction and analytical environments.

Value.

Data has intrinsic value, but it must be discovered. There are a range of quantitative and investigative techniques to derive value from data from discovering a consumer preference or sentiment, to making a relevant offer by location, or for identifying a piece of equipment that is about to fail. The technological breakthrough is that the cost of data storage and compute has exponentially decreased, thus providing an abundance of data from which statistical analysis on the entire data set versus previously only sample.

The technological breakthrough makes much more accurate and precise decisions possible. However, finding value also requires new discovery processes involving clever and insightful analysts, business users, and executives. The real big data challenge is a human one, which is learning to ask the right questions, recognising patterns, making informed assumptions, and predicting behavior.
