Periodically, all the systems would backup and combine the data into a database where reports could be run and everyone could get insight into what was going on.The problem was that the database technology simply couldn’t handle multiple, continuous streams of data. It couldn’t handle the volume of data. It couldn’t modify the incoming data in real-time. And reporting tools were lacking that couldn’t handle anything but a relational query on the back-end. Big Data solutions offer cloud hosting, highly indexed and optimized data structures, automatic archival and extraction capabilities, and reporting interfaces have been designed to provide more accurate analyses that enable businesses to make better decisions.Better business decisions means that companies can reduce the risk of their decisions, and make better decisions that reduce costs and increase marketing and sales effectiveness.What Are the Benefits of Big Data?This infographic from Informatica walks through the risks and opportunities associated with leveraging big data in corporations.Big Data is Timely – A large percentage of each workday, knowledge workers spend attempting to find and manage data.Big Data is Accessible – Senior executives report that accessing the right data is difficult.Big Data is Holistic – Information is currently kept in silos within the organization.
