What Is Big Data?
I want to explain to you that big data is stored electronically and analyzed using software specifically designed to handle complex data sets. The term 'big data' covers the volume of information, the speed at which it's created and collected, and the scope of the data to provide the raw material used in data mining. Technology companies like Alphabet and Meta use big data for tasks such as generating advertising revenue through targeted ads on social media platforms and websites.
Key Takeaways
You should know that big data can be either structured, often numeric and easily stored, or unstructured, which is free-form and less quantifiable. Data collection comes with the potential vulnerability to cyberattacks and data breaches. Consumer data provides companies with insight to match their products and marketing efforts to demand.
Big Data Collection and Storage
Big data is structured or unstructured. Structured data is commonly numeric information easily accessed from databases and spreadsheets. Unstructured data can be more qualitative and unorganized. According to IBM, examples of unstructured data may include text, mobile activity, social media posts, and Internet of Things (IoT) sensor data. Semi-structured data has characteristics of both structured and unstructured data.
Big data is collected through questionnaires, product purchases on websites or at point-of-sale (POS) terminals, electronic check-ins, personal devices, and apps. While beneficial for multiple uses, big data collection raises privacy concerns and the potential vulnerability to cyber attacks and data breaches.
Big data is typically stored electronically in what are sometimes referred to as data warehouses or data lakes. It is analyzed using software that handles large data sets. Many software-as-a-service (SaaS) companies specialize in managing this type of complex data.
Fast Fact
Data mining is a process that analyzes relevant trends and patterns, transforming big data into useful information.
How Is Big Data Used?
The 'V's of Big Data' help define how this type of information differs from other data. Big data is a large volume of information collected quickly with high velocity. It consists of a variety of reliable information with proven veracity and provides value to corporate entities.
Data analysts find relationships in consumer data, such as demographics or purchase history, to determine whether a correlation exists. Companies rely on big data assessments to implement strategies in human resources, production, marketing, or sales. Big data helps increase the speed at which products get to market and reduces the time and resources required to gain market adoption. Big data helps target the right audiences and ensures customers come back. It allows companies to tailor products to deliver what customers want.
Important
The 'cloud' refers to networks of data servers where organizations or individuals can rent space to store large volumes of data. Cloud services such as Amazon Web Services, Microsoft's Azure, and Alphabet's Google Cloud are common choices.
What Is Predictive Analytics?
Predictive analytics refers to the collection and analysis of current and historical data to develop and refine models for forecasting future outcomes. Predictive analytics is widely used in business and finance as well as in fields such as weather forecasting, and it relies heavily on big data.
What Is a Data Warehouse vs. a Data Lake?
A data warehouse refers to the place where a business or other organization stores its big data for analysis. A data warehouse can reside in the owner's in-house servers, with an outside specialist company, or in the cloud, and is most commonly associated with structured data. A data lake is a term for repositories that accommodate structured, unstructured, and semi-structured data.
What Is the Role of Artificial Intelligence in Big Data?
Artificial intelligence can analyze big data. Big data can also be used to train artificial intelligence to make it more effective.
The Bottom Line
Big data is the vast, complex data sets that traditional data management systems cannot handle. Big data can help organizations create new strategies and make better corporate decisions when big data is collected and managed properly.
