Big data refers to a large volume of structured and unstructured data, which is rapidly generated and massive in size. With time, the amount of big data generated increases exponentially and is predicted to increase by two-thirds every year. Scala and Hadoop are two of the most widely used open-source frameworks for big data.
Big data analytics also requires programming languages. The Hadoop big data framework is written in Java. MapReduce apps can be written using Python, C++ or R.
Large data is collected through social media, search engines, service networks and public records. Businesses can also access other information sources to obtain big data.
For further analysis and processing, large datasets can be stored in either a semi-structured or structured database after they have been collected. NoSQL Databases can be used for big data storage because they are highly efficient in handling large amounts of data. As with any technology, big data has its benefits and disadvantages. There are some instances when big data’s benefits can be negated by its limitations in real-world situations.
Before using big data, companies need to be aware of both the pros and cons. Let’s now discuss the advantages and drawbacks of Big Data. Big Data’s Advantages
1. Big Data can help you make better decisions.
Companies are using big data to enhance their B2B marketing, communication, and advertising.
Big data is being used by many businesses, including those in travel, finance and real estate. Big data provides more data in an easily accessible format that businesses can use to accurately decide what customers want and how they behave.
By providing advanced analytics and business intelligence, big data helps to facilitate decision making. A business can get a better understanding of its customers if it has more data.
Analytics based on data reveal trends in business behavior and help companies expand their market share by optimising decision-making. These insights allow businesses to develop more targeted products, services and strategies and to run better campaigns that are competitive within their sector.
2. Lower costs for business processes.
Surveys conducted by New Vantage (now Precisely), reveal that big data analytics has greatly helped companies to cut their expenses. 66.7% Of New Vantage survey respondents claimed they use big data to cut expenses. 59.4% also claimed big data tools have helped them to reduce expenses and improve operational efficiency. Did you know that big data analytics tools such as Hadoop and Cloud-Based Analytics can reduce the cost of storing large data?
3. Fraud Detection
Financial firms, especially, are able to use large data sets to identify fraud. Machine learning algorithms and artificial Intelligence are used by data analysts to identify anomalies and patterns in transaction patterns. Anomalies in transaction patterns can indicate if something is not right or wrong, giving rise to suspicions of fraud. Credit unions and credit card companies need to detect fraud in order to find account information, products, or materials. Any industry can serve customers better if frauds are detected early before they become serious. Credit card companies and banks, for example, can identify fraudulent transactions or stolen cards with big data analytics before cardholders notice that it is amiss.
4. Increased productivity according to a survey by Syncsort.
59.9% claimed they used big data analytics tools such as Spark and Hadoop in order to improve productivity. The increase in productivity helped customers retain their business and improve sales. Data scientists and analysts can now efficiently analyze large amounts of data using modern big data tools, which allows them to quickly see more details.
It also improves their productivity. Big data analytics also helps data scientists, data analysts and other data professionals gain information that allows them to identify ways they can be more productive and efficient in the performance of their jobs and activities. All industries can benefit from big data analytics to increase their productivity and stand out.
5. As part of any company’s marketing strategy, improving customer relations is a key component.
Big data analytics gives businesses more data, allowing them to target marketing efforts and create highly customized offers for each client. Social media, email transactions and customer CRM systems are the main sources of big data. It exposes businesses to a vast amount of data about customers, their pain points, touchpoints and values. This allows them to better serve customers. Big data allows companies to understand their customers and offer personalized services and products. A personalized customer experience is a great way to improve customer satisfaction and build trust.
6. Achieving greater agility is another competitive advantage that big data offers.
Companies can become more innovative and flexible in the market by using big data analytics. Companies can gain valuable insights from huge customer data sets to help them be more competitive and better address their customers’ needs. Companies can also use huge data sets to enhance their communications and products and improve risk management. Big data can also help companies to improve their business strategies and tactics. This is a great way for them to align their efforts in support of frequent, faster industry changes.
There are some disadvantages.
AtScale survey shows that the greatest challenge facing this industry for three years has been the shortage of data scientists and big data specialists. Many IT professionals are not able to perform big data analysis because it is a skill that requires different skills. It can therefore be difficult to find data scientists with expertise in big data.
Data scientists and big data specialists are highly-paid careers within the field of data science. Hiring big data analysts is a costly task, particularly for startup companies. Companies may have to wait a while to find the right staff for their Big Data Analytics tasks.
Security threats
Companies often collect sensitive data for large-scale analytics. Security risks are possible due to inadequate maintenance. Your business could be the target of cyber-attacks if hackers have access to large data sets.
Data breaches are a major threat for many businesses today. Big data also poses a risk because important information could be leaked by competitors if you don’t take the necessary precautions.
Compliance
Big data can also be a problem because it requires compliance to all applicable laws. Big data that contains sensitive or private information should be stored, processed, managed, maintained, and complied with by the organization. Data governance, storage, and transmission will be more challenging as companies become more involved in the management of big data.
