SAFİR Big Data and Advanced Analytics Applications
What is Big Data,What are its Features?
In the event that classical methods, tools and infrastructures cannot be used to analyze, process and transfer data obtained from various sources, the concept of Big Data can be mentioned. In order for data to be big, it must have one or more components called 5V (Volume, Velocity, Variety, Value, Veracity).
Volume: Volume is directly related to the data size. By volume it is not just the size of the data in bytes. If the available data cannot be analyzed at the desired time, volume can be mentioned as a big data component.
Velocity: Social media, phone, sensors, etc. data can be produced very quickly by. When the data produced needs to be processed and analyzed in real time, speed emerges as a big data component.
Variety: In data analysis processes that require the use of many different types of data together, diversity is included as a big data component.
Veracity: The accuracy of the data is an important component that affects the analysis result. When analyzing data containing noise, it is necessary to make sure that the data is correct.
Value : Converting data into value is the main purpose of the analysis process. It is the most important feature that defines big data.
Types of Analytics in Data Science
Institutions that want to make decisions by using big amounts of data flow try to make sense by creating analytical solutions on this data. Analytical solutions that can be used can be evaluated under four different headings.
Descriptive Analytics: Descriptive analytics answers the question of “What happened?”. It gives an idea of the past using raw data but does not give information about the reasons. This type of analysis is performed with tools such as business intelligence applications and dashboards.
Diagnostic Analytics: Diagnostic Analytics answers the question of "Why did it happen?". It gives an idea of the root cause of the results using historical data.
Predictive Analytics: Predictive Analytics answers the question of "What will happen?" to predict the probability of a future outcome.
Prescriptive Analytics: Prescriptive Analytics answers the question of "How do I make it happen?". It gives information about how to achieve the desired result by predicting the effects before the actions are taken.
Big Data and Advanced Analytics Use Case Examples
360 ° Customer View: By using big data solutions, a 360-degree customer view can be obtained by combining data such as past online and offline interactions, social media data and purchasing history.
Providing a Personalized User Experience: Unlike the traditional e-commerce experience, it becomes possible to follow the products that customers are interested in and to offer personalized suggestions to the user including these products.
Suggestion Engines: Suggestion engines are algorithms implemented to provide appropriate offers for each customer. An example is presenting similar products that may be of interest to the customer while shopping on an e-commerce site.
Price Optimization: In business-to-consumer and business-to-business trade, the ability to control how competitors are pricing their products and determining the best pricing by looking at historical data becomes possible through big data analysis.
Predicting Trends: With the big data strategy, you can predict the trends in the market and the products that will sell next. Data from social media broadcasts and user internet browsing habits can be combined; With the sentiment analysis, it can be determined whether the comments about a product are positive or not.
Fraud Prevention: More sophisticated systems for fraud prevention can be developed with big data analytics and machine learning. With big data analytics, changing trends such as fraud aggregating in certain geographical regions (eg airports) can be quickly identified.
Reducing Data Warehouse Burden: Many businesses are changing or supplementing their data warehouses with open source big data solutions such as Hadoop. Hadoop-based solutions can provide faster performance while reducing license fees and other costs.
Log Data Analysis: The need for storing, processing and presenting log data in the most efficient and cost-effective way, which emerges from the exponential growth of commercial activities and transactions, is met with big data solutions.
Preventive Maintenance: Businesses in manufacturing, energy, construction, agriculture, transportation and similar sectors; it can take advantage of big data and industrial Internet of Things technologies to improve equipment maintenance. With big data solutions, it is possible to prevent possible accidents and costly line closures by analyzing data in real time and predicting when a problem will occur.
Internet of Things: Internet of Things and big data technologies can be used in all sectors to collect data and gain insights to take action. Monitoring product movements, weather conditions and security camera images are examples.
