The storage of big data is the main issue for industries which is the major concern of this Tesco big data case study and also for facilities as they are revolutionizing the manner they store and analyze intelligence. The highly connected digital economy with the help of the IoT is changing the financial system of data as a commodity. Although big data analytics and storage bring many advantages to the company, it often needs industries to cross associational boundaries. Compared with traditional methods, data identification through analysis is a very complicated process [1]. Those who perform data analysis should be proficient in the areas and technologies utilized for analytics and data solutions. Still, this is a growing field, and the isolation between analysts and the preparation of data and decision-makers is disappearing. The Business Analytics and Big Data division is expected to develop by 29% over the next five years. The mixture of simple access to quality tools and data for analysis will help to attain a good quality of life and higher operational competence. It will help to establish evidence-based standards for policy development. Small public sector entities now apply big data analytics to multinational companies such as Tesco in developed markets. However, due to the lack of data, big data analysis is not general in emerging countries. It is stated in the Tesco big data case study that in the absence of data, big data analysis methods cannot be applied. Big data and Tesco can be synonymous with their size because big data has the same probability as Tesco, and Tesco can be as large as big data [2]. Nowadays retail stores not only accumulate customer information to share product discounts and offers but however they also know, interpret and integrate consumer data to make the best use of that data to drive sales and revenue. The starting point is usually a business challenge, product or idea. It can be optimizing pricing, making predictions before technical problems occur, personalizing customer communication for products, maintaining business security, managing risk, reducing fuel costs or almost anything else. Within an hour, cross-functional teams in any business can often solve hundreds of problems that can be solved with data. The next step mentioned in this Tesco big data case study is to prioritize several issues that can achieve a clear return on investment in the short to medium term with relatively limited effort. Addressing several different types of problems first ensures that the solution is flexible and extensible and supports more than a single-use case.

The forecasting technology they use has begun to pull in huge amounts of data from a variety of different sources. It helped Tesco improve customer service through personalized services. Prediction technology combines machine learning techniques to automatically improve the accuracy of algorithms and integrate them with various internal and external data sources.

Big data analysis can only be executed using large amounts of data, so it cannot be applied in numerous developing finances where the essential data cannot be obtained. Such as, in developing countries like southern Sudan, it's not probable to perform data analysis to predict vaccine immunization requirements because of insufficient information. In Ukraine, information restrictions sometimes lead to stock-out. Both private and public sector entities must make an evidence-based decision. However, in this Tesco big data case study, it is ordinary to use inadequate data for uncertain analysis [7].

Big data is very large, complex and huge data sets so that current and contemporary or traditional data processing applications will become insufficient. Big data can more effectively address the modern challenges of the traditional data processing applications, such as data search, management, sharing, visualization, updating, transmitting, querying, analyzing, information privacy, and capturing. It refers to utilize predictive analytics to remove some value from the raw data that will serve as a reference and basis for surer decision-making.
