Challenges and Benefits of Deploying Big Data Storage Solution

Since data is at the heart of information systems, new technologies and approaches dealing with storing, processing and analyzing data have proliferated. Data Warehouses are among the most known approaches that tackle data storing and processing. However, they reached their limits in dealing with large quantities of data as those of Big Data. Consequently, a new concept which is an evolution of Data Warehouse known as "Data Lake" is emerging. This paper presents a detailed analysis that compares Data Lake and Data Warehouse key concepts. It sheds lights on the aspects and characteristics for the sake of revealing similarities and differences. It also emphasizes the complementary of the two technologies by showing the most appropriate use case of each of them.
