As companies grow in size and further digitize their various processes, the demand for database developers to categorize and classify data has skyrocketed. Several companies have turned, or are planning to shift to NoSQL technologies for this. It is advisable to get a general grasp on the various technologies in this field instead of focusing exclusively on one. Hadoop, Cassandra, and Couchbase are some notable players. Salaries in this area are also quite generous, with developers making INR 4,15,000 per annum on average. However, depending on location, company, and experience, salaries may reach as high as INR 7,80,000 per annum.
