Although blockchain was originally designed to support cryptocurrency transactions, its use has greatly expanded. Due to its security mechanisms and immutability feature, blockchain is now also used for a variety of applications. Nevertheless, blockchain is facing several challenges. On the other hand, databases have been on the market for decades, offering a wide range of affordable solutions. In this paper, we explore the possibility of combining blockchain and database technologies, taking into account the specifics of their corresponding characteristics and issues. The case study was conducted by analyzing and classifying papers into three categories: blockchain as support for databases, databases as support for blockchain, and hybrid systems. Our research focuses on the improvement of technologies features and not on the performance improvement. Obtained results show the potential in developing combined solutions in all three categories taking into account the main advantages and disadvantages of both technologies.
