The database industry is shifting its focus towards graph databases, which are increasingly being used by companies like Twitter and Facebook to store relationships and activity between users. Graph databases are based on the mathematics of graph theory and store data in terms of nodes, properties, and edges. These databases are finding applications in social media platforms, online dating sites, and even analytics engines that pull data from various sources. The use of graph databases is becoming more widespread as companies look to leverage their power for relationship-based analysis and recommendation systems.
