Graph analytics is the best method used to understand relationships. Using graph analytics for big data has become popular. However, before the availability of cloud computing, it was tough to determine how small or large a graph should be outside of the laboratory environment. But the innovation of cloud computing has paved the way for graph analytics. 

Graph analytics make use of algorithms to discover the relationships among entries in a graph database. This included relations among different people, or organizations, or transactions. For doing analytics on such graphs, data requires an alteration of present deep learning algorithms to take benefit of the graph structure instead of the flat geometry of relational tables. Just like text analysis, graphs can be converted into vectors and can be studied with linear techniques because both words in a text and nodes in a graph are determined by their context. 

Using graph analytics for big data allows for quicker decision-making that includes mechanized decisions. Graph analytics can determine and analyze all kinds of networks. For instance, identifying YouTube influencers and which vlog is going viral, etc. also, recommendation engines are a classic example of graph analytics. 

Graph analytics, which is an analytics alternative uses an abstraction called a graph model. The ease of this model is that it allows for fast absorption and connection between large volumes of data from many sources in a way that expertise limitations of the source. Graph analytics is a substitute to the old-style data warehouse model as an outline for absorbing both structured and unstructured data from different sources to allow analysts to review the data in an undirected manner.

Graphs help in spotting significant complex relationships between different components and lots of prevailing casualty trails in a huge data set. 

Old-style metadata and analytics were created to behave in a certain way in a given situation. But with changing situation we cannot expect the existing metadata to work in a similar way or cannot expect to get a successful outcome. 

In the COVID 19 pandemic, a special report is published regarding the use of graph analytics for big data in order to solve pandemic problems.
