Tabular model put SSAS in front seat of Data modeling, Data mining and BI World. With graph databases you can even add more relationships and still maintain performance. It limits redundancy and replication of the data. An overview of the advantages and disadvantages of graph databases: Answer (1 of 4): I believe that the pros are over the cons. Where core data objects or data model stay consistent and data structure is fixed and tabular. Finally, we discussed the advantages and disadvantages of each data structure in terms of space and time complexity, and when to use each data . A consequence of this is that query latency in a graph database is proportional to how much of the graph you choose to explore in a query, and is not proportional to the amount of data stored, thus defusing the join bomb . Attempting to correct this can make charts overly complex, which can make their value in aiding a presentation less useful. On the other hand, multi-model databases store, query, and index data from different models. The data in such databases are stored in the form of edge, nodes and properties. The previous answers have already done a good job of summarising the advantages and disadvantages of graph databases. Generally, data than can be modeled on a graph database can also be modeled on a relational database.
