Limitations of Relational Database Systems


  1. Relational databases are based on relational algebra, which requires data to be stored must be modeled as relational only. This also means that, data read from RDBMS modeled back in its original model (say tree, graph, key value, or any other). This requires significant stress on computing resources.
  2. Columns of tables can only store similar data.
  3. Document storage (images, multimedia, business documents, XML, etc) is big sore point for RDBMS
  4. RDBMS is not real time system. It is poll based.
