What are the limitations of relational model?
Weaknesses of Relational Databases
- Impedance mismatch between the object-oriented and the relational world.
- The relational data model doesn’t fit in with every domain.
- Difficult schema evolution due to an inflexible data model.
- Weak distributed availability due to poor horizontal scalability.
What are the differences of relational and non relational databases and when would you use each one?
To summarize the difference between the relational and non-relational databases: relational databases store data in rows and columns like a spreadsheet while non-relational databases store data don’t, using a storage model (one of four) that is best suited for the type of data it’s storing.
What are some of the strengths and weaknesses of non relational databases?
Performance is lower than non-relational databases Performance is high. Data processing is slower than non relational databases Data processing is faster than relational databases. Complexity and cost of sharding is higher . Complexity and cost of sharding is lower than relational databases.
What are the advantages of a relational database compared to a non relational?
When compared to relational databases, NoSQL databases are often more scalable and provide superior performance. In addition, the flexibility and ease of use of their data models can speed development in comparison to the relational model, especially in the cloud computing environment.
What are the disadvantage of relational database?
Disadvantages of Relational Database
- Cost. The underlaying cost involved in a relational database is quite expensive.
- Performance. Always the performance of the relational database depends on the number of tables.
- Physical Storage.
- Complexity.
- Information Loss.
- Structure Limitations.
What are the disadvantages of using relational database?
Disadvantages of using Relational Model Relational databases can sometimes become complex as the amount of data grows, and the relations between pieces of data become more complicated. Complex relational database systems may lead to isolated databases where the information cannot be shared from one system to another.
What are the differences between relational and non relational databases?
So, what’s the difference? A relational database is structured, meaning the data is organized in tables. Many times, the data within these tables have relationships with one another, or dependencies. A non relational database is document-oriented, meaning, all information gets stored in more of a laundry list order.

What advantage do non-relational database?
The obvious advantage of a non-relational database is the ability to store and process large amounts of unstructured data. As a result, it can process ANY type of data without needing to modify the architecture. So, creating and maintaining a NoSQL database is faster and cheaper.
