As a result, the same database can be viewed in many different ways. An important feature of relational systems is that a single database can be spread across several tables.

Is the RDBMS still dominant?

The RDBMS still remains the dominant platform for database applications by far, both in terms of mind and market share. Furthermore, the popularity of the RDBMS among software developers—generally a very good leading indicator of long-term technological market share—is dismal.

Why is RDBMS better than DBMS?

DBMS stores data as a file whereas in RDBMS, data is stored in the form of tables. DBMS has low software and hardware requirements whereas RDBMS has higher hardware and software requirements. In DBMS, data redundancy is common while in RDBMS, keys and indexes do not allow data redundancy.

What is RDBMS architecture?

Why is relational database most popular?

The reasons for the dominance of relational databases are: simplicity, robustness, flexibility, performance, scalability and compatibility in managing generic data.

What is the reason for the popularity of the relational model?

The simplicity of SQL – where even a novice can learn to perform basic queries in a short period of time – is a large part of the reason for the popularity of the relational model. The two tables below relate to each other through the product_code field.
