Additionally, what is a relational database What are the advantages and disadvantages of relational database? This type of database is a very powerful database as it deals with the relations which makes the data manipulations easier other than any other database. It has the features of data entry, data deletion, and creating of new entry and records etc. the database provides the ease of accessing and maintaining data easily.
Consequently, what are the disadvantages of relational databases?
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.

Also highly trained staff is required to handle the database and it also needs continuous maintenance. All of these ends up making a database quite a costly venture.What are the disadvantages of database?
Disadvantages- Database systems are complex, difficult, and time-consuming to design.
- Substantial hardware and software start-up costs.
- Damage to database affects virtually all applications programs.
- Extensive conversion costs in moving form a file-based system to a database system.
What is the advantages of database?
Data consistency is ensured in a database because there is no data redundancy. All data appears consistently across the database and the data is same for all the users viewing the database. Moreover, any changes made to the database are immediately reflected to all the users and there is no data inconsistency.How do companies use relational database?
