- Lack of scalability: Relational databases can struggle with scalability as the data grows in size and complexity.
- Performance issues: Join operations and complex queries can lead to slower performance in relational databases.
- Data redundancy: Normalization in relational databases can result in storing data in multiple tables, leading to redundancy and inefficiency.

Advantages and disadvantages of relational data model?
Advantages of relational data model include data integrity through normalization, flexibility to query data using SQL, and ease of understanding relationships between entities. Disadvantages can include performance issues with complex queries, potential for data duplication across tables, and difficulty in scaling for very large datasets.
What is the advantage of relational database model?
The advantages are as follows: The relational database model is by far the most widely used. It is easier to control, more flexible, and more intuitive than other approaches because it organizes data in tables. The relational model can also be used with personal computers and mainframe systems. It allows tables to be linked. This linkage is especially useful when information is needed from multiple tables.
Which type of database model connects data in different files through the use of a key field?
The relational database model connects data through the use of a key field, which is called a primary key in one table and a foreign key in another table. This key field establishes a relationship between different tables by uniquely identifying records.
Which term does a user of a relational database use to refer to a file?
A user of a relational database typically refers to a file as a "table." Tables in a relational database store data in rows and columns, following a structured format to allow for efficient data storage and retrieval.
What is a database that stores data in tables that consist of rows and columns?
A relational database.
What is the most popular database model?

Limitations and benefits of rational database model?
One of the advantages of a relational database model is that the broken keys and records and the data complexity are usually simplified. The disadvantage of the relational database model is that it requires sophisticated processing power which is very costly.
What are the Advantages and disadvantages of relational data base model?
Some of the advantages of relational databases include the ability to link information about a particular person who is in several databases together by simple links. One disadvantage is that once the database is created it is not changed easily so any database forming as part of a relational database must be very carefully planed before anything else can be done
Is MySQL DBMS or RDBMS?
AnswerMySQL, like most modern Database Management Systems is based on the relational model. So it is a RDBMS (Relational Database Management System).
What is a good way to represent a database?
Relational model of database is a good way to represent the database. Also network data model and hierarchical model can be used depending on the requirements.
What model was the Relational Database Management System based on?
The Relational Database Management System was based on a good model. It is based on first-order predicate logic which was discovered in 1969 by a man named Codd.

Compare between network hierarchal and relational model?
1. Relational Model : Newer database model; Network Model - Older database model 2. The network model structures data as a tree of records with each record can have multiple parent and child records, forming a lattice structure. The basic data structure of the relational model is the table, where information about a particular entity (say, an employee) is represented in columns and rows 3.The relational model has strong mathematical foundation with set theory and predicate logic. Network Model has no strong mathematical background. 4. Relational model is the most flexible of the database models. Network model is not very flexible. 5. Relational model has widespead use. Network model has limited use.
