6 Advantages and Disadvantages of Relational Database | Limitations & Benefits of Relational Database

 

Relational databases: what are they?

Tables are a type of management system where data is stored in relational databases. For software engineers, it is the most popular method of storing complex data. The information can always be retrieved from the table once it has been saved there.


What are the examples for Relational database?

To establish relationships between these tables, primary keys and foreign keys are used. As a result, it greatly saves time.
Relational databases include, among others, Oracle, SQL Server, DB2, and Access.


Relational databases aren't perfect, even though they have several advantages over other kinds of databases. It has shortcomings, just like every other tool does. You can determine whether a relational database will be the best option for your project by weighing the benefits and drawbacks.

I'll be talking about the 6 Advantages and Disadvantages of Relational Database | Limitations & Benefits of Relational Database. You will learn about the pros and cons of relational database use from this essay.

Now let's get started, 

Advantages of Relational Database

1. Speed

Relational databases are easy to use and simple to understand, which contributes to their far quicker speed despite their poor performance. 

 

Furthermore, a relational database's numerous optimizations contribute to its increased speed. As a result, all programs utilized in relational databases will operate at the proper speed.


2. Security

A relational database has multiple tables, some of which might be designated as confidential. These tables are secured with a password and username, so only those with permission can access them. Only that particular table may be worked on by the users.


3. Simplicity

The relational database model is significantly more straightforward than other kinds of network models. It does not require complicated organization or query processing. 

 

Consequently, it doesn't need any intricate inquiries. A straightforward SQL query will suffice to handle the situation.


4. Accessibility

A relational database does not require a specific path to access the data, in contrast to other database types. It's even simple to edit data in the pertinent column. Therefore, whatever result is displayed is suitable for the user. 

5. Multi User Support

A relational database allows for simultaneous access by several users. Users may conveniently access the data, even after it has been updated. Therefore, it's possible that the crashes caused by multiple access will not occur. 

6. Accuracy

Primary keys and foreign keys are used by relational databases, as previously discussed, to establish relationships between the tables. As a result, every piece of recorded data is unique. 

 

This implies that there are no duplicates in the data. As a result, the accuracy of the data saved is ensured. 

Disadvantages of Relational Database

1. Cost

The foundational expenses associated with a relational database are high. A separate piece of software must be purchased in order to set up a relational database. 

 

Additionally, the system should be maintained by a qualified technician. These can all be expensive, particularly for small enterprises.


2. Performance

The amount of tables in a relational database always affects its performance. The response time to queries will increase with the number of tables. 

 

Furthermore, a larger amount of data causes the system to slow down and eventually makes information retrieval more difficult. As a result, relational databases are thought to operate more slowly.

 

3. Complexity

Relational databases don't have complicated structuring, although they can occasionally get complex as well. A relational database's complexity inevitably rises with the volume of data it contains. Since the data is ordered based on shared features, every single piece of data is complex. 

 
4. Physical Storage

Because relational databases have rows and columns, they also demand a massive amount of physical memory. Every action requires its own physical store. The targeted programs can only be made to have the maximum amount of physical memory through appropriate optimization.


5. Information Loss

Big businesses typically employ more database systems with more tables in them. Transferring this data from one system to another is possible. Data loss could occur from this.


6. Structure Limitations

There are restrictions on the fields that are available in relational databases. Fundamentally, limitations indicate that additional information cannot be accommodated. 

 

Even with further information, data loss can result. As a result, it is required to provide the precise data volume that will be provided to the field.
