Advantages and Disadvantages of Relational Database – The Crazy Programmer

Relational databases are widely used databases by software developers and companies to store extensive data. These databases work as a collection of tables, and each table has relations with each others. Here raws are used in the table to show the relationship or real-world entity of the data.However, knowing only this much about the relational database is not sufficient. Hence, we have a fantastic post where you will learn about the relational database and some crucial advantages and disadvantages.What is Relational Database?The relational database refers to the collection of the relation between the values in the table. And it is the type of database that stores its data used in the form of a table where every row is used to contain data of every single user. The RDBMS is one of the widely used and accepted models that most developers prefer. Once the data is stored, it can be received whenever the developer needs to use the data.Examples of RDBMSIn RDBMS, the primary and foreign keys are used to build the relationship between the data set. That saves much time to monitor the stored data inefficiently. Some of the most famous examples of relational databases are SQL Server, Access, Oracle, and DB2.Advantages of Relational DatabaseThere are many advantages of relational databases, which make it the popular choice to store the data of the applications and platforms. Here are some significant advantages of relational databases or RDBMS.1. Secure OptionRDBMS uses tables with several rows, and these are highly secure options to store the data. These tables and data stay protected with the user names and their passwords. Hence only an authorized person can access those tables and data to work. The developer can give access to only those users who have the username and password, and they only get access to their allowed table.2. Simple to UseThere is not any process of query processing, and hence the relational databases are simple. And the user is not required to pass any complex query to access the data. However, if the user knows SQL query, this is more than sufficient. And they can successfully use the relational database without any problem.3. Fast PerformanceRelational databases are easy to use and also are simple by structure. Hence, it allows the user to get a fast experience. The user gets many optimization filters or options to increase the speed of the data accessing. So, the application works perfectly fine in the relational databases, and also the user gets a smooth experience.4. Present Data AccuratelyAnother advantage of using a relational database is that these databases are more likely to produce accurate and interrelated tables. As it uses the primary and foreign keys to make the relation between the raw. Thus, the users do not have any problem with the reputation of any past data they already have received. So, there are zero chances of duplication of the data in relational databases.5. Accessible AnytimeMany other types of databases require to have the specified path for getting access to the data. But here in the relational database, the user does not require any predefined path. Hence the accessibility in the RDBMS is easier compared to other databases. Moreover, users can also modify the data quickly, and hence it increases the chances of getting a more accurate result.6. It Can Have Multi-UserIt is one of the great benefits of relational databases as many users can access the database at one time. Even if the data is already updated, then also many users can visit without any issue. Thus, if the company uses relational databases, they can prevent the crash caused mainly by getting multi-user login in the database.Disadvantages of Relational DatabaseWe have discussed the advantages of relational databases, but there are some significant disadvantages of relational databases. And we also need to understand those to pick ideal RDBMS for use.1. Increase ExpenditureAs there are several attractive advantages of relational databases, hence these databases are pretty expensive to use. Also, the company or the user needs to purchase the software and tools to get the complete outcome of RDBMS. Hence, if the business has a low budget, it can feel hard to obtain such a database.2. Some Information Can Be LostThe RDBMS contains the limited space, and these storage devices can not store more data if there is no space. As there is no more storage, this data can be lost and create problems in the future. Thus, relational databases are limited and cause several issues if the company does not monitor them properly.3. Required to Use of Physical Storage DevicesIt also requires substantial storage devices, especially physical memory devices. Because it uses the raws and columns and every set of data uses separate rows for them. Thus, it becomes crucial to keep the physical devices that can help in proper optimization.4. Performance IssueThe performance level can be low in relational databases because it depends on rows and columns. Thus, if there are many raws and tables, the query will take more time to process the result. Also, if there is considerable data in the machine, it can slow down the working process. So, the performance issue is the disadvantage of a relational database that most users can face while using.5. It Can Be Complex to UnderstandWe have discussed that the relational database is easy to use, but this can also be challenging. When the amount of stored data increases, it becomes complicated to understand those data in simplified form. It happens because every data has kept using the particular feature that builds vast data sets to filter.ConclusionSo, relational databases are the databases that build the relation between data using primary key and foreign key in the table format that also has raw. In this article, we also learn about the advantages and disadvantages of relational databases. I hope now you have understood all this information and are willing to know more about similar topics.
