10 Most Important Points To Keep In Mind While Creating A Database Design...
If you are a developer, then you might have faced a situation where you have to create a database design for your project. A database design is the most important part of a project because it holds a significant role in developing an application. So, we need to learn how to create a good database design and how to implement it in the project.
Before starting, it is important to know the purpose of creating a database. Why do you need to create a database? What are the benefits of having a database? If you have answered all of these questions, then you have understood the importance of database and the reason behind creating it.
Now, let’s move to the database design. A database design is the blueprint of your project. It includes the various tables, the fields, relationships, data types, etc. So, we need to understand what each and every point of a database design is and how it affects your project.
A database is a collection of data which is stored in the form of tables. A table is a data structure that consists of different columns and rows. A table contains different columns and rows. The row is the collection of data and the column is the type of data. So, the columns define the types of data while the rows contain the actual data.
Let’s discuss the various points of a database design.
1. Relational Database
As the name suggests, a relational database is a collection of data in which the information is stored in the form of tables and rows. Each and every row in the database is linked to the others.
It is easy to manipulate the data in a relational database because it allows you to store and retrieve the data in an organized manner. The relational database also has the ability to organize data into groups called relations.
2. Non-Relational Database
A non-relational database is a collection of data that is not related to one another. Unlike the relational database, non-relational databases don’t have any connections between the data.
The data in a non-relational database can be stored in the form of tables, but the tables are independent of each other. A non-relational database is suitable for storing large amounts of data.
3. NoSQL
NoSQL is a kind of non-relational database. It stores data in the form of objects. You can think of a noSQL database as the replacement of the relational database.
NoSQL databases are the most flexible and scalable solution for data storage. They are built to store and retrieve the data in an unstructured way.
4. Cloud-Based DB
Cloud-based DB is a combination of the database and the cloud. A cloud-based database is a collection of data that can be accessed from anywhere. The data stored in the cloud-based database can be retrieved, stored and deleted at any point of time.
5. Graphical Database
A graphical database is similar to the relational database, but it lacks the ability to store data in the form of tables. A graphical database can be considered as a hybrid of the relational and non-relational database.
6. Document Database
Document database is a collection of data that is stored in the form of documents. Documents are the basic unit of data in a document database.
7. Object Database
An object database is a collection of objects that are stored as records. An object is the basic unit of data in an object database.
8. Multidimensional Database
Multidimensional database is a collection of data that are stored in the form of cubes. Cubes are the basic unit of data in a multidimensional database.
9. Spatial Database
Spatial database is a collection of data that are stored in the form of shapes. Shape is the basic unit of data in a spatial database.
10. Hierarchical Database
A hierarchical database is a collection of data that is stored in the form of a tree. Tree is the basic unit of data in a hierarchical database.
Conclusion:
These are the most important points of a database design. I hope this post will help you to create an effective database design.
