Types of Databases: 2 Ways to Create an Online Database Easily in 2023
In today’s digital age, databases play a pivotal role in our daily lives. From social media platforms to e-commerce websites, databases are the backbone of countless applications and systems.
That is why understanding the importance of databases is crucial for anyone involved in technology, business, or decision-making roles. This article will provide a comprehensive overview of database design and its significance for your business. But, let’s start with the basics.
What is a Database?
A database is an organized collection of data structured in a way that allows efficient storage, retrieval, and manipulation of information. With adequate database design, businesses can:
- Streamline operations
- Enhance the decision-making processes
- Ensure the accuracy and accessibility of the data
- Improve data quality
- Reduce redundancy
- and provide a solid foundation for data-driven applications.
So, it really is a tool that you can implement into your business that could drive your growth. But to better understand what a database is, and essentially how to design it, you will also need to understand the basic concepts that come with designing a killer database. So let’s get into further detail.
The 4 Basic Concepts of Database Design
There are multiple elements that come with database design. However there are three key elements that you must get familiarized with. Here is a breakdown of those four elements and what purpose they have in database design.
|Table||Tables are the foundation of the database that consist of rows and columns like this one.||In a customer database, a table might have columns for the customer’s information, and each row would represent a unique customer.|
|Field or Record||Fields, or records, store individual pieces of data within a table and hold the values for each attribute.||In the customer table, the field for customer name might contain values like “John Smith”.|
|Relationships||Relationships between tables establish connections and dependencies enabling data querying capabilities.||In a relational database, a relationship might exist between a customer table and an order table which ensures that each order is associated with the correct customer.|
|Data Integrity||Data integrity ensures that the data is accurate and consistent.||Database constraints can be used to enforce rules such as unique values or referential integrity between related tables, like user authentication and access control.|
Now that you understand what a database is and the basic concepts, you can determine if a database would be an asset to organizing your data. And when it comes down to creating it, there are two approaches you could take. So let’s get into them so you can decide which best fits your needs.
Relational Database Vs. Non-Relational Database: Which Approach is Better?
When it comes to database design, two primary approaches dominate the industry: relational databases and non-relational databases. Let’s break down what each of the approaches are about and some of their pros and cons.
|Type of Database||Relational Database||Non-Relational Database|
|What it is||Relational databases follow a structured format where data is organized into tables with predefined relationships.||Non-relational databases are schema-less and store data in a variety of formats.|
|Used for||Scenarios that require complex data relationships and transactions.||Scenarios where data access patterns are unpredictable or require high-speed data retrieval.|
|Pros||Easily manipulate data Use of constraints which ensures that data meets certain criteriaCompliant with the ACID (Atomicity, Consistency, Isolation, and durability) properties||You can scale horizontally allowing for distributed data storage.Handle high traffic loadsAccommodate growing data volumes without sacrificing performance. Allows for efficient querying and retrieval of data.|
|Cons||Not as flexibleNot as scalable||They may sacrifice consistency in favor of performance.|
Though, neither of these design principles may be necessary given that we are in the 21st century and no-code online database builders are extremely common. If you aren’t interested in designing from scratch, then let’s take a look at what no-code can do for your business.

Conceptual Design: The 4 Steps to Planning Your Database
Before diving into database design, proper planning is crucial to ensuring a solid foundation as this phase lays the groundwork for the logical and physical design stages. Here is a quick rundown of what goes down during the stage of conceptual design.
Step 1 | Gather the Data
Stakeholders, including end-users, managers, IT professionals, and database designers must first gather the requirements for the database including entities, attributes, and relationships. This information serves as a blueprint for the subsequent stages of the database design process.
Step 2 | Identify Key Entities
Identifying key entities is a critical step in the conceptual design process. Entities can be:
- Tangible objects, such as customers or products
- or intangible concepts, such as orders or invoices.
By identifying these entities, the database designer can determine the necessary attributes to include in the database schema.
Step 3 | Define Relationships between Entities
Defining relationships between entities is another crucial aspect of conceptual design. Relationships can be one-to-one, one-to-many, or many-to-many, depending on the nature of the entities involved. These relationships help establish the structure and integrity of the database.
Step 4 | Create an Entity Relationship Diagram (ERD)
The last step is to create an entity-relationship diagram which provides a visual representation of the database’s structure, making it easier to understand and communicate. It showcases the entities as rectangles, attributes as ovals, and relationships as lines connecting the entities.
During the collaboration between stakeholders and database designers, the ERD may undergo several iterations to refine and finalize the design. Feedback and input from all parties involved are crucial to ensuring that the database meets the requirements and expectations of the end-users.
By investing time and effort into the conceptual design stage, you can lay a solid foundation for the subsequent stages of database design. As the next step, the logical design, will heavily depend on the end result of the conceptual design.
Logical Design: The 5 Steps to Creating Your Database
The logical design phase is where the conceptual model transforms into a fully defined structure. It involves translating the ERD into a formal representation of tables, fields, keys, and relationships. Here is how to go about your logical design:
Step 1 | Data Normalization
Data normalization is a vital aspect of database design that eliminates redundancy and minimizes data anomalies.The data normalization process involves organizing data into multiple tables, each serving a specific purpose. By reducing redundancy and ensuring that each table stores only relevant data, normalization helps to prevent data inconsistencies and anomalies.
Step 2 | Analyze Entities and Attributes
During the logical design phase, designers meticulously analyze the entities and attributes identified in the conceptual model and determine which entities will become tables and which attributes will become fields within those tables, as well as establishing the relationships between them.
Step 3 | Consider the Constraints
The next step is a careful consideration of the cardinality and participation constraints identified in the conceptual model. By accurately representing these constraints, designers ensure that the database can effectively store and retrieve data in a meaningful way.
Step 4 | Identify Primary and Foreign Keys
Another important aspect of logical design is the identification and definition of primary and foreign keys. Primary keys uniquely identify each record in a table, while foreign keys establish relationships between tables.
Step 5 | Consider Performance Optimization
During the logical design phase, designers also consider performance optimization. They analyze the expected volume of data, the types of queries that will be executed, and the relationships between tables to design an efficient database structure.
The logical design phase is a crucial step in the database design process. By carefully crafting a logical design, database designers lay the foundation for a robust and efficient database system. They will then be ready to move onto the implementation.
Physical Design: The 5 Steps to Database Reality
Once the logical design is complete, the focus shifts to the physical design of the database. The physical design involves determining how the data will be stored, indexed, and accessed. These are the steps of the physical design phase:
- Select the appropriate storage media
- Define data types and sizes
- Create indexes and partitions for improved query performance.
- Optimize the database schema
- And ensure data security
But now that you know the exact steps to take in order to design a killer database, the question arises: what do you use to design and implement a stellar database? There are really two routes you can take; the quick and dirty one, or the quick and smart one.
