Choosing the Right Database Could Make or Break Your Business — Here’s What You Need to Know
1. SQL Databases
Relational databases are the most commonly used type of database. They are based on a table structure, where data is organized into rows and columns. Relational databases are best suited for storing structured data that is consistent and predictable. They are commonly used in applications such as inventory management, customer relationship management, and financial systems.
Relevant Use Cases:
- Online Transaction Processing (OLTP) Systems
- Enterprise Resource Planning (ERP) Systems
- Customer Relationship Management (CRM) Systems
2. NoSQL Databases
NoSQL databases are a type of database that does not use a table structure. Instead, they use a document, graph, or key-value structure. NoSQL databases are best suited for storing unstructured or semi-structured data, such as social media posts or sensor data. They are commonly used in applications such as content management, Internet of Things (IoT) systems, and real-time analytics.
Relevant Use Cases:
- Big Data Applications
- Real-time Analytics
- Content Management Systems (CMS)
3. Graph Databases
Graph databases are a type of database that use a graph structure to represent and store data. They are best suited for storing data that has complex relationships, such as social networks or recommendation systems. Graph databases are commonly used in applications such as social media, e-commerce, and knowledge management.
Relevant Use Cases:
- Social Networks
- Recommendation Systems
- Knowledge Management Systems
4. Time-Series Databases
Time-series databases are a type of database that are designed to handle large amounts of time-stamped data. They are best suited for storing data that changes over time, such as sensor data or financial market data. Time-series databases are commonly used in applications such as IoT systems, financial systems, and operational analytics.
Relevant Use Cases:
- Internet of Things (IoT) Systems
- Financial Systems
- Operational Analytics
