Understanding Database Engines
Database engines play a crucial role in managing and storing data for organizations, and choosing the proper database engine is essential for efficient data storage and retrieval. There are primarily two types of databases: relational databases and NoSQL databases. Relational databases offer structured data storage suitable for web applications, ERP, CRM, and banking systems. In contrast, NoSQL databases provide flexibility and scalability for unstructured data, big data, and real-time analytics.
Ultimately, the right database management system for your organization depends on various factors such as data structure, scalability, performance, security, and what you will use your database for. Exploring different database management systems and evaluating their features and capabilities is essential to make an informed decision. For example, is Mysql suited for analytics?
A relational DB is a type wherein data is organized in tables, with each table related to the other and each row representing a record identified by its primary key. Relational databases, such as Oracle and MySQL, offer organized data storage and maintain ACID (Atomicity, Consistency, Isolation, Durability) properties, making them well-suited for web applications, ERP, CRM, and banking systems. Data arranged in a row-column order is most conducive to a relational database and are often called SQL databases. In contrast, key-value databases, a type of NoSQL database, are more suitable for simple data models and high-performance applications.
IBM Db2 is another example of a relational database that supports relational, object-relational, and object-oriented features for transactional data workloads. Its flexibility, efficiency, scalability, reliability, and security make it a popular choice among database administrators in database technology.
In contrast, NoSQL databases like MongoDB provide adaptability and scalability for unstructured data, making them ideal for handling data that doesn’t fit neatly into tables.
A NoSQL database, such as MongoDB, Redis, and Elasticsearch, is another type of database management system that offers flexibility and scalability and is suitable for managing unstructured data, big data, and real-time analytics. They differ from relational databases because they do not employ the tabular relation methodology of relational database models and are often called “document databases”. Rapid implementation for agile software development is another advantage of NoSQL databases.
There are three main types of NoSQL databases: document databases, key-value stores, and graph databases. Document databases, such as MongoDB, store data in formats like JSON, making them a popular choice for modern applications requiring flexibility and scalability. Key-value stores like Redis are suitable for simple data models and high-performance applications. At the same time, graph databases like Neo4j are perfect for handling large data volumes and complex relationships between entities.
NewSQL databases, such as Singlestore, combine the benefits of relational and NoSQL databases, offering scalability and ACID properties for modern applications. They are particularly beneficial for the finance and banking, e-commerce, and enterprise management sectors that require ACID properties in data transactions. Additionally, SQL databases, like columnar databases, can be a part of the NewSQL solutions, providing efficient data storage and retrieval.
By providing a balance of scalability and performance, this new database management system caters to the growing demands of contemporary applications that need both the structure of relational databases and the flexibility of a NoSQL database.
In memory databases
As the price of memory decreased and memory capacity increased, in-memory databases have become popular to power specific applications. Redis, Aerospike, Apache Ignite, Vitess, and many more are often used to cache and scale critical applications. Some of them are used as key-value databases, search engines, full-text search, etc… These database systems have very low latency, allowing fast access to data. Vertical and horizontal scaling can be easily accomplished by upgrading the server size (and its memory) or adding additional resources to the pool.
