Crucial Inquiries to Make When Deciding on a Database for Your Project

Choosing a database among the vast number of options available can be a daunting task. It’s not a simple decision to make, but those who excel at it reap great rewards. While there is no precise formula to follow, there are several critical factors to consider. It’s important to abandon the notion that you can find the one ultimate database that surpasses all others. Instead, take a moment to ask yourself some crucial questions related to your project before delving into a particular database.

Let’s discuss the important questions to consider when choosing a database for your project.

How many users do you expect to handle simultaneously at peak load? This is important because different databases have different performance characteristics under load. If you expect to have a large number of concurrent users, you may need a database that can handle high levels of concurrency.

What availability, scalability, latency, throughput, and data consistency does your application need? This is important because different databases have different tradeoffs between these factors. You will need to decide which factors are most important for your application.

How often will your database schemas change? This is important because different databases have different mechanisms for schema changes. If you expect your schema to change frequently, you may need a database that can handle schema changes without downtime.

What is the geographic distribution of your user population? This is important because it can affect the latency and availability of your database. If your users are distributed around the world, you may need a database that can replicate data across multiple regions.

What is the natural “shape” of your data? This is important because different databases are optimized for different data structures. If your data has a natural graphlike structure, for example, you may want to consider a graph database.

Does your application need online transaction processing (OLTP), analytic queries (OLAP), or both? This is important because different databases are optimized for different types of queries. If you need to perform complex analytic queries, for example, you may want to consider a database optimized for OLAP.

What ratio of reads to writes do you expect in production? This is important because different databases have different performance characteristics for read-heavy and write-heavy workloads. If you expect a high ratio of reads to writes, for example, you may want to consider a database optimized for read-heavy workloads.

What are your preferred programming languages? This is important because different databases have different drivers and libraries for different programming languages. If you have a strong preference for a particular programming language, you may want to consider a database that has good support for that language.

Do you have a budget? If so, will it cover licenses and support contracts? This is important because some databases are open-source and free to use, while others require licenses and support contracts. You will need to consider the costs associated with each database option.

How strict are you with invalid data being sent to your database? This is important because it can affect the data quality and consistency of your database. It’s always recommended to have server-side data validation before persisting data to your database to ensure data integrity.
