Why Developers Are Ditching SQL Pain Points with Open-Source SPL
- SQL is efficient for basic data operations but struggles with non-database data sources, while SPL processes file data directly.
- SPL simplifies complex tasks by avoiding the need to load data into a database environment.
- SPL's flexible design reduces the skill threshold for language usage and offers advantages over SQL for intricate computations.
- In SPL, coding complex logic resembles building blocks, allowing clear and concise code implementation.
- SQL, on the other hand, requires nested queries and window functions for complex tasks, making code challenging to write and understand.
- SPL provides robust debugging features, such as breakpoint setting and real-time result viewing, enhancing interactive analysis.
- In contrast, SQL lacks debugging functionalities, forcing users to troubleshoot by dissecting code layers and re-executing queries.
- SPL facilitates efficient and effortless handling of complex tasks, offering simplicity, procedural syntax, and interactive debugging.
- SQL, with nested CTEs and cumbersome conditions, produces convoluted code that compromises performance and readability.
- SPL's open-source nature and user-friendly features present a viable alternative to SQL for data analysis, addressing common pain points.

Multi Tenant Architecture in Software: What Is It and Its Databases Patterns
- Multi-tenant architecture is an approach where a single instance of an application serves multiple tenants.
- Each tenant in this architecture can be a company, a group, or an individual user, with isolated and customized data.
- Multi-tenant architecture differs from user accounts by offering isolated data and configurations for each tenant, allowing customization.
- Different database patterns can be used in multi-tenant applications, such as one database and one schema for all tenants, a database for each tenant, or one database with different schemas for each tenant.
