List of the Top Relational Database in 2025 - Page 4

Introducing H2, a Java SQL database tailored for effective data management. In its embedded mode, applications can directly connect to the database within the same Java Virtual Machine (JVM) via JDBC, which is the fastest and most straightforward method of connection. Nevertheless, this configuration has a limitation: it restricts database access to a single virtual machine and class loader at any given time. Similar to other operation modes, it supports both persistent and in-memory databases, allowing for an unlimited number of simultaneous database accesses or open connections. Conversely, the mixed mode merges characteristics of both embedded and server modes, where the first application connecting to the database functions in embedded mode, while concurrently initiating a server for other applications in separate processes or virtual machines to access the same data at the same time. This combination facilitates local connections to benefit from the rapid speed associated with embedded mode, though remote connections might encounter minor latency. Ultimately, H2 stands out as a versatile and powerful solution capable of meeting diverse database requirements, making it an appealing choice for developers.

Apache Derby is a project under the Apache DB umbrella that functions as an open-source relational database, crafted entirely in Java and made available under the Apache License, Version 2.0. Its core engine, which includes an integrated JDBC driver, is remarkably lightweight at around 3.5 megabytes, emphasizing efficiency and ease of use. Derby features an embedded JDBC driver, enabling seamless integration into any Java-based application. Beyond its embedded functionality, it also supports a client/server setup via the Derby Network Client JDBC driver and Derby Network Server, thereby offering diverse options for database management. This versatility and lightweight nature make Derby an attractive option for developers in search of a flexible database solution that can easily adapt to various project needs. Furthermore, its open-source nature allows for community contributions and enhancements, further solidifying its position in the database management landscape.
