Ranked in these QuestionsQuestion Ranking
Pro Great language support
An SQLite database is a single ordinary disk file that can be located anywhere in the directory hierarchy. It works by sending requests to a single file where all the data is kept instead of communicating with a hosted database which gives access to an interface by making use of sockets and ports. The file format used is also cross-platform, so can easily be migrated to various machines.
This makes SQLite extremely portable throughout different applications, all that's needed to transfer the whole database is to make a copy of the file.
SQLite is largely self-contained. It requires very minimal support from external libraries or from the operating system.
SQLite is also only 350KiB in size.
Pro Not unnecessarily fiddly
Pro Great for testing and first stages of development
Because of it's ability to scale and with the portability that a single-file database gives you without losing much of the power and features that SQL gives developers, it's a great choice for testing applications and for the early stages of development when the workload and the data that needs to be stored is not that large.
Pro Zero configuration
There is literally no configuration required to get SQL lite up and running. This is mainly due to SQLite being serverless, there is no separate server process to install, setup, configure, initialize, manage, and troubleshoot.
With less complication, there is less to go wrong.
Pro Ability to run ad-hoc SQL like queries on realtime big data
Couchbase N1QL allows native SQL processing over JSON data with high performance indexing for low latency queries at scale.
Pro Open source
Couchbase and Couchbase Mobile are open source and released under the Apache License.
Pro Ability to make predefined fast queries
With Couchbase you can make "Views" of data, which are practically predefined queries which are fetched with an O(1) algorithm.
Con Some SQL features are missing
SQLite is made to be extremely lightweight and portable, but it still uses SQL. However, some SQL features such as
RIGHT OUTER JOIN and
FOR EACH STATEMENT are missing.
Con No model mapper for Android
Couchbase does not have a model mapper for Android built-in and out of the box, instead you will have to write your own from scratch.
