I usually use SQLite for development/ unit testing, and use PostgreSQL in production. To give you a bit of background: I've done a lot of work with Python/SqlAlchemy lately (coming from a C++/C# background), and have become a huge fan. Make sure you really need C++ here, compared to Python you will need a lot more time to get things running. Venturing out into database territory is a lot harder with C++. Look closely at the SQL queries it generates (set echo to True in the engine connection), and learn. Start with SqlAlchemy and play around with the ORM (Object Relational Mapper). So by all means, start with SQLite, learn a lot, and try other databases later (I would recommend PostgreSQL).Ībout Python/C++: if you start, Python is a lot easier to work with than C++. When using good libraries (such as SqlAlchemy) the cost of migration can even be (close to) zero. Migration is generally easy when you stick to standard SQL queries and data types. SQL, modelling, JOIN queries, transactions etc. Apart from that, relational databases are very much alike. The big difference with MySQL is that MySQL is a database server, like almost every other database. It is a full-blown relational database, just an embedded one. Just jump in!ĭon't be fooled by SQLite, it's present everywhere: in your browser, in your phone, in applications. Need a quick edit on the go? Download TablePlus for iOS.Either is a great place to start. Not on Mac? Download TablePlus for Windows. Need a good GUI Client to work with PostgreSQL or SQLite? TablePlus is a modern, native GUI that allows you to simultaneously manage multiple databases such as MySQL, PostgreSQL, SQLite, Microsoft SQL Server… faster and easier. PostgreSQL gives you the functionality to maintain such a complex database smoothly without limitations. Custom Procedures which is extensible to run the complex task.Data integrity and reliability is highly concerned.Apps need to read or write files to disk directly.Small apps that don’t require expansion.SQLite is somewhat limited to basic operations while the strength of an advanced RDMS like PostgreSQL is its extendibility with stored procedures. ACID stands for Atomicity, Consistency, Isolation, and Durability, and these are important for reliable transactions. Due to its advanced features, installation and configuration of PostgreSQL are much more complex.Installing and running an SQLite DB is pretty easy even for the most novice users.A lot of security features, as well as complicated configurations, are built-in PostgreSQL to protect the database.The database file itself can be updated/read by anyone. SQLite does not provide an authentication system.When it comes to complex operations, PostgreSQL is a beast. If all you require is fast read operations, PostgreSQL can be an over-kill and might appear less performant. SQLite is very fast, thanks to its minimal design and simple operations.SQLite: Basic feature set suited for most common uses.PostgreSQL handles multiple users and with clear levels of permission very well.SQLite does not have user management as well as handle multiple simultaneous access.PostgreSQL is only portable after you export it to a file and upload to another server.The file format used is also cross-platform, so can easily be copied and moved. SQLite stores the database in a single ordinary disk file that can be located anywhere in the directory.The SQLite library is less than 500kb while PostgreSQL is much larger in size. PostgreSQL supports almost everything that you can think of.SQLite supports only five types: BLOB, NULL, INTEGER, TEXT, REAL.PostgreSQL on the other hand works based on a client-server model which requires a DB server to set up and run over the network.SQLite is an “embedded” database which means it’s server-less and can run within your app.PostgreSQL: The world’s most advanced open source database.SQLite: Ultra-lightweight in setup, administration, and required resource.They are both open-source and free, but they have some major differences that should be considered when choosing a database to use for your business. SQLite and PostgreSQL are among the most widely used relational database management systems (RDMS).
