![]() Performance is another critical factor when choosing a database management system. However, it lacks some features like right and full outer join and complete ALTER TABLE support. SQLite supports most of the SQL92 standard, including transactions, subqueries, and triggers. It provides enough functionality for a wide range of applications, especially those that require an embedded database. ![]() SQLite, being a lightweight and serverless DBMS, supports a subset of SQL. Both SQLite and PostgreSQL support a wide range of SQL commands and features, but there are significant differences in their levels of SQL compliance. In the world of database management systems, SQL compliance is a crucial factor to consider. In the next sections, we will delve deeper into the SQL compliance and performance of SQLite and PostgreSQL, further illuminating the Postgres vs SQLite debate. PostgreSQL: Object-relational DBMS, designed for handling a wide range of workloads, supports complex data structures and a rich set of operators.SQLite: Embedded DBMS, serverless, zero-configuration, ideal for small-scale applications or as an embedded database within software applications.It’s designed to handle a range of workloads, from single-machine applications to web services with many concurrent users. This model extends the relational model by allowing complex data structures, user-defined types, and a rich set of operators. On the other hand, PostgreSQL uses an object-relational model. This means it’s serverless and requires zero-configuration, making it an excellent choice for applications that need an embedded database, such as mobile apps or small web applications. SQLite is an embedded database management system. When comparing SQLite and PostgreSQL, one of the most significant differences lies in their database models. Supports a variety of procedural languages Here is a table summarizing PostgreSQL’s key features: FeatureĪllows for custom functions, operators, and data typesĪllows for high concurrency and performance Procedural Languages: Postgres supports a variety of procedural languages, such as PL/pgSQL, PL/Python, PL/Perl, and others.Multi-Version Concurrency Control (MVCC): This feature allows for high concurrency and performance by creating a “snapshot” of data that allows each transaction to work with a consistent view of the data.Extensibility: Postgres allows for custom functions, operators, and data types.ACID Compliance: Postgres supports Atomicity, Consistency, Isolation, and Durability (ACID), ensuring data integrity.It supports both SQL (relational) and JSON (non-relational) querying, making it a versatile choice for a variety of projects. Postgres offers a wide range of features that ensure data integrity and consistency while providing developers with a robust set of tools to build complex applications. It was initially developed at the University of California, Berkeley in the 1980s and has since become one of the most advanced and feature-rich database systems available. PostgreSQL, often referred to as Postgres, is an open-source object-relational database management system (ORDBMS). In the next sections, we will explore PostgreSQL and compare it with SQLite to help you understand their differences and similarities. Works on a multitude of systems, from high-end servers to low-power embedded devices Small binary size, making it lightweight and efficient ![]() No separate server process or setup scripts neededįully ACID-compliant, allowing safe access from multiple processes or threads Here is a table summarizing SQLite’s key features: Feature
