MySQL Data Access Components vs. PostgreSQL Data Access Components vs. SQLGate vs. Sequelize Comparison Chart

Enjoy the highest performance and unlimited possibilities when working with PostgreSQL. PostgreSQL Data Access Components (PgDAC) is a library of components that provides native connectivity to PostgreSQL from Delphi and C++Builder including Community Edition, as well as Lazarus (and Free Pascal) on Windows, Linux, macOS, iOS, and Android for both 32-bit and 64-bit platforms. PgDAC is designed to help programmers develop really lightweight, faster, and cleaner PostgreSQL database applications without deploying any additional libraries. PgDAC is a complete replacement for standard PostgreSQL connectivity solutions and presents an efficient alternative to the Borland Database Engine (BDE) and standard dbExpress driver for access to PostgreSQL. It provides direct access to PostgreSQL without PostgreSQL Client. PgDAC allows developers to optimize their database applications and harness the full capabilities of PostgreSQL.

Sequelize is a modern TypeScript and Node.js ORM for Oracle, Postgres, MySQL, MariaDB, SQLite SQL Server, and more. Features solid transaction support, relations, eager and lazy loading, read replication, and more. Define your models with ease and make optional use of automatic database synchronization. Define associations between models and let Sequelize handle the heavy lifting. Mark data as deleted instead of removing it once and for all from the database. Transactions, migrations, strong typing, JSON querying, lifecycle events (hooks), and more. Sequelize is a promise-based Node.js ORM tool for Postgres, MySQL, MariaDB, SQLite, Microsoft SQL Server, Oracle Database, Amazon Redshift, and Snowflake’s Data Cloud. It features solid transaction support, relations, eager and lazy loading, read replication, and more. To connect to the database, you must create a Sequelize instance.
