SQLAlchemy offers tools for database schema generation, querying, and object-relational mapping. Key features include: A comprehensive embedded domain-specific language for SQL in Python called "SQLAlchemy Core" that provides means to construct and execute SQL queries. A powerful ORM that allows the mapping of Python classes to database tables.
One of the arguments against using an OODBMS is that it may not be able to execute ad-hoc, application-independent queries. [ citation needed ] For this reason, many programmers find themselves more at home with an object-SQL mapping system, even though most object-oriented databases are able to process SQL queries to a limited extent.
A plugin system [8] CherryPy plugins hook into events within the server process — into server startup, server shutdown, server exiting, etc. — to run code that needs to be run when the server starts up or shuts down. Built-in tools for caching, encoding, sessions, authorization, static content, and others.
In software engineering, the data mapper pattern is an architectural pattern.It was named by Martin Fowler in his 2003 book Patterns of Enterprise Application Architecture. [1]

The Web Server Gateway Interface (WSGI, pronounced whiskey [1] [2] or WIZ-ghee [3]) is a simple calling convention for web servers to forward requests to web applications or frameworks written in the Python programming language.
Trino is an open-source distributed SQL query engine designed to query large data sets distributed over one or more heterogeneous data sources. [1] Trino can query data lakes that contain a variety of file formats such as simple row-oriented CSV and JSON data files to more performant open column-oriented data file formats like ORC or Parquet [2] [3] residing on different storage systems like ...
Domain-specific languages which are embedded into user applications (e.g., macro languages within spreadsheets) and which are (1) used to execute code that is written by users of the application, (2) dynamically generated by the application, or (3) both. Many domain-specific languages can be used in more than one way.
