| content.faq | `[{"answer":"A tool for managing database schemas declaratively as code, supporting schema migrations, security policies, data lineage, and multiple database backends. Includes both open-source and cloud-hosted versions with audit capabilities. It is indexed under ORM & Database Tools.","source":"https://atlasgo.io/blog/2024/03/03/pricing-change","question":"What is Atlas?","confidence":0.6},{"answer":"Atlas is open source, so it can be self-hosted and used at no licence cost. It is released under the Apache-2.0 licence. Paid editions are also offered: Atlas Pro and Atlas Cloud, priced on request. Pricing changes often, so verify at source before relying on it.","source":"https://atlasgo.io/blog/2024/03/03/pricing-change","question":"Is Atlas free to use?","confidence":0.6},{"answer":"Atlas supports the web and a command-line interface. Platforms we have not confirmed are simply not listed here rather than ruled out.","source":"https://atlasgo.io/blog/2024/03/03/pricing-change","question":"What platforms does Atlas support?","confidence":0.6},{"answer":"Yes. Atlas can be deployed cloud / SaaS, on-premise and self-hosted, so it does not have to run on the vendor's infrastructure.","source":"https://atlasgo.io/blog/2024/03/03/pricing-change","question":"Can Atlas be self-hosted?","confidence":0.6},{"answer":"We have confirmed 3 integrations for Atlas, including GitHub, AWS Marketplace and Slack. This is what we could verify from public sources, so the vendor may support others we have not indexed.","source":"https://atlasgo.io/blog/2024/03/03/pricing-change","question":"What does Atlas integrate with?","confidence":0.6},{"answer":"We have independently confirmed SOC 2 and GDPR for Atlas. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Atlas not holding them. Always confirm compliance directly before you rely on it.","source":"https://atlasgo.io/guides/clickhouse/security-declarative","question":"What security certifications does Atlas have?","confidence":0.7},{"answer":"Yes. Atlas is published under the Apache-2.0 licence, a permissive licence that generally allows commercial use and modification. Licence terms can change between releases, so verify against the repository for the version you intend to use.","source":"https://github.com/ariga/atlas","question":"Is Atlas open source?","confidence":0.95},{"answer":"Atlas is available worldwide. The vendor is headquartered in the United States.","source":"https://atlasgo.io/blog/2024/03/03/pricing-change","question":"Where is Atlas available?","confidence":0.75}]` | `[{"answer":"SQLAlchemy is a Python library that provides both an Object-Relational Mapping (ORM) layer and a SQL expression toolkit for interacting with relational databases. It abstracts away low-level SQL details, allowing developers to work with database objects as Python classes and manage database queries programmatically rather than writing raw SQL strings. This approach reduces code repetition, improves maintainability, and makes database interactions more Pythonic.","source":"https://www.sqlalchemy.org","question":"What is SQLAlchemy and what problem does it solve?","confidence":0.95},{"answer":"Yes, SQLAlchemy is completely free and open-source, distributed under the MIT license. There are no licensing fees, commercial tiers, or restricted versions - the software is available for both personal and commercial use at no cost. The project accepts voluntary donations and sponsorships to support ongoing development.","source":"https://www.sqlalchemy.org","question":"Is SQLAlchemy free and open-source?","confidence":0.98},{"answer":"SQLAlchemy supports all major relational databases through a dialect system, including PostgreSQL, MySQL, MariaDB, SQLite, Oracle Database, Microsoft SQL Server, and others. Each database is accessed through a specific dialect implementation that handles database-specific features and SQL syntax variations. This modular approach allows developers to write largely database-agnostic code while still accessing database-specific capabilities when needed.","source":"https://docs.sqlalchemy.org/20/","question":"What databases does SQLAlchemy support?","confidence":0.94},{"answer":"SQLAlchemy Core is the lower-level SQL toolkit that handles direct SQL expression construction, engine configuration, connection pooling, and schema definition without requiring object mapping. The ORM layer builds on top of Core and allows mapping Python classes to database tables, enabling object-oriented patterns for CRUD operations and relationship management. Developers can use either layer independently depending on their needs - Core for complex queries, Core for building query builders, and ORM for domain-driven database interactions.","source":"https://docs.sqlalchemy.org/20/","question":"What's the difference between SQLAlchemy's ORM and Core layers?","confidence":0.93},{"answer":"Yes, SQLAlchemy provides built-in support for asyncio-based applications, allowing non-blocking database operations in async frameworks like FastAPI and Starlette. Async support requires compatible database drivers (such as asyncpg for PostgreSQL) and is available in both the ORM and Core layers. This enables developers to write concurrent, high-performance applications without blocking the event loop.","source":"https://docs.sqlalchemy.org/20/","question":"Does SQLAlchemy support asynchronous database operations?","confidence":0.91},{"answer":"Yes, SQLAlchemy is widely deployed in production environments at organizations ranging from startups to enterprises. It provides enterprise-level features including connection pooling, query optimization capabilities, relationship eager-loading strategies, and support for complex schema patterns. However, developers must understand performance implications and implement proper indexing and query optimization for high-traffic or data-heavy applications.","source":"https://docs.sqlalchemy.org/20/","question":"Is SQLAlchemy suitable for large-scale and production applications?","confidence":0.92},{"answer":"Common Python ORMs and database tools include Django ORM (tightly integrated with Django), Peewee (lightweight ORM), Tortoise ORM (async-first ORM), and SQLModel (combines SQLAlchemy with Pydantic for validation). Django ORM is best suited for Django projects, while SQLAlchemy is framework-agnostic and works equally well with Flask, FastAPI, or standalone applications. Each tool has different philosophies regarding API design, performance characteristics, and feature sets.","source":"https://www.sqlalchemy.org","question":"What are common alternatives to SQLAlchemy for Python developers?","confidence":0.86},{"answer":"SQLAlchemy was created by Michael Bayer and continues to be actively maintained as an open-source project with contributions from a community of developers. The project follows semantic versioning and regular release cycles with both major versions (like version 2.0) that introduce breaking changes and minor/patch releases for new features and bug fixes. The development is transparent, with public code repositories and community involvement in decision-making.","source":"https://www.sqlalchemy.org","question":"Who maintains SQLAlchemy and how is it developed?","confidence":0.88}]` |
