| content.faq | `[{"answer":"A database platform designed to self-manage through machine learning technology. Supports running on company-owned servers, cloud platforms, or both simultaneously, with built-in security and governance features. It is indexed under Relational Databases.","source":"https://www.ibm.com/products/db2","question":"What is IBM Db2?","confidence":0.6},{"answer":"IBM Db2 offers a free tier, so you can start without paying. Pricing changes often, so verify at source before relying on it.","source":"https://www.ibm.com/products/db2","question":"Is IBM Db2 free?","confidence":0.6},{"answer":"We have confirmed browser-based access to IBM Db2. That is the extent of what we could verify from public sources, so it may well offer desktop or mobile clients we have not indexed.","source":"https://www.ibm.com/products/db2","question":"What platforms does IBM Db2 support?","confidence":0.6},{"answer":"Yes. IBM Db2 can be deployed cloud / SaaS, hybrid and on-premise, so it does not have to run on the vendor's infrastructure.","source":"https://www.ibm.com/products/db2","question":"Can IBM Db2 be self-hosted?","confidence":0.6}]` | `[{"answer":"SQLite is a C-language library that provides a lightweight, self-contained SQL database engine with no external dependencies or separate server process. It is embedded directly into applications and is the most widely deployed database engine in the world, found in virtually all mobile phones and most computers.","source":"https://www.sqlite.org","question":"What is SQLite?","confidence":0.95},{"answer":"Yes. SQLite's source code is placed in the public domain by its authors and contributors. Anyone is free to copy, modify, use, compile, and distribute SQLite for any purpose—commercial or non-commercial—without requiring permission or payment.","source":"https://www.sqlite.org/copyright.html","question":"Is SQLite open source and free?","confidence":0.98},{"answer":"SQLite is designed as a replacement for file input/output operations like fopen() and fread(), not as a replacement for enterprise database servers like Oracle or PostgreSQL. It is optimized for storing structured data within applications with minimal overhead and configuration.","source":"https://www.sqlite.org/about.html","question":"What is SQLite designed to replace?","confidence":0.95},{"answer":"SQLite excels for embedded applications, mobile devices, local desktop applications, and low-to-medium traffic websites (under roughly 100,000 hits per day). Use a client-server database like PostgreSQL or MySQL if your application requires multiple concurrent writers, network database access, or extreme scalability.","source":"https://www.sqlite.org/whentouse.html","question":"When should I use SQLite versus a client-server database?","confidence":0.93},{"answer":"SQLite allows only one writer at a time, though multiple readers can work concurrently. Databases can theoretically reach 281 terabytes in size and support rows up to 1 gigabyte, though most deployments are considerably smaller and single-file-based.","source":"https://www.sqlite.org/about.html","question":"What are SQLite's concurrency and size limitations?","confidence":0.92},{"answer":"SQLite is highly reliable with ACID transaction support and aviation-grade testing including 100 percent branch coverage. It recovers cleanly from power failures and system crashes, making it suitable for critical embedded applications, though its single-writer model makes it unsuitable for high-concurrency server environments.","source":"https://www.sqlite.org/about.html","question":"How reliable is SQLite for production use?","confidence":0.94},{"answer":"SQLite provides a C API for direct integration and is widely supported by bindings in nearly every major programming language, including Python, JavaScript, Java, C#, Ruby, PHP, and others. Its public domain status allows libraries to be created for any language or platform.","source":"https://www.sqlite.org","question":"What programming languages can use SQLite?","confidence":0.9}]` |
