| content.faq | `[{"answer":"A multimodel database that unifies fragmented enterprise data into a graph-native foundation, serving as a context layer for AI agents, applications, and analytics workloads without requiring multiple specialized databases. It is indexed under NoSQL Databases.","source":"https://www.arangodb.com","question":"What is ArangoDB?","confidence":0.6},{"answer":"ArangoDB does not publish its prices. Pricing is quoted on request, across 2 plans (Community Edition and Enterprise Edition), so the figure depends on your seat count and requirements. We record this as a pricing-transparency signal rather than guessing a number. Pricing changes often, so verify at source before relying on it.","source":"https://www.arangodb.com","question":"How much does ArangoDB cost?","confidence":0.6},{"answer":"Yes. ArangoDB can be deployed cloud / SaaS and self-hosted, so it does not have to run on the vendor's infrastructure.","source":"https://www.arangodb.com","question":"Can ArangoDB be self-hosted?","confidence":0.6}]` | `[{"answer":"MongoDB is a document database that stores data in flexible, JSON-like formats rather than rigid relational tables. It is designed for modern application development and supports various workload types including operational transactions, real-time search, vector search for AI applications, and streaming data processing. The flexible schema allows applications to evolve without downtime or schema migrations.","source":"https://www.mongodb.com/docs/manual/introduction/","question":"What is MongoDB and what type of database is it?","confidence":0.95},{"answer":"MongoDB is open source under the Server Side Public License (SSPL) v1.0, which requires that enhancements to MongoDB be shared with the community. Drivers are licensed under Apache License 2.0. MongoDB also offers a commercial license for organizations whose legal requirements are incompatible with SSPL, and a separately available MongoDB Enterprise Advanced edition.","source":"https://www.mongodb.com/community/licensing","question":"Is MongoDB open source and what license does it use?","confidence":0.95},{"answer":"MongoDB provides official client libraries for almost all modern programming languages and is compatible with popular application frameworks. Common stacks include MERN (MongoDB, Express, React, Node.js) and MEAN (MongoDB, Express, Angular, Node.js). Developers can access language-specific API documentation and driver references for their chosen technology stack.","source":"https://www.mongodb.com/docs/","question":"What programming languages and frameworks does MongoDB support?","confidence":0.92},{"answer":"MongoDB offers three deployment models: MongoDB Atlas, a fully managed cloud service available on AWS, Azure, and Google Cloud; MongoDB Enterprise Advanced for self-managed on-premises or private cloud deployments; and MongoDB Community Edition for open-source local development. Each option provides different levels of automation, support, and operational responsibility.","source":"https://www.mongodb.com","question":"What deployment options are available for MongoDB?","confidence":0.93},{"answer":"MongoDB Atlas operates on a pay-as-you-go model with a free-forever M0 tier (512 MB storage) for learning and exploration, flexible hourly clusters for development, and dedicated clusters starting around $57 per month for production workloads. Enterprise Advanced pricing is custom and available through direct sales. Costs vary based on cluster size, storage, data transfer, and optional add-on services like vector search and stream processing.","source":"https://www.mongodb.com/pricing","question":"What is MongoDB's pricing model?","confidence":0.9},{"answer":"MongoDB includes encryption at rest and in transit via TLS/SSL, multiple authentication methods (SCRAM, X.509, Kerberos, LDAP, OIDC), role-based access control, queryable encryption, client-side field-level encryption, IP access lists, and audit logging. MongoDB Atlas comes preconfigured with secure default settings and supports network peering and private endpoints across major cloud providers.","source":"https://www.mongodb.com/docs/manual/security/","question":"What enterprise security features does MongoDB provide?","confidence":0.92},{"answer":"MongoDB uses flexible JSON-like documents instead of rigid table schemas, allowing data models to change without downtime. Embedded documents and arrays reduce the need for joins, which can improve query performance for certain workloads. The lack of enforced schemas supports polymorphic data structures where different documents in the same collection can have different fields, though this flexibility requires different application design patterns than relational databases.","source":"https://www.mongodb.com/docs/manual/introduction/","question":"What are the main differences between MongoDB and traditional relational databases?","confidence":0.93},{"answer":"Yes, MongoDB is a unified platform that combines operational data, vectors, and streaming in a single system. It includes vector search for semantic queries and AI-powered applications, stream processing via Apache Kafka integration using familiar MongoDB syntax, and real-time analytics with aggregation pipelines. This consolidation of multiple workload types can be more efficient than managing separate specialized databases.","source":"https://www.mongodb.com","question":"Can MongoDB handle real-time analytics, vector search, and streaming data?","confidence":0.91}]` |
