The document discusses graph databases and their properties. Graph databases are structured to store graph-based data by using nodes and edges to represent entities and their relationships. They are well-suited for applications with complex relationships between entities that can be modeled as graphs, such as social networks. Key graph database technologies mentioned include Neo4j, OrientDB, and TinkerPop which provides graph traversal capabilities.

MongoDB is a document-oriented database that stores data in flexible, JSON-like documents. It supports features like replication, auto-sharding, and indexing. The document discusses using MongoDB with Ameba Pico's photo tagging service, including initial implementation with one shard, expanding to multiple shards as user numbers grow over time, and repairing and upgrading shards over time to support the increasing load.
The document discusses life hacks and web development. It mentions DevLOVE, Google, LifeHacks, matsukaz, TRICHORD, GAE/J, Slim3, JSONIC, iCal4j, and developing apps for iPhone, Android, Twitter, Google, and Facebook.
