Memgraph is a robust graph database that stores data as graph objects consisting of nodes and relationships, each capable of holding various properties with different data types. Nodes can have multiple labels for flexible data categorization, while relationships require a single, unchangeable type. Both nodes and relationships store properties akin to key-value pairs, with property values supported in numerous types such as strings, integers, floats, lists, maps, and several temporal and enumeration types. Memgraph's Cypher Query Language allows for the creation and manipulation of data using literal maps, map projections, and temporal types, offering a rich set of tools for building efficient graph-based applications. Understanding these data types enables developers to effectively manage and query data, accommodating both simple and complex data structures.
