BSON is a computer data interchange format used mainly as a data storage and network transfer format in the MongoDB database. It is a binary form for representing simple data structures and associative arrays (called objects or documents in MongoDB). The name "BSON" is based on the term JSON and stands for "Binary JSON".〔(BSON Specification )〕 ==Data types and syntax== BSON documents (objects) consist of an ordered list of ''elements''. Each element consists of a field name, a type, and a value. Field names are strings. Types include: * string * integer (32- or 64-bit) * double (64-bit IEEE 754 floating point number) * date (integer number of milliseconds since the Unix epoch) * byte array (binary data) * boolean ( true and false)* null * BSON object * BSON array BSON types are nominally a superset of JSON types (JSON does not have a date or a byte array type, for example〔(JSON Specification )〕), with one exception of not having a universal "number" type as JSON does. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「BSON」の詳細全文を読む スポンサード リンク
