摘要： Methods and systems for searching multiple databases are presented. Search connectors are defined between a first and second database, including a search connector having a shared field of the first and second database. Edge connections are generated between the first and second database using the search connector. Each of the edge connections include one or more instances of the shared field in the first and second database. A search query is received from a user interface. The search query is mapped to one of the plurality of search connectors having a specific shared field. A specific instance of the specific shared field is returned, and may be one of the edge connections between the first and second database. In another example, a natural language search query is received, and is translated using the defined search connectors. In a further example, data corresponding to the view name is imported.

摘要： According to one aspect of the present disclosure, a turbomachine (100) is provided. The turbomachine includes: a rotor extending in an axial direction and comprising a driven side configured to be connected to a driving unit and a second side opposite the driven side; a housing extending around at least a portion of the rotor, wherein a main flow path for a process fluid extends between the rotor and the housing; a sealing arrangement, particularly a dry gas seal, configured for sealing a gap between the rotor and the housing at the driven side of the rotor; and a first magnetic bearing supporting the second side of the rotor. A fluid passage for a portion of the process fluid extends from the main flow path through a bearing gap of the first magnetic bearing. According to a further aspect, a method of operating a turbomachine is described.
