  • Patent number: 11170002
    Abstract: Techniques are described herein for analyzing data streams in conjunction with relational database data in a DBMS. A database dictionary defines one or more columns for an external table and a data source for said external table that comprises an external message stream. Executing a query that targets the external table includes generating one or more rows from the external table, each row corresponding to a message in the external message stream that was retrieved from the external message stream after a message stream offset.

The preparation method of the process of the disclosure can realize high-efficiency and standardized industrial production. By injecting beef with the formulated gel emulsion, the fat content and high-quality protein content of the beef can be increased, thereby improving the sensory properties and flavor of the beef, and producing high-quality beef. The gel emulsion for preparing marbled beef of the disclosure is liquid and is low in viscosity when the temperature is higher than 40° C., and therefore the gel emulsion is convenient for injection into beef, and can be uniformly dispersed in beef to form a delicate marble pattern. When the temperature is lower than 20° C., the gel emulsion forms a solid in beef tissue.
