The present invention discloses a database system. The database system comprises a database server, a network server, and a client. The database server uses a memory database and is configured to store data. The network server is deployed with multiple network services for the client to invoke, wherein the multiple network services are separately used for operating the memory database, acquiring result data returned by the memory database, and feeding back the acquired result data to the client. The client comprises a searching module, wherein the searching module is configured to acquire a query condition and operate the memory database according to the query condition and by invoking a network service. According to the database system provided by the present invention, a memory database is used, and a network service is appropriately equipped, so that data analysis efficiency is greatly improved, an architecture is clear, deployment is convenient, and custom-built development can be performed according to requirements of a client. Therefore, it is convenient for the client to perform detailed control on a data analysis result at any time, and the result can be presented more intuitively.
