An application coordinating system which is provided with an arithmetic unit, a storage device, and a display device, and which is for causing coordination between a coordination source application that manages a plurality of records and a coordination target application, the application coordinating system being characterized in that: the storage device has a coordination rule storage unit that stores a coordination rule including information pertaining to the coordination source application, a coordination item acquisition window which is a record display window of the coordination source application and which is such that an item value is acquired therefrom during coordination, a coordination acquisition item which is an item displayed within said coordination item acquisition window and which is such that an item value is acquired therefrom during coordination, a coordination target application, and a coordinated launch command format for causing the coordination target application to be launched in coordinated fashion with respect to the coordination source application; and provided therein are an item value acquirer that acquires the item value of the coordination acquisition item within the coordination item acquisition window displayed at the display device during coordination; and a coordinated launch command generator that generates a coordinated launch command which includes as launch parameter the item value acquired by the item value acquirer based on the coordinated launch command format during coordination, wherein a coordinated launch command is a command for causing coordinated launch of the coordination target application with specific conditions for items while causing item values acquired from the coordination source application to be passed to the coordination target application; execution of the coordinated launch command causes execution of coordinated launch such that the coordination target application is launched with the item value acquired by the item value acquirer serving as the launch parameter therefor during coordination. the storage device has a coordination rule storage unit that stores a coordination rule including information pertaining to the coordination source application, a coordination item acquisition window which is a record display window of the coordination source application and which is such that an item value is acquired therefrom during coordination, a coordination acquisition item which is an item displayed within said coordination item acquisition window and which is such that an item value is acquired therefrom during coordination, a coordination target application, and a coordinated launch command format for causing the coordination target application to be launched in coordinated fashion with respect to the coordination source application; and provided therein are an item value acquirer that acquires the item value of the coordination acquisition item within the coordination item acquisition window displayed at the display device during coordination; and a coordinated launch command generator that generates a coordinated launch command which includes as launch parameter the item value acquired by the item value acquirer based on the coordinated launch command format during coordination, wherein a coordinated launch command is a command for causing coordinated launch of the coordination target application with specific conditions for items while causing item values acquired from the coordination source application to be passed to the coordination target application; execution of the coordinated launch command causes execution of coordinated launch such that the coordination target application is launched with the item value acquired by the item value acquirer serving as the launch parameter therefor during coordination.
