[0023] The download control unit 17 controls the download of the data body from the data body storage unit 14 to the terminal device 2 .

[0024] FIG. 5 shows a configuration of the terminal device 2 according to the first embodiment.

[0025] The terminal device 2 includes a communication unit 21, a display unit 22, an application storage unit 23, an application information storage unit 24, a data storage unit 25, an application execution unit 26, an application attribute list identification unit 27, a data name selection unit 28, and a download control unit 29.

[0026] The communication unit 21 communicates with the data lake 1.

[0027] The display unit 22 displays the screen of the application.

[0028] The application storage unit 23 stores applications (software) of the department that uses the terminal device 2.

[0029] The application execution unit 26 executes an application for the department that uses the terminal device 2, which is stored in the application storage unit 23, in accordance with a user's instruction.

[0030] The application information storage unit 24 stores application information. Figures 6(a), (b), and (c) are diagrams showing examples of application information. The application information includes the application's function, the department using the application, and a list of application attributes. The application's function corresponds to data analysis, etc. The application's department corresponds to "Tokyo Branch, Elevator Department, Design Section," etc. The application's attribute list includes business, function, and region.

[0033] The download control unit 29 controls the download of the data body in the data lake 1 to the terminal device 2 .

[0034] The data storage unit 25 stores the data body downloaded from the data lake 1.

[0035] FIG. 7 is a flowchart showing the processing procedure of the data management method according to the data management system of the first embodiment.

[0036] In step S101, the application execution unit 26 of the terminal device 2 starts an application of the department that uses the terminal device 2, which is stored in the application storage unit 23, in accordance with an instruction from the user.

[0037] In step S102, the application attribute list specifying unit 27 of the terminal device 2 specifies the attribute list of the application being executed by reading the application information from the application information storage unit 24. The communication unit 21 transmits the application attribute list to the data lake 1.

[0038] In step S103, the communication unit 11 of the data lake 1 receives the application attribute list.

[0039] In step S104, the data name identification unit 15 of the data lake 1 refers to the data catalog stored in the data catalog storage unit 12 and identifies the data names of one or more pieces of data having an attribute list that matches the attribute list of the received application. For example, the data name identification unit 15 may identify the data names of one or more pieces of data having an attribute list that matches all of the business, function, and region in the attribute list of the application. However, if there is an item in the business, function, or region in the attribute list of the data in the data catalog that is not defined, the data name identification unit 15 may unconditionally determine that the item matches. For example, if the application's attribute list lists the business as "elevator," the function as "design," and the region as "Tokyo," and the data's attribute list lists the business as "elevator," the function as "none," and the region as "none," it is determined that the application's attribute list and the data's attribute list match.

[0040] In step S105, the communication unit 11 of the data lake 1 transmits one or more data names to the terminal device 2.

[0041] In step S106, the communication unit 21 of the terminal device 2 receives one or more data names.

[0042] In step S107, the data name selection unit 28 of the terminal device 2 selects one or more desired data names from the received one or more data names in accordance with an instruction from the user of the terminal device 2.

[0043] In step S108, the communication unit 21 of the terminal device 2 transmits one or more desired data names to the data lake 1.

[0044] In step S109, the communication unit 11 of the data lake 1 receives one or more data names.

[0045] In step S110, the access key identification unit 16 identifies one or more access keys for accessing data with one or more data names, and reads out one or more access keys stored in the access key storage unit 13. The communication unit 11 of the data lake 1 transmits the one or more access keys to the terminal device 2.

[0046] In step S111, the communication unit 21 of the terminal device 2 receives one or more access keys.

[0047] In step S112, the download control unit 29 of the terminal device 2 and the download control unit 17 of the data lake 1 use one or more access keys to control the download of the data body stored in the data body storage unit 14 of the data lake 1 to the terminal device 2. The download control unit 29 of the terminal device 2 stores the received data body in the data storage unit 25.

[0048] According to this embodiment, when a person in charge uses a data lake, the person in charge can save time and effort in selecting the necessary data from the data catalog.

[0049] Embodiment 2 Even in large companies, work is not completely divided organizationally, and some work is still tied to individuals. One reason for this is that when employees are transferred to a new department or restructured, they continue to carry out work from their previous department. Therefore, even if applications are introduced for each department or division, they do not support work tied to individuals who have been transferred.

[0050] In this embodiment, a system is provided that allows employees (called special users) who have been transferred from other departments and have personal tasks to view data from their previous department via applications used by their current department. This allows the special users to utilize data necessary for work in their previous department by using applications from their current department.
