## Abstract

Provided are a time series data management unit that manages time series data generated in a target system, and a context management unit that manages a context registered by a user in association with time series data managed by a time series data management unit. The context management unit executes a process of extracting time series data associated with a context set as a search target by the user out of the managed time series data.

## Claims

### Claim 1

A data management device comprising:
a time series data management unit that manages time series data generated in a target system; and
a context management unit that manages a context registered by a user in association with the time series data managed by the time series data management unit,
wherein the context management unit executes a process of extracting time series data associated with the context set as a search target by the user out of the managed time series data.

### Claim 2 (depends on 1)

The data management device according to claim 1, further comprising:
a user interface that receives an input of the user; and
a context storage table that stores the registered context,
wherein the context management unit causes the user interface to display a context registration screen configured to register the context on a terminal used by the user.

### Claim 3 (depends on 2)

The data management device according to claim 2, wherein
the context management unit causes the user interface to display a context assignment screen, configured to assign the context to the time series data corresponding to a condition designated by the user, on the terminal used by the user.

### Claim 4 (depends on 3)

The data management device according to claim 3, wherein
in a case where a type of the time series data and a target period are designated by the user on the context assignment screen through the user interface, the context management unit acquires the context stored in the context storage table, and displays the acquired context on the context assignment screen as a candidate for a context to be assigned to the time series data for which the type and the target period are designated in a user-selectable manner.

### Claim 5 (depends on 1)

The data management device according to claim 1, wherein
the time series data management unit acquires a conversion rule in which an association between the time series data generated in the target system and time series data used for search by the user is registered, and converts the time series data managed by the context management unit in accordance with the conversion rule, and
the context management unit executes a process of extracting time series data associated with the context set as a search target by the user out of the converted time series data.

### Claim 6 (depends on 5)

The data management device according to claim 5, further comprising:
a user interface that receives an input of the user; and
a conversion rule management table that stores and manages the conversion rule,
wherein the time series data management unit causes the user interface to display a conversion rule registration screen configured to register the conversion rule on a terminal used by the user.

### Claim 7 (depends on 6)

The data management device according to claim 6, wherein
at least one of a name conversion of the time series data managed by the context management unit, a unit conversion of the time series data, and an arithmetic expression using the time series data is defined as the conversion rule.

### Claim 8

A program for causing a computer, provided in a data management device that manages time series data generated in a target system, to execute:
managing a context registered by a user in association with the time series data;
receiving the context to be searched out of the time series data from the user; and
extracting time series data associated with the context set as a search target by the user.
