This page provides a guide to Establishing a Connection to Yahoo! JAPAN DATA SOLUTION in CData Cloud, as well as information on the available resources, and a reference to the available connection properties.

Connecting to Yahoo! JAPAN DATA SOLUTION

Establishing a Connection shows how to authenticate to Yahoo! JAPAN DATA SOLUTION and configure any necessary connection properties to create a database in CData Cloud

Accessing Data from CData Cloud Services

Accessing data from Yahoo! JAPAN DATA SOLUTION through the available standard services and CData Cloud administration is documented in further details in the CData Cloud Documentation.

Connect to Yahoo! JAPAN DATA SOLUTION by selecting the corresponding icon in the Database tab. Required properties are listed under Settings. The Advanced tab lists connection properties that are not typically required.

Connecting to Yahoo! JAPAN DATA SOLUTION

In order to authenticate, you must specify the following:

• AppID : The App ID is used for authentication. Send a request to the Yahoo! JAPAN DATA SOLUTION support team to obtain this.

Customizing the SSL Configuration

By default, the Cloud attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store.

To specify another certificate, see the SSLServerCert property for the available formats to do so.

Connecting Through a Firewall or Proxy

HTTP Proxies

To connect through the Windows system proxy, you do not need to set any additional connection properties. To connect to other proxies, set ProxyAutoDetect to false.

In addition, to authenticate to an HTTP proxy, set ProxyAuthScheme, ProxyUser, and ProxyPassword, in addition to ProxyServer and ProxyPort.

Other Proxies

Set the following properties:

• To use a proxy-based firewall, set FirewallType, FirewallServer, and FirewallPort.
• To tunnel the connection, set FirewallType to TUNNEL.
• To authenticate, specify FirewallUser and FirewallPassword.
• To authenticate to a SOCKS proxy, additionally set FirewallType to SOCKS5.

Overview

This section shows the available API objects and provides more information on executing SQL to Yahoo! JAPAN DATA SOLUTION APIs.

Key Features

• The Cloud models Yahoo! JAPAN DATA SOLUTION entities like documents, folders, and groups as relational views, allowing you to write SQL to query Yahoo! JAPAN DATA SOLUTION data.

Views

The Cloud enables access to read-only Views, such SearchTrends and SearchRankings.

Views are similar to tables in the way that data is represented; however, views are read-only.

Queries can be executed against a view as if it were a normal table.

CData Cloud - Yahoo! JAPAN DATA SOLUTION Views

Name	Description
SearchMapMetrics	SearchMapMetrics View gets information about area attributes such as prefecture-specific characteristics of the specified keyword.
SearchRanking	Gets the keyword information related to the specified keyword in the ranking format.
SearchTrend	Gets a list of keywords whose search trends are rising over a specified period of time.
SearchVolume	Gets the search volume for keywords for the specified time period.

SearchMapMetrics View gets information about area attributes such as prefecture-specific characteristics of the specified keyword.

Select

The Cloud will use the Yahoo! JAPAN DATA SOLUTION API to process WHERE clause conditions built with the following column and operator. The rest of the filter is executed client side within the Cloud.

This property indicates whether or not to include pseudo columns as columns to the table.

Data Type

string

Default Value

""

Remarks

This setting is particularly helpful in Entity Framework, which does not allow you to set a value for a pseudo column unless it is a table column. The value of this connection setting is of the format "Table1=Column1, Table1=Column2, Table2=Column3". You can use the "*" character to include all tables and all columns; for example, "*=*".

The value in seconds until the timeout error is thrown, canceling the operation.

Data Type

int

Default Value

60

Remarks

If Timeout = 0, operations do not time out. The operations run until they complete successfully or until they encounter an error condition.

If Timeout expires and the operation is not yet complete, the Cloud throws an exception.
