The data source is a required part of the report object. Flexmonster supports data from OLAP data sources, SQL databases, CSV and JSON static files, and inline JSON data. Each data source requires specific properties to be set inside the dataSource section of the report object. Read more in the following sections:
OLAP data sources include Microsoft Analysis Services and Mondrian. There are two ways to connect to an OLAP cube using Flexmonster Pivot:
Here is a list of dataSource properties used to connect to Microsoft Analysis Services:
catalog – String. The data source catalog name.cube – String. The given catalog’s cube’s name.dataSourceInfo (optional) – String. The service info.dataSourceType – String. The type of data source. In this case it is "microsoft analysis services".proxyUrl – String. The path to the proxy URL. Both tabular and multidimensional model types are supported.binary (optional) – Boolean. A flag to use Flexmonster Accelerator instead of the XMLA protocol.effectiveUserName (optional) – String. Use when an end user identity must be impersonated on the server. Specify the account in a domain\user format.localeIdentifier (optional) – Number. The Microsoft locale ID value for your language.roles (optional) – String. A comma-delimited list of predefined roles to connect to a server or a database using the permissions defined by that role. If this property is omitted, all roles are used and the effective permissions are the combination of all roles. For example, to combine "admin" and "manager" roles, set the roles property like so: roles: "admin,manager".subquery (optional) – String. The parameter to set a server-side filter to decrease the size of the response from the OLAP cube. For example, to show reports for only one specific year, set the subquery like so: "subquery": "select {[Delivery Date].[Calendar].[Calendar Year].&[2008]} on columns from [Adventure Works]".Here is an example of how the connection to SSAS via XMLA is represented in dataSource:
{
dataSource: {
dataSourceType: "microsoft analysis services",
// URL to msmdpump.dll
proxyUrl: "http://olap.flexmonster.com/olap/msmdpump.dll",
catalog: "Adventure Works DW Standard Edition",
cube: "Adventure Works",
// Microsoft Locale ID Value for French
localeIdentifier: 1036,
// roles from SSAS
roles: "admin,manager",
subquery: "select
{[Delivery Date].[Calendar].[Calendar Year].&[2008]}
on columns from [Adventure Works]"
}
}
Check it out on JSFiddle.

Here is a list of dataSource properties used to connect to Elasticsearch:
dataSourceType – String. The type of data source. In this case it is "elasticsearch".subquery (optional) – Bool Query Object. The parameter to set a server-side filter to decrease the size of the response from the server.host (optional) – String|Object. The host for the connection (only for "elasticsearch" data source type). Can be set either as a URL string ("host": "https://olap.flexmonster.com:9200") or as a Host Object.index (optional) – String. The name of Elasticsearch index to connect (only for "elasticsearch" data source type).mapping (optional) – Object. An additional setting to configure index mapping (only for "elasticsearch" data source type). Use the name of the field as a key of the object with the following parameters:caption (optional) – String. Overrides the default name of the field.visible (optional) – Boolean. When set as false, hides the field from the Field List.interval (optional) – String. Used for date histogram. Check out supported time units.time_zone (optional) – String. Used for date histogram. You can specify timezones as either an ISO 8601 UTC offset (e.g. +01:00 or -08:00) or as a timezone ID as specified in the IANA timezone database, such as`America/Los_Angeles`. Check out the example.format (optional) – String. Used for date histogram. Check out date format/pattern.min_doc_count (optional) – Number. Used for date histogram. Can be used to show intervals with empty values (min_doc_count: 0). Default value: 1 (empty intervals are hidden).Here is an example of how the connection to Elasticsearch is represented in dataSource:
{
dataSource: {
dataSourceType: "elasticsearch",
host: "https://olap.flexmonster.com:9200",
index: "fm-product-sales"
}
}

Here is a list of dataSource properties used to connect to SQL databases using the Data Compressor:
dataSourceType – String. The type of data source. In this case it is "ocsv".filename – String. The URL to the server-side script which generates data.Flexmonster Data Compressor returns data in OCSV (Optimized CSV) format so you need to define dataSourceType explicitly:
{
dataSource: {
dataSourceType: "ocsv",
/* URL to the Data Compressor Node.js, .Net, Java, or PHP */
filename: "http://localhost:55772/api/flexmonster/get"
}
}
Read more about the Data Compressor here.
CSV data source can be:
Here is a list of dataSource properties used to connect to CSV data sources:
browseForFile – Boolean. Defines whether you want to load a file from the local file system (true) or not (false). Default value: false.dataSourceType – String. The type of data source. In this case it is "csv". You do not need to explicitly define this property when reading static CSV files with a “.csv” extension.fieldSeparator – String. Defines the specific fields separator to split each CSV row. There is no need to define it if the CSV fields are separated by , or ;. This property is required only if another character separates fields. For example if you use TSV, where a tab character is used to separate fields, then the fieldSeparator parameter should be set to "\t".thousandSeparator (optional) – String. Defines specific character used to separate groups of digits in numbers. For example, to import CSV data with commas used to separate groups of digits in numbers (e.g. 1,000 for one thousand), set thousandSeparator parameter as ",".filename – String. The URL to the file or to the server-side script which generates data.ignoreQuotedLineBreaks (from v2.1) – Boolean. Indicates whether line breaks in quotes should be ignored (true) or not (false). Default value: true – this makes CSV parsing faster. Set it to false only if your data source has important line breaks in quotes. Note that this might slow down CSV parsing a little bit.recordsetDelimiter – String. Defines which character is used in CSV to denote the end of a CSV row. Default value: "\n".
requestHeader (optional) – Object. This object allows you to add custom request headers. This object consists of "key": "value" pairs, where "key" is a header name and "value" is its value. Check out a live sample on JSFiddle. Important note: requestHeader is not saved when obtaining the report via save() and getReport() API calls.In the following example data is taken from a CSV file where the colon character (:) is used to separate fields within the row. Line breaks in quotes are not ignored:
{
dataSource: {
/* URL or local path to a CSV file */
filename: 'colon-data.csv',
fieldSeparator: ':',
ignoreQuotedLineBreaks: false
}
}
If the data is generated by a server-side script, dataSourceType must be defined explicitly:
{
dataSource: {
dataSourceType: "csv",
filename: "script_which_returns_csv_data"
}
}
JSON data source can be:
Here is a list of dataSource properties used to connect to JSON data sources:
browseForFile – Boolean. Defines whether you want to load the file from the local file system (true) or not (false). Default value: false.
data (from v2.2) – JSON. The inline JSON data.dataSourceType – String. The type of data source. In this case it is "json". You do not need to explicitly define this property when reading static JSON files with a “.json” extension.filename – String. The URL to the file or to the server-side script which generates data.requestHeader (optional) – Object. This object allows you to add custom request headers. The object consists of "key": "value" pairs, where "key" is a header name and "value" is its value. Check out a live sample on JSFiddle. Important note: requestHeader is not saved when obtaining the report via save() and getReport() API calls.Here is an example of JSON data set using a file from the local file system:
{
dataSource: {
/* Path to the local JSON file */
filename: "data.json"
}
}
If the data is generated by a server-side script, dataSourceType must be defined explicitly:
{
dataSource: {
dataSourceType: "json",
filename: "script_which_returns_json_data"
}
}
Inline JSON:
{
dataSource: {
/* jsonData variable contains JSON data */
data: jsonData
}
}
Use the Connect option to choose another data source or Open to load another report at runtime. Use Save to save the report with the current data source.
Data in the pivot table will be updated and saved within the report.
The API calls connectTo(), load(), and open() are used to change the data source at runtime. The API call save() is used to save the report.
