Data Source

Static Source

Create

The code to create a StaticSource is given below:

StaticSource source = new StaticSource(dataTable);

In the above code:

  • dataTable is the DataTable.
  • Create an instance/object of StaticSource(source) with the DataTable dataTable.

Dispose

The code to dispose the StaticSource object is given below:

source.Dispose()

In the above code, source is the object of StaticSource class.

MSSQL Source

Apart from Static Source, you can also use data from MSSQL server.

Configure data source

To fetch the data from MSSQL, connect the DataEngine to the server. DataEngine can be connected to the server in the following ways:

SQL Authentication

If the MSSQL server has SQL authentication, refer to the command given below:

/* create object */
/* SQL Authentication */

MsSqlClass msSql = new MsSqlClass("username", "password", "servername", "databasename", sourcetype, "sourcename")

In the above command:

  • username is the username for the MSSQL server.
  • password is the password for the MSSQL server.
  • servername is the name of the MSSQL server.
  • databasename is the name of the database you want DataEngine to connect to.
  • sourcetype is the type of data source you want DataEngine to fetch the data from. It is an enum of type DataBaseClass.SourceType. It can take the values of TABLE, VIEW, or QUERY.
  • sourcename is the name of the data source. If you want DataEngine to use a table or a view as the source, provide the name of the respective table/view. If you want to use the result of a query as the source, provide the query string.

Windows Authentication

If the MSSQL server has Windows authentication, refer to the command given below:

/* create object */
/* Windows Authentication */
MsSqlClass msSql = new MsSqlClass("servername","databasename", sourcetype, "sourcename")|

In the above command:

  • servername is the name of the MSSQL server.
  • databasename is the name of the database you want DataEngine to connect to.
  • sourcetype is the type of data source you want DataEngine to fetch the data from. It is an enum of type DataBaseClass.SourceType. It can take the values of TABLE, VIEW, or QUERY.
  • sourcename is the name of the data source. If you want the DataEngine to use a table or a view as the source, provide the name of the respective table/view. If you want the DataEngine to use the result of a query as the source, provide the query string.

Connection String

To use a different type of authentication, provide a connection string to the DataEngine. Refer to the command given below:

/* create object */
/* provide connection string from user end */
MsSqlClass msSql = new MsSqlClass("connectionstring", sourcetype, "sourcename")

In the above command:

  • connectionstring is a string that specifies information about a data source and the means of connecting to it. The connection string may include attributes such as the name of the driver, server, database and security information such as username and password.
  • sourcetype is the type of data source you want DataEngine to fetch the data from. It is an enum of type DataBaseClass.SourceType. It can take the values of TABLE, VIEW, or QUERY.
  • sourcename is the name of the data source. If you want the DataEngine to use a table or a view as the source, provide the name of the respective table/view. If you want to use the result of a query as the source, provide the query string.

CSV File

Local File

The code to fetch data from a CSV file stored in the local computer is given below:

CsvFileSource csvFileSource = new CsvFileSource("filePath");

In the above code filepath is the complete path to the CSV file in the local computer. It is used to create an instance/object of CsvFileSource (csvFileSource).

File from another network

The code to fetch data from a CSV file stored in another network is given below:

CsvFileSource csvFileSource = new CsvFileSource("filePath", "userName", "password");

In the above code:

  • filepath is the complete path to the CSV file in the local computer. It is used to create an instance/object of CsvFileSource (csvFileSource).
  • userName and password are the credentials needed to log in to the target network. They are also used to create an instance/object of CsvFileSource (csvFileSource).

Dispose the object

The code to dispose the csvFileSource object is given below:

csvFileSource.Dispose();

In the above code, csvFileSource is the object that holds the file configuration.

JSON File

Local File

The code to fetch data from a JSON file stored in the local computer is given below:

JsonFileSource jsonFileSource = new JsonFileSource("filePath");

In the above code filepath is the complete path to the JSON file in the local computer. It is used to create an instance/object of JsonFileSource(jsonFileSource).

File from another network

The code to fetch data from a JSON file stored in another network is given below:

JsonFileSource jsonFileSource = new JsonFileSource("filePath", "userName", "password");

In the above code:

  • filepath is the complete path to the CSV file in the local computer. It is used to create an instance/object of CsvFileSource (csvFileSource).
  • userName and password are the credentials needed to log in to the target network. They are also used to create an instance/object of CsvFileSource (csvFileSource).

The code to dispose the JsonFileSource object is given below:

jsonFileSource.Dispose();

In the above code, jsonFileSource is the object that holds the file configuration.
