View source for Transfer Data to the Synthesis Data Warehouse (SDW)

{{Template:API}}{{Template:BacktoPrevPage}}

The Synthesis Data Warehouse (SDW) — formerly called "Reliability Data Warehouse" — is a temporary data storage location in a Synthesis repository. With the Synthesis API, you can transfer data from external sources into the SDW of a repository for use in Weibull++, ALTA or RGA standard folios. 

In this tutorial, you'll create a simple solution for copying data from a Microsoft Excel&#174; file over to the SDW. Note that the tutorial only demonstrates one particular approach for extracting data from Excel. It's for demonstration purposes only; it doesn't take efficiency into account and doesn't include any exception handling. 

==Prerequisites==
Before you begin:

*Reference the Microsoft Excel Object Library in your code. (In Visual Studio, choose '''Project > Add Reference''', and in the COM tab, select the latest version of the Microsoft Excel Object Library. Click '''OK'''.)

*Create a Synthesis repository for testing purposes.

*You'll also need to create a sample Excel file to complete the tutorial successfully. Copy and paste the following data to an Excel file. Be sure to select cell A1 in Sheet1 of the workbook when pasting the data. Name the Excel file, "SampleData."

==Tutorial: Transfer Data from an Excel File to the SDW==
The following example demonstrates how to transfer data from an Excel file to the Synthesis Data Warehouse (SDW). A discussion of the example follows.

A VBA version of the code sample is available [[Transfer_Data_to_the_Synthesis_Data_Warehouse_(SDW)/VBA|here]]. 

 '''VB.NET'''
 
 {{APIPrefix|Imports}} SynthesisAPI 
 {{APIPrefix|Imports}} Microsoft.Office.Interop.Excel
 
  {{APIPrefix|Public Module}} Module1
      {{APIPrefix|Sub}} Main()
 
      {{APIComment|'Declare a new RawDataSet object.}}
        {{APIPrefix|Dim}} DataCollection {{APIPrefix|As New}} RawDataSet
  
      {{APIComment|'Name it "New Data Collection," and then specify that}}
      {{APIComment|'it is for use with Weibull++.}}
        DataCollection.ExtractedName = {{APIString|"New Data Collection"}}
        DataCollection.ExtractedType = RawDataSetType.Weibull
 
      {{APIComment|'Declare a RawData object.}}
        {{APIPrefix|Dim}} Row {{APIPrefix|As}} RawData
  
      {{APIComment|'Open the Excel file. The following code assumes that the}}
      {{APIComment|'Excel file is saved in the C drive.}}
        {{APIPrefix|Dim}} Excel {{APIPrefix|As New}} Application
        {{APIPrefix|Dim}} Workbook {{APIPrefix|As}} Workbook
        {{APIPrefix|Dim}} Sheet {{APIPrefix|As}} Worksheet
 
        Workbook = Excel.Workbooks.Open({{APIString|"C:\SampleData.xlsx"}})
        Sheet = Workbook.Sheets(1)
 
      {{APIComment|'Read each row of data in the Excel file.}}
        {{APIPrefix|Dim}} i {{APIPrefix|As}} Integer, MaxRow {{APIPrefix|As}} Integer
        MaxRow = 20
  
        {{APIPrefix|For}} i = 2 {{APIPrefix|To}} MaxRow
            Row = {{APIPrefix|New}} RawData
 
           {{APIComment|'Set the properties for the current data point.}}
             Row.StateFS = sheet.Cells(i, 1).text
             Row.StateTime = sheet.Cells(i, 2).value
             Row.FailureMode = sheet.Cells(i, 3).text
 
           {{APIComment|'Add the current data point to the data collection.}}
             DataCollection.AddDataRow(Row)
        {{APIPrefix|Next}} i
 
      {{APIComment|'Close the Excel file.}}
        Workbook.Close()
        Excel.Quit()
 
      {{APIComment|'Connect to a Synthesis repository.}}  
        {{APIPrefix|Dim}} MyRepository {{APIPrefix|As New}} Repository   
        MyRepository.ConnectToRepository ({{APIString|"C:\RSRepository1.rsr11"}}){{APIComment|'Replace with name and path to test repository.}}
 
      {{APIComment|'Send the data collection to the repository.}}
        MyRepository.DataWarehouse.SaveRawDataSet(DataCollection)
 
      {{APIPrefix|End Sub}}
 {{APIPrefix|End Module}}

==Discussion==
Begin by creating an SDW data collection. The [[RawDataSet Class|RawDataSet]] class represents the data collection. For this example, we've set it to contain data sets for Weibull++. 

 {{APIComment|'Declare a new RawDataSet object.}}
   {{APIPrefix|Dim}} DataCollection {{APIPrefix|As New}} RawDataSet
  
 {{APIComment|'Name it "New Data Collection," and then specify that}}
 {{APIComment|'it is for use with Weibull++.}}
   DataCollection.ExtractedName = {{APIString|"New Data Collection"}}
   DataCollection.ExtractedType = RawDataSetType.Weibull

Next, declare a [[RawData Class|RawData]] object, which represents a single data point. We will use this object to represent each row of data in the Excel file.

 {{APIComment|'Declare a RawData object.}}
   {{APIPrefix|Dim}} Row {{APIPrefix|As}} RawData

The following section of code demonstrates one way to extract a row of data from the Excel file. First, the code opens a connection to the Excel file and specifies the active sheet (in this case, Sheet1). Then <code>For i = 2</code>, it creates a new <code>RawData</code> object and uses the values in row #2 of the Excel file to define the data point.

After the code finishes reading the row of data, it adds the data point to the data collection. When the code reaches <code>Next i</code>, it increases <code>i</code> with 1 and jumps back to the <code>For</code> statement, which creates a new <code>RawData</code> object to represent the data point in row #3 of the Excel sheet, and so on. The loop continues until <code>i</code> reaches the specified number of rows (MaxRow).  Finally, the code closes the connection to the Excel file.

 {{APIComment|'Open the Excel file. The following code assumes that the}}
 {{APIComment|'Excel file is saved in the C drive.}}
   {{APIPrefix|Dim}} Excel {{APIPrefix|As New}} Application
   {{APIPrefix|Dim}} Workbook {{APIPrefix|As}} Workbook
   {{APIPrefix|Dim}} Sheet {{APIPrefix|As}} Worksheet
 
   Workbook = Excel.Workbooks.Open({{APIString|"C:\SampleData.xlsx"}})
   Sheet = Workbook.Sheets(1)
 
 {{APIComment|'Read each row of data in the Excel file.}}
   {{APIPrefix|Dim}} i {{APIPrefix|As}} Integer, MaxRow {{APIPrefix|As}} Integer
   MaxRow = 20
  
   {{APIPrefix|For}} i = 2 {{APIPrefix|To}} MaxRow
       Row = {{APIPrefix|New}} RawData
 
     {{APIComment|'Set the properties for the current data point.}}
       Row.StateFS = sheet.Cells(i, 1).text
       Row.StateTime = sheet.Cells(i, 2).value
       Row.FailureMode = sheet.Cells(i, 3).text
 
     {{APIComment|'Add the current data point to the data collection.}}
       DataCollection.AddDataRow(Row)
   {{APIPrefix|Next}} i
 
 {{APIComment|'Close the Excel file.}}
   Workbook.Close()
   Excel.Quit()

Now that we've filled the data collection with the data points, the next step is to send the data collection to the Synthesis repository.
 
First, connect to a Synthesis repository (for details, see [[Connect_or_Disconnect_from_a_Synthesis_Repository|this tutorial]].)  

 {{APIComment|'Connect to a Synthesis repository.}}
   {{APIPrefix|Dim}} MyRepository {{APIPrefix|As New}} Repository
   MyRepository.ConnectToRepository({{APIString|"C:\RSRepository1.rsr11"}}){{APIComment|'Replace with name and path to test repository.}}

Then use the [[Repository.DataWarehouse.SaveRawDataSet|Repository.DataWarehouse.SaveRawDataSet]] method to save the data collection to the Synthesis repository, as shown below. 

 {{APIComment|'Send the data collection to the repository.}}
   MyRepository.DataWarehouse.SaveRawDataSet(DataCollection)

To verify that the data were imported, launch Weibull++, open the SDW ('''Home > Synthesis > Synthesis Data Warehouse''') and then select the new data collection. (To view the data, you may need to display the StateTime, StateFS and FailureMode columns by right-clicking a column header and choosing '''Select Columns'''.) 

==Notes==
In a secure database, you must have the "Create/edit/delete SDW data collections" permission in order to send a data collection to the database.

A data point (i.e., [[RawData Class|RawData]] object) for a Weibull++ data set typically requires the following properties:
* LastInspectedTime
* NumberinState
* StateFS
* StateTime 

For an RGA data set, the properties are:
* LastInspectedTime
* StateFS
* StateTime
* TopLevelSerialNumber
