General information

Abstract

AppUpIn5 is a tool-app for OSBP applications. It creates all models necessary for an OSBP app to be able:

• to import a CSV-file into a database
• to generate a complete application to process that data
• to export any modified data back into a CSV-file.

This is the introduction to this app.

OSBP applications

The OSBP application My1App should already have been generated before starting this app. You can find the instructions here.

CSV-file

At least one CSV-file needs to have been prepared in advance for model expansion and data import. We use Articles.csv as the example. Please remember where you've saved your CSV-file, as it will be used to create the models and import the data.

Here is an example of a vlaid CSV-file:

AppUpIn5

Preparation

Before starting the app, you need to perform the following steps from within Eclipse:

1. Change the Text file encoding to UTF-8 in Preferences -> General -> Workspace. Click on Apply.
   
   
   
   
   
   
2. In Preferences -> OSBP Application Configuration, change the Product Configuration from workspace to the name of the OSBP project which you want to use, in this case org.osbp.my1app.product. Please note that your entry will not be saved. You will need to perform this step every time you reopen Preferences.
   
   
   
   
   
   
3. In Preferences -> OSBP Application Configuration -> PersistenceUnits, copy to the clipboard the PersistenceUnit name associated with your CSV-file, in this case businessdata.
   
   
   
   
   
   Paste this value into the field Persistence unit to use in entity in Preferences -> OSBP CSV2APP.
   
   
   
   
   
   
4. Configure all DSL model paths which will be modified after running this app. These models can be found in the model directory of the OSBP Project, in this case org.osbp.my1app.model.*/models/:.
   
   
   • We shall use the Entity model as the example:
     
     
     1. Click on Browse...
        
        
        
        The Entity model is the file my1app.entity, which can be found in org.osbp.my1app.model.core/models/.
        
        
        
        
        
        
        
        
     2. Click on the file name and then click on Open.
        
        The configuration of the Entity model is now complete.
        
        
        
        
        
        
   • All other models can be configured in the same way as the Entity model:
     
     • the DTO model is the file my1app.dto, which can be found in org.osbp.my1app.model.core/models/.
       
     • the DataInterchange model is the file my1app.data, which can be found in org.osbp.my1app.model.datainterchange/models/.
       
     • the Datamart model is the file my1app.datamart, which can be found in org.osbp.my1app.model.datamart/models/.
       
     • the Table model is the file my1app.table, which can be found in org.osbp.my1app.model.table/models/.
       
     • the UI model is the file my1app.ui, which can be found in org.osbp.my1app.model.ui/models/.
       
     • the Dialog model is the file my1app.dialog, which can be found in org.osbp.my1app.model.dialog/models/.
       
     • the Perspective model is the file my1app.perspective, which can be found in org.osbp.my1app.model.perspective/models/.
       
     • the Menu model is the file my1app.menu, which can be found in org.osbp.my1app.model.menu/models/.
       
     • the Action model is the file my1app.action, which can be found in org.osbp.my1app.model.action/models/.
       
     • the Authorization model is the file my1app.authorization, which can be found in org.osbp.my1app.model.authorization/models/.
       
       
   • The configuration of all models is now complete. Click on Apply.
     
     
     
     
     
     
5. Change the delimiter to use as is appropriate for your CSV-file. Click on Apply to confirm. In this example, we change it to ;.
   
   
   
   
   
   
6. Click on OK to close the Preferences window.
   
   
7. Find your CSV-file, click on it and drag it to the Eclipse workspace.
   
   
   
   
   
   
   • The CSV-file looks like this in Eclipse:
     
     
     
     
     
     

Create DSL models

1. At the top-right corner of the CSV-file, there is a button Create App. All DSL models based on this CSV-file are automatically generated by clicking on this button.
   
   
   
   
   
   
   • When you click on the Create App button, no status indicator is displayed. If you want to know the progress of the model-creation operation, please check the bottom-right corner of Eclipse, or open the Progress window.
     
     
   • Please note that no data are automatically imported, only data models are created in this step.
     
     
     
     
     
     
2. When the workspace has finished being built, you can check the models that were configured in the previous step. They should all have been modified according to the CSV-file.
   
   
   • In the entity model, the new entity Articles is generated. The entity name is the name of the CSV-file, and all attributes are defined according to the column names contained in the CSV-file.
     
     
     
     
     
     
   • In the dto model, a new dto, ArticlesDto, is generated based on the new entity.
     
     
     
     
     
     
   • In the ui model, a new ui, Articles, is generated based on the new dto.
     
     
     
     
     
     
   • In the action model, two new toolbars, Articles_dialog and Articles_table, are generated. They will be used in the new dialog and table.
     
     
     
     
     
     
   • In the datamart model, a new datamart, Articles, is generated for the new entity.
     
     
     
     
     
     
   • In the table model, a new table, Articles, is generated for the new datamart.
     
     
     
     
     
     
   • In the dialog model, a new dialog, Articles, is generated based on the ui and action models.
     
     
     
     
     
     
   • In the authorization model, a new row is added for the new entity.
     
     
     
     
     
     
   • In the perspective model, a new perspective, Articles, is generated for the new table and new dialog.
     
     
     
     
     
     
   • In the menu model, a new menu, Applications, is generated in which entry Articles is defined for the new perspective.
     
     
     
     
     
     
   • In the datainterchange model, a new datainterchange, Articles, is defined. The path to the CSV-file is saved here, which is very important for the data import. If you move the CSV-file to a different location, please do not forget to change the path here, as well.
     
     
     
     
     
     

Import data

Data can be imported once the OSBP application has started.

1. Start My1App in Eclipse.(How to start My1App).
   
   
2. Copy this URL into your browser:
   http://localhost:8081/my1app
   
   
3. Enter the user name and password on the Login screen, e.g., Admin, Admin, choose to remain logged in and then click on Login.
   
   
   
   
   
   
4. Click on the menu list. You can see at the end of the list that a new entry, Applications, has been generated.
   
   
   
   
   
   
5. Expand this entry and click on Articles.
   
   
   
   
   
   
6. Near the top-left of the window, click on the first button to import the data.
   
   
   
   
   
   
7. Wait for a few seconds; you can then see that all data in the CSV-file have been imported.
   
   
   
   
   
   

Extensions 1.0

In this section we describe the new functionalities we are currently working on, which will be available up to the next release version.

Although it is possible to read and import data from csv files, the reading process doesn’t yet consider possible existing relations between the data contained in those files. With the next release version, it will be possible to enrich csv files with the metadata information needed, to highlight the presence of relations between the flat data contained in a bundle of different csv files. Thus, giving users the means to set up information over more complex structures.

You can find more information about it here.
