In this exercise, we will use the MySQL table created in Exercise 3.1 and import this information back into an empty package in MagicDraw. If not still open, launch MagicDraw with the Syndeia Tutorial Testbed.mdzip (get it here -SysML Models, Profiles and Mappings) project (alternatively, create a new MagicDraw SysML project with the Syndeia profile).
Create an empty package in the SysML model named MySQL_Tutorial Part 2. Right-click it and open the Syndeia dashboard. If Syndeia was still open from the previous exercise, right-click MySQL_Tutorial Part 1 in the Connection Manager tab and use Go to… to navigate to the new package.
Expand the component table in the Connection Manager tab to show the table contents within the database, as shown in Figure 1. Set the Connection Type to Model Transform.

Drag the table component (see red arrow in Figure 1) into the MySQL_Tutorial Part 2 package in the SysML model. Click Yes on the dialog box (Figure 2). When complete, component appears as a block in the SysML model panel as in Figure 3. Note that while the component block contains the structure of the component table (this can be seen in MagicDraw), it does not contain any of the data about specific components. This is the object of the next step.

Set the Connection Type to Data Map. Select several of the individual records under the component table in the right-hand panel. Drag them into the MySQL_Tutorial Part 2 package in the left panel. A dialog box as in Figure 4 will appear. Leave the "As Specialization" checkbox unchecked and click Yes. The new SysML instances are shown in Figure 5.

Drag more records from the component table into the MySQL_Tutorial Part 2 package in SysML, but check the "As Specialization" checkbox on the Syndeia dialog box. This will create a series of blocks that are specializations of the component block, but with the default values of the value properties showing the information from the individual records.
Create a new package in the SysML project and drag some MySQL records into it. They will still be treated as instances (or specializations) of the component block even if they are not in the same package.
In the Search Repository query box (upper right corner) of the Connection Manager, enter a valid MySQL syntax query, for example, search demo_tutorial.component where Mass < 3. Only those records satisfying the query will be displayed at the bottom of the search box and these can be dragged directly into the SysML model.
Erase the current contents of the MySQL_Tutorial Part 2 package in MagicDraw. Drag some MySQL records into it. Note that a component block is created automatically, along with the instances (or specializations) corresponding to the individual records.
In the next part of the exercise, we will make change to the data in the database and update the SysML model from MySQL.
Go to the MySQL Workbench and modify some details of the connected rows. For example, see Figure 6 where the left side shows the component table before making changes and the right side show the changes. The cost of the Communication Controller was reduced from 50 to 25 and the mass of the Payload Controller was reduced from 2.5 to 1.5.Anchor _Ref366950567 _Ref366950567 Figure 6: Modify contents of database in MySQL Workbench
Refresh the Connection Search tab by clicking Get All and multiple-select (using Ctrl key) connections DZSB01-R68 and R75 that correspond to the 2 modified rows. Right-click and select Sync Target → Source, as shown in Figure 7.

In the Containment Tree in the SysML model, you can see that the appropriate values have been updated, as shown in Figure 8.

Similarly, you can change the SysML instance slot value or block (default) value in MagicDraw and sync to MySQL by right-clicking the appropriate connection and selecting Sync Source → Target.
