 ===== Project Data =====
-A SIGMA **Project** (Chapter Project) is used to manage the different files which are created and needed by SIGMA. A project is a folder in the directory. Essentially it contains various processes.

+A SIGMA **Process** (Chapter [[en:erste_schritte:prozess_erstellen]]) is the basic unit to work and simulate with. It unites all required data. The most important components are:
-  * **Machine configuration** (Chapter Enter Machine Parameters and Configuration ): The machine configuration manages the characteristic properties of a concrete machine and all its elements.
+  * **Machine configuration** (Chapter [[en:eingabe_der_maschinenparameter_und_konfiguration]]): The machine configuration manages the characteristic properties of a concrete machine and all its elements.
-  * **Barrel configuration** (Chapter Define Barrel Elements): The barrel configuration defines a concrete configuration for a barrel consisting of the defined barrel elements for this process.
+  * **Barrel configuration** (Chapter [[en:eingabe_der_maschinenparameter_und_konfiguration:eingabe_der_zylinderelemente]]): The barrel configuration defines a concrete configuration for a barrel consisting of the defined barrel elements for this process.

+  * **Screw configuration** (Chapter [[en:eingabe_der_maschinenparameter_und_konfiguration:schneckenelemente]]): The screw configuration defines a concrete configuration for a screw consisting of the defined screw elements for this process.
-  * **Process parameters** (Chapter Simulation) and **Material data** (Chapter Material Data): The process parameters define the barrel temperatures and the material stages. But the concrete material data are saved in separate files so they are not integrated part of the process parameters.

-When double clicking on an item in the project explorer, a corresponding window opens up, which shows the characteristic data and allows modifying them. The machine, barrel and screw configuration can either be edited directly by clicking on the respective name or icon in the project explorer or in the dialog **Visual machine configuration** (Chapter Enter Machine Parameters and Configuration). This gives an overview of screw, barrel and machine and opens up when clicking on Machine or choosing **Configuration, Configuration editor** within the main menu. This way of changing data which are relevant to the calculation leads to a loss of the current results and the modified settings are available for a new calculation. If data are changed this way and therefore no longer correspond to the original data in the saved files, the unsaved items are marked with an asterisk (*). An exclamation mark marks faulty data. The corresponding data should be checked before the next calculation.

 ===== Process Window =====
-By activating a process, a window that contains all information about the results of this process opens up within the empty space. The  figure shows two of such **Process windows**. The process window is divided into two parts. A diagram with the current calculation results (Chapter Diagrams ) which depends on the selection made is placed above the second part a picture of the screw and the barrel configuration. Additionally process parameters (barrel temperatures and material stages) are given in textual form. So far as they are available also the experimental data (Chapter 9) are shown.

 SIGMA also allows to define so-called **Batch processes** (Chapter Create a Batch Process), which are like normal processes but they use one machine configuration with several varying process parameters. In case of a batch process the process window shows the process parameters of the base process and a graph for each variation in the diagram.

 The upper left frame contains besides the project data tab a tab called **Material**. The material data are fundamental for each calculation and therefore they should be measured and inserted very carefully. SIGMA offers the direct access to the relational database of PAM. PAM is a part of the SIGMA distribution and assists polymer engineers in administrating material data of polymers and in evaluating material parameters of series of measurements.
-The material tab itself is divided into two frames (see figure right) which show the materials (Chapter polymers, polymer blends, and filled polymers) contained in the connected database (above) and in the current project folder (below). The default database can be changed under **Options** (Chapter Options).

-If there is no database specified, a button that opens up the connect database window is available (see figure left). In this way it is possible to connect with any database. Double clicking on a material opens up the Material data window where it is possible to change the material properties. Note that there is no Ok-button. But the changes can be saved to the material or database file. To change the material data of the current process without saving the changes to the material or database file the material data window must be opened up by double clicking on the material in the project tab and confirmed by the Ok-button.
+If no database is specified, the list of materials from the database is not displayed. Instead, a corresponding message and a button for connecting to a database are shown. By pressing this button, you can connect to any database.
-A right click on one of the material lists opens up a menu that simplifies creating, changing, and deleting materials of the project folder or database. The menu also comprises items to update the lists if they were edited from the outside as well as a function to export material data files to another folder.
+When a material is activated from one of the lists in the Material Explorer, the corresponding dialog opens and the material can be edited. Please note that the material dialogs that open do not contain an OK button, since they are loaded directly from a file or a database. However, you always have the option to save the changes you have made.
+If, on the other hand, you open a material from the Project Explorer, the changes made are applied to the process by pressing OK, without saving the material.
+In addition, each of the two material lists has a context menu (right mouse button), which allows materials to be easily created, edited, and deleted. The context menus of both lists also include an option to reload the lists in case they have been modified externally, as well as an option to export materials to another storage location.
 ===== Machine Data =====
-The third tab is named **Machines** and the bottom part contains the project’s machines, screw and barrel configurations (see figure). Double clicking a machine or configuration name on this tab opens the respective editor’s windows. The upper part of the tab contains an optional machine database. Choose **Options**, **Database** for a default database; hit **Connect** on the **Machines** tab or choose **Configuration**, **Connect to database** to select a database and connect it like described in chapter Options. In contrast to the material data there is no predefined machine database. To create a machine database choose Configuration, Create database within the main menu. The window **Create machine database** opens up (see figure). Enter path and name by hitting the … button. **Connect as** ”SYSDBA” with **Password** ”masterkey” (cf. chapter Options) and contact your administrator if the connection fails.
+The third tab displays the machine data (see figure). This tab is also divided into two sections and is structured analogously to the Material Explorer. The lower section contains the machine, screw, and barrel configurations of the project directory, while the upper section contains the corresponding configurations from the connected database. If no database is connected, a Connect button is displayed, which allows a database to be selected and connected.
+Another way to select the databases for materials and machines is provided via the menu Options → Database. There, databases can also be defined that are automatically connected when the program starts.
+Unlike the material data, a database must first be created for the machine data. No database is predefined. The database can be created via the main menu under Configuration → Create Database. From there, an existing database can also be connected or disconnected.
+When Create Database is selected, the window Create Machine Database opens (see figure below). First, the database must be named. This is done by clicking the button with “…” to the right of the empty field next to Database:. Select the path where the database is to be stored and then enter the database name as the file name. At the time of creation, this name must not already exist in the selected directory. After confirming with OK, the Create Machine Database window appears again, and the fields Connect as: and Password: must now be filled in.

+Unless configured otherwise, “sysdba” must always be entered in the Connect as: field and “masterkey” as the password. After confirming with OK, the database is created.
+The Connect Machine Database window looks exactly the same as the Create Machine Database window. In this case, an existing database must be selected and no new name is specified. The fields Connect as: and Password: must again be filled in with “sysdba” and “masterkey”, respectively.
