'''Navigation: [[User Guide]] -> Data Libraries'''


For SysCAD there are various databases or data libraries. These are typically shared by groups of projects or used by the SysCAD aplication itself.

The main database of interest is for the thermodynamic data for the compounds used in the projects. This file is called SysCAD.mdb and is located with the configuration file and is shared by a group of projects which use the same configuration (.cfg) file. 

== SysCAD Database ==

Each project will be linked to a configuration (.cfg) file and a corresponding database called SysCAD.mdb. All projects under the same project group will share the same SysCAD.mdb file.  The user may define physical and thermodynamic data for the compounds selected. The database of compounds is typically larger than the list of compounds actually used in the project. In other words you may build a database for general use and include a subset of the compounds in projects.

Data in this database can be imported from other SysCAD databases or from the distributed example database '''default.mdb''' which is located in the BaseFiles folder. If you have a legal copy of the HSC database, you can import data from this 3rd party database directly. Finally, data in the SysCAD.mdb file may be added or modified manually.

SysCAD.MDB must be located in the same folder as the .cfg file. This folder is usually named "CfgFiles", and all users must have full access rights to this folder and files.

'''Note:''' It is the responsibility of the user to check that all the thermodynamic and related data for the compounds used is correct for the full temperature range of interest.

There are two tables stored in the SysCAD.mdb file:
* [[Species Table|Species Table in 9.2]] ([[Species Table in 9.1]])
* [[Conversions Table]] (Engineering Units Conversion)
In SysCAD 9.1 there is an additional table:
* [[Solution Table]]

For information on editing the data in these see [[Editing SysCAD Database|Editing SysCAD Database in 9.2]] ([[Editing SysCAD Database in 9.1]])
