	==Overview==		==Overview==

	~~The~~ SysCAD ~~species database is where the user can~~ define the thermodynamic data for chemical species ~~to be used in the~~ project. ~~The chemical~~ species ~~can be anything from~~ elemental ~~species to~~ pseudo-~~compounds~~.		SysCAD provides a Species Database used to define the thermodynamic and physical property data for chemical species within a project. These species may include elemental substances, defined compounds, and pseudo-components required for process modelling.

	~~There are two Species Database in~~ SysCAD:		SysCAD is designed as a process simulation tool and focuses on providing robust modelling capabilities. It is not intended to be a provider of chemical species property data. As such, comprehensive thermodynamic and physical property data, particularly for specialised or less common compounds, is not supplied with the software.

	#Default.93.db3 - This is the distributed main database, ~~stored~~ in the \SysCADxxx\Base files folder~~. See~~ [[SysCAD_Files#Base_Files_Folder\|BaseFiles Folder]].		Users are responsible for sourcing accurate property data from appropriate references, such as published literature, trusted databases, or experimental results, and entering this data into the Species Database. This ensures that the project database is tailored to the required level of accuracy and is appropriate for the specific application.
	#*~~This database contain some common~~ chemical species for general ~~use~~.
	#*~~We normally do not recommend editing~~ this database as it ~~will~~ be overwritten if SysCAD ~~is re-installed~~ or ~~the~~ BaseFiles ~~are updated. User specified properties will be lost if this file is overwritten~~.		Compounds that are not available in the supplied databases must be created and defined manually by the user.
	#SysCAD.93.db3 - This is the project database, ~~normally one of these files will be~~ created per project group~~. See [[~~Project Structure]].
	#*This database should contain all ~~the~~ chemical species to ~~be used in~~ the project.		There are two Species Databases in SysCAD:
	~~#*User~~ can ~~import data into this~~ database from ~~the~~ Default.93.db3, other SysCAD project databases (SysCAD.93.db3) ~~or other general~~ SysCAD format databases (e.g. NASA_Glenn_Gas.93.db3)~~. It is possible to import~~ from ~~older HSC~~ databases~~. See~~ [[Importing_Species_into_User_Species_Database#Importing_Species_from_HSC_Database\|Importing Data]].
			#Default.93.db3
			#*This is the distributed main database, located in the \SysCADxxx\Base files folder (see [[SysCAD_Files#Base_Files_Folder\|BaseFiles Folder]]).
			#*It contains a selection of commonly used chemical species for general purposes.
			#*Editing this database is not recommended, as it may be overwritten during SysCAD reinstallation or BaseFiles updates, resulting in loss of any user-defined modifications.
			#SysCAD.93.db3
			#*This is the project-specific database, typically created per project or project group (see Project Structure).
			#*This database should contain all chemical species relevant to the project, including any user-defined compounds and associated property data.

			Users can populate the project database by:

			*mporting species from Default.93.db3
			*Importing from other SysCAD project databases (SysCAD.93.db3)
			*Importing from external SysCAD-format databases (e.g. NASA_Glenn_Gas.93.db3)
			*Importing from legacy databases (see [[Importing_Species_into_User_Species_Database#Importing_Species_from_HSC_Database\|Importing Data]])
