UpgradePerCompany	Provides instructions for upgrading data in a business data table. When you perform a data upgrade, these methods are run for all companies in the database, where each method is executed within its own system session on Dynamics 365 Business Central service that connects to the specific company. You typically use this type of method when the data in the table that you upgrading is company-specific, as specified by the table's DataPerCompany Property.
UpgradePerDatabase	Provides instructions for upgrading data in a business data table. These methods are executed once during an upgrade process, in a single system session on Dynamics 365 Business Central service that does not open any company. You typically use an UpgradePerDatabase method when the data in the table that you are upgrading is not company-specific. This can prevent locking issues when upgrade methods are run in parallel mode.
TableSyncSetup	Provides instructions about how to synchronize the table schemas in the business database with the table definitions.
CheckPrecondition	Provides logic that checks conditions that must be met in order for the data upgrade process to continue and start running the Upgrade methods.
