    - DatabaseConfiguration has two separate objects Production and Staging. Both objects hold the Connection strings of the staging and production database.

    $Global:StageConfigs
    StageConfigs holds the staging database credentials and details

    $Global:ProductionConfigs
    ProductionConfigs holds the staging database credentials and details

    $Global:Resources
    Resources mainly hold those configurations which should be used for the basic settings, important flags, system global paths, validation regex, URLs, or many more which can be used at system config levels

    $Global:DatabaseTable
    DatabaseTable holds all table names, Later on, we can use tables names directly at multiple places and its good practice to all are on the same place to check and also saves us from changes on multiple changes.
