METHODS AND SYSTEMS FOR UPGRADING AND INSTALLING APPLICATION PACKAGES TO AN APPLICATION PLATFORM

Systems and methods for installing and upgrading application packages to an application platform. Application packages may be uploaded to a directory by developing users (developers) for installation by subscribing users (subscribers). Alternatively, a developer may send identification information to a subscribing user to allow that user to access and install that application package created by the developer. Application packages may also be upgraded. If a developer changes the original source package, a subscriber can choose to pull into their organization the change(s) made by the publisher while preserving any data rows the subscriber had created since first importing the package.
