The present invention extends to methods, systems, and computer program products for partitioning modeling platform data. Embodiments of the invention facilitate partitioning modeling platform data into nested horizontal slices. Using nested horizontal slices makes the modeling platform data more manageable and permits modeling platform data to align with existing tools and processes. Schemas and tables can be used to partition modeling platform data vertically and folders can be used to partition modeling platform data horizontally. Thus, a user-interface can preset the intersection of folders and schemas/tables as navigable chunks of data compatible with existing tools and processes, such as, for example, software development tools.
