Systems and methods for linking data entries in database systems

A method comprising:

• partitioning a cloud computing database according to a polymorphous data schema, wherein the cloud computing database comprises:
• a primary table dedicated to storing information applicable to a plurality of project units that may be temporarily applied to any of a plurality of projects;
• and
• a first project bucket dedicated to storing information applicable to only a first project of the plurality of projects, wherein the first project bucket comprises a secondary table;
• wherein the secondary table is a dependent table;
• identifying a first data entry stored on the primary table, wherein the first data entry comprises information regarding a first project unit to be utilized in association with the first project;
• linking the first data entry stored on the primary table to the secondary table by generating a project linkage, wherein the project linkage comprises a foreign key dependency enforcing a link between the primary table and the secondary table;
• and
• restricting a user from removing the first project unit from the first project without first breaking the project linkage for the first data entry;
• wherein the project linkage comprises a mapping stored on the secondary table that points to the first data entry stored on the primary table.
