1. A computer-implemented method comprising: receiving, at a database server that processes Structured Query Language (SQL) queries, a request to perform a file system operation involving a link from a source resource to a target resource, wherein the source resource is stored within a repository implemented by a SQL-queriable relational database; wherein the file system operation is a file system operation that requests creation, in a file system, of a link that is of a first link type; in response to the request of the file system operation, and based on configuration information, creating a particular link that is of a second link type instead of the link that is of the first link type, wherein the configuration information includes one or more rules associated with the source resource; wherein the first link type differs from the second link type, wherein the database server performs the file system operation by accessing, in the SQL-queriable relational database, one or more link records to carry out the requested file system operation, and wherein the file system operation specifies the creation of the particular link, wherein the accessing the one or more link records includes adding a new link record to the one or more link records, and wherein the new link record identifies characteristics about the particular link.
