1. A computer implemented method for maintaining immediate materialized outerjoin views, comprising: creating, using a computing device, a before image of a base table of a database; executing, by the computing device, an update statement on the base table; creating, by the computing device, an after image of the base table, wherein the after image indicates updated rows of the base table; computing, by the computing device, a delta of the base table, wherein the computing comprises comparing the before image to the after image; computing, by the computing device, a view delta of a previously defined immediate materialized view (iMV) based on the computed delta of the base table; and updating, by the computing device, the iMV using the computed delta of the iMV to reflect changes in the delta of the base table.
