Group of managers wanted to choose Oracle based technology for this that would further entrench their team and they argumented they can do it faster and cheaper than the development team.
They have already succeeded getting sizeable part of business logic implemented in PL/SQL supposedly to improve performance.
ES would make all their plans obsolete in a hurry.
Obviously, they were not interested in improving the product but in grabbing power, budget and control of the development process. Also they needed to score some points to show they accomplished something during calendar year.
Of course development team was also slow to deal with problems and overworked with other projects. This only fueled actions of database operations.
So my actions angered both managers of database operations as well as development teams.
