Software parameter management
View Patent ↗A method and apparatus is disclosed for allowing the updating and overriding of software parameters used by one or more software programs. The parameters are preferably in cache. When the system needs any such parameter, it first checks cache, then a preferably remotely located database, and then, preferably a flat file on the same computer as the cache. The checking is done in the foregoing order, and the parameter is used upon locating a current version of it. If the current version is obtained from anywhere other than the cache, it is put into cache.
1. A method comprising:
executing a software application on an application server, wherein the application software comprises a sequence of steps;
automatically monitoring the frequency of changes made to a set of predetermined parameters needed by the software application, wherein if a first predetermined parameter is updated at a frequency lower than a predetermined frequency threshold, the application server recommends to store said first predetermined parameter in a flat file on said application server, otherwise the application server advises to store said first predetermined parameter in a database of the application server;
in response of the recommendation, overriding, by the developer, the designation of storage of said first predetermined parameter from the flat file, to storage in the database;
