A database is stored as a plurality of database shards in a distributed database grid comprising a plurality of grid elements, each including a mid-tier database system. A first grid element receives, from an application executing in the same memory as a mid-tier database system of the first grid element, a first database transaction including at least one database operation on specific data stored in a first database shard that belongs to the first grid element. The first grid element performs and commits the first database transaction without participation of another grid element of the plurality of grid elements. The first grid element receives a second database transaction that requires access to another database shard that does not belong to the first grid element. Multiple grid elements of the plurality of grid elements perform the second database transaction and commit the second database transaction using a two-phase commit protocol.

A video input device senses a visual portion of a presentation and produces video signal information corresponding to the visual portion. A user interface is provided for inputting presentation identification information relating to a presentation. The audio signal information, video signal information and presentation identification information are stored as a presentation set. The system further includes a presentation management portion in communication with the presentation capture portion. The presentation management portion includes a character recognition device for generating text character information from the presentation set video signal information and adding the text character information to the set. The presentation set is stored in a database that includes a database indexing system for generating an index of text character information from the presentation set, and a database search program for searching the index for selected information contained therein. The presentation playback portion includes an input query system for formulating and directing search requests to the database search program. An output display device displays search results following a search request. Based on the search results, users can selectively replay a presentation set from the database.
