Abstract: A computer-implemented method for performing data storage. The method comprises the steps of: receiving data to be stored from a data source; segmenting the data into immutable core objects each being written into a collection and being assigned a unique object ID; grouping the immutable objects into blobs each including at least one of the objects and being assigned a unique blob ID derived from the object ID of the at least one of the objects included therein, with the last blob of the collection being identifiable as such; defining a state of the collection by linking at least one subset of the core objects of the collection to one another with a last object of each subset being the object head of the corresponding subset and storing identification information of the head object; and storing each one of the blobs onto at least one backend.

Abstract: A soccer type game for playing in a swimming pool, the game including first and second goals formed of a material having a density sufficient to permit the goals to lie on the bottom of the pool, and a soccer type ball filled with water and also having a density sufficient to remain on the bottom of the pool.

Abstract: There is provided equipment for a game adapted to be played in an above ground pool. The game resembles the game of volleyball and includes a tethered ball which is secured by its tether to a cable stretching across the pool; the tether is free to slide along the cable.
