Abstract: The present invention refers to the field of transactional data management. The invention provides a transactional semantic concurrency control system for managing a database, wherein the system comprises a data store engine which is adapted to manage the database comprising value rows, and each value row comprising a primary key uniquely identifying each row, at least one semantic column and a commit timestamp; wherein the data store engine is further adapted to manage operation rows, which are rows comprising a primary key, at least one operation to be applied over at least one semantic column of a value row identified by the primary key, and a commit timestamp; store the value rows and the operation rows; generate an operation row when it receives an operation that inserts, updates, upserts, and/or deletes a row of the database with the commit timestamp of the operation; and apply the operations of at least one operation row when a trigger condition is satisfied.

Abstract: Hinge for furniture, comprising at least one pair of leaves (6-7) mounted in a transverse housing in a supporting profile (1) by means of parallel independent rotation pins (14), which extend through the knuckles (9) of the leaves, said knuckles being equipped with teeth (18), parallel to the rotation pins (14), which mesh with one another.

Abstract: Hinge for furniture, comprising at least one pair of leaves (6-7) mounted in a transverse housing in a supporting profile (1) by means of parallel independent rotation pins (14), which extend through the knuckles (9) of the leaves, said knuckles being equipped with teeth (18), parallel to the rotation pins (14), which mesh with one another.
