Abstract: Data processing is disclosed in various aspects. For instance, an example method includes acquiring a plurality of objects with a sortable schema, the sortable schema specifying at least one field of the plurality of objects; determining metadata, sortable data, and non-sortable data of the plurality of objects on the basis of a value of the at least one field of the plurality of objects; and generating a serialized representation of the plurality of objects on the basis of the metadata, the sortable data, and the non-sortable data. By the method, one group of objects is converted into a serialized representation with sortable information, so that efficient object searching can be achieved without relying on an additional comparator.

Abstract: Data reads and related data reading processes are described. An example data read method includes: receiving a data read request, the data read request being aimed at target node data stored in a target node of a B+ tree; acquiring node location information, the node location information indicating a storage location of node data in a node data set of the B+ tree, and the node data set including the target node data; and determining a target storage location of the target node data. Beneficially, data stored in the B+ tree can be read and updated efficiently while reducing computing overhead.

Abstract: An epoxy resin composition comprising an epoxy resin component containing at least 5% by weight of an epoxy resin of Formula [I], an epoxy hardener, and an inorganic filler as essential constituents: ##STR1## [wherein R and R.sup.1 denote alkyl of C.sub.2 to C.sub.6, and n is an integer repetition unit from 0 to 10.]. The epoxy resin composition, when used as a molding material, is low in water absorption rate and flexural modulus (low stress).
