Abstract: Techniques and solutions are described for implementing virtual table schemas. A virtual table schema includes a logical pointer that is used to target a table that includes data and is defined according to the virtual table schema. Values assigned to the logical pointer can be used to target tables at different locations, such as in-memory storage or in dynamic storage of a database management system. The dynamic storage includes an in-memory buffer cache and persistent storage. The logical pointer can be updated to point to the in-memory storage or the dynamic storage, including based on use statistics. Similarly, a table having data for the virtual table can be transitioned between the in-memory buffer cache and the persistent storage, including based on use statistics for the virtual table. A value for the logical pointer can be updated when the table is transferred between the in-memory buffer cache and the dynamic storage.

Abstract: An electronic device includes: a plurality of processing cores and a memory including a plurality of task queues respectively corresponding to the plurality of processing cores and a plurality of task relation tables respectively corresponding to a plurality of tasks. Each of the plurality of task relation tables includes: one or more entries representing a mapping relationship between an identifier of a waker task that wakes up a wakee task, and an occurrence count that is a number of times the wakee task is woken up by the waker task. At least one of the plurality of processing cores is configured to: execute a scheduler, search for a task set includes related tasks, based on the plurality of task relation tables, store a subset of tasks of the task set in at least one of the plurality of task queues, and schedule the task set.

Abstract: An electronic device is disclosed that includes a memory storing a first application run based on a first sandbox environment and a processor connected with the memory. The memory stores instructions which, when executed, cause the processor to determine whether it is necessary to change a first user identifier (UID) for the first application in response to an application installation request requesting to update the first application to a second application, assign a second UID for the second application using a UID mapping resident program based on it being necessary to change the first UID, and construct a second sandbox environment for the second application to have the second UID and a resource included in the first sandbox environment.

Abstract: An electronic device using a division permission and an operating method thereof are disclosed herein. The electronic device includes a processor or a memory storing at least one instruction executable by the processor, and when the at least one instruction is executed by the processor, the processor receives a request for installing a first application on an electronic device, acquires a division permission information corresponding to a signature permission declared by the first application, applies the division permission information to a database, installs the first application. The division permission information may be used for the signature permission on a second application different from the first application.

Abstract: Disclosed is an electronic device comprising: a memory in which instructions are stored; and a processor electrically connected to the memory. The processor, when the instructions stored in the memory are executed: acquires a command for installation of a first application signed with a first key; checks information relating to the first key in a key storage of the electronic device; if the first key is determined to be valid, installs the first application; and if the first key is determined to have been revoked, controls to prohibit installation of the first application.

Abstract: According to various embodiments, an electronic device may include: a touch-sensitive display; a processor operatively connected to the display; and a memory operatively connected to the processor, wherein the memory may store instructions that, when executed, cause the processor to: control the display to provide a right setup screen that enables a user to select data which an application is allowed to access among data stored in the memory, receive a read request for the data stored in the memory from the application, select data to be provided to the application among the data stored in the memory based on an access right policy established using the right setup screen, and provide the selected data to the application in response to the read request.

Abstract: Disclosed herein is a method for preparing an electromagnetic wave shielding material. The preparation method includes: preparing a fiber matrix; sorbing a metal salt precursor to the fiber matrix by dip coating; and bringing the fiber matrix to which the metal salt precursor is sorbed with a basic solution to oxidize the metal salt precursor such that a magnetic substance can be coated onto the fiber matrix. The method can reduce preparation costs by simplifying the preparation process through dip coating without using a high temperature process. Further, the method can also be applied to a fiber matrix which can be affected by temperature, thereby enlarging the preparation and application range of the electromagnetic wave shielding material.
