. Identifiers based on existence have the advantage of being a separate property, with a small placeholder and the same size. As long as your relational database management system (RDBMS) is supported, there is no performance disadvantage based on existing identifiers. (most RDBMS provide a valid allocation order number based on an existing identifier.) The only

group) To use ASM, you need to create an ASM instance for managing the ASM disk group. An ASM disk is composed of one or more ASM disks. An ASM disk can be an actual disk, a partition of a disk, or a logical volume managed by LVM, but must be an unformatted raw device. The size of the ASM disk group is the total size of the ASM disk in the group. The available capacity varies depending on the fault tolerance level. 5. ASM instance and RDBMS instance

between attributes when merging the attribute collection (entity). The entity-dominant type starts by looking for a meaningful entity to apply to the database, and then defines the entity by defining the attribute. The entity-Dominant design method should be used when the number of entities in the real world is below 1/10. Object-oriented database design is based on object model, which belongs to entity-or
