I recently started to learn about oracle and now share my notes as follows. I. Data Dictionary Data dictionary is the most important component of the oracle database. It provides some system information of the database. Such as the height, weight, skin color, and other static information of a person. It is a set of read-only tables and views, and the owner of the data dictionary is the sys user. The data dictionary information is obtained from the data file. The user can only perform the query o

Priority questions about selectors:One of the most vivid things you can see in CSS is that he creates a priority score to measure the precedence of a selector:Tag Selector, pseudo-class pseudo-element, priority integral is 0;class Selector, attribute selector, priority integral is 10;ID Selector, priority integral is 100;The style attribute within the tag, priority integral is 1000;Other selectors, such as wildcards and so on, have priority points of

that, in layman's terms, the object is dynamically generated based on the given class name (string mode). This way of programming allows an object to determine exactly which object it is when it is built. The application of reflection is very extensive, many mature frameworks, such as Hibernate in Java, Spring Framework. NET in the NHibernate, spring.net framework is the "reflection" as the most basic technical means.Reflection technology actually appeared very early, but it has been neglected

Features of the Java language (develop the habit of frequently viewing Java online help documentation) (1) Simplicity: Java is a new type of computer language simplified and improved on the basis of C and C ++ computer languages. It removes the pointers that are most difficult to correctly apply

now is not the　　ConstantThere are several types of constants. Constants for each type have a data type constant: integer constant character const floating-point constant enumeration constant 1. Integer constants consist of a string of numbers if it starts with the number 0, then 8 is the binary, otherwise 10 octal constants do not contain 8 and 9 digits starting with 0x or 0X are 16, and the 16 binary cont

for float and double, the actual precision (determined by the actual hardware and operating system) is used by default. Otherwise, the precision is rounded down. When decimal does not specify the precision, the default integer is 10, and the default decimal point is 0. Decimal is usually used to indicate data with high precision such as currency. The TIMESTAMP type is 4 bytes, stored in numeric value, displayed as "YYYY-MM-DD HH: MM: SS" if the curr
