graph G is a strong connected graph, otherwise known as non-strong connected graph.If G is a non-strong connected graph, the strongly connected sub-graph is called the strong connected component of G.Meaning of "great": Refers to the sub-graph and then increase the other vertices in Figure g, the child diagram is no longer connected.Spanning treeSpanning tree: The spanning tree of a connected graph (undirected graph) is a minimal connected sub-graph that contains all n vertices in the graph and

connected to two neatly arranged icons, the line is drawn as a series of segments connected at right angles. This format is the most commonly used in this book. With care, the most line crossings can avoided. If a line crossing is necessary and there was ambiguity about what the paths is connected, a small arc can used to Indic Ate a line crossing.Note that most of the lines can be avoided by crossing. If a crossover line is unavoidable, there is ambiguity as to how the path is connected. A sma

In order to obtain "common language" with you, the following concepts and terminology are given a definite meaning.1, data: the symbol of the objective thing, in the computational science, all the symbols can be entered into the computer and processed by computer programs collectively.2. Data element: is the basic unit of data, which is usually considered and processed as a whole in computer programs. A dat

Data warehouse is basically read-only, reflecting the content of historical data, the collection of database snapshots at different points in time, and the data derived from the statistics, synthesis, and reorganization of these snapshots, rather than the data of the OLTP system it involves operations that are primarily query operations, Users cannot delete or update them. Once the data has exceeded the data storage period, the data will be deleted from the current Data warehouse.4 O'Clock Tran

This article describes some of the basic and most important terms of Docker: Image: Mirroring is the cornerstone of building the Docker world, where users create containers based on images, a layered structure based on a federated file system, built by a series of instructions. It is easy to understand that mirroring is the program code that a container runs. Registry: Docker uses Registry to save user-built images. Registry is divided into p

Participant (player)The decision-making body involved in gameActors (Actions)For each participant, he can take action (strategy) of the whole composition of the set. The state of being formed after each participant's respective action is called the situation (outcome)Revenue (payoff)The benefits to be gained by each participant in different situations.

in a service that is used in a given system.Tagged values is placed in a note attached to the affected element, as shown in Figure 6-7. Each tagged value comprises a string that includes a name (the tag), a separator (the symbol =), and a value (of the tag).The label value is placed in the note, and the note is attached to the component it affects. As shown in 6-7. Each tag value consists of a string that contains a name (label), a delimiter (symbol =), and a value (the label).Note One of T

When the CI framework was first used, it was intended to write a series of CI-source reading notes, which, unfortunately, had not been acted on. Recently there are few projects, and finally there is some time to write something. Then prepare to record some of the previous notes and experience, on the one hand, the right to make a memo, on the other hand remind yourself: learn from learning and have a way out, forget the past means betrayal!

Introduction to the first chapter 1.1 What is a data structure The main content of data structure research: The data structure is a subject of the computer operation object and the relation and operation between them in the programming problem of non-numerical computation. 1.2 Basic concepts and terminology • Data: All the symbols that can be entered into the computer and processed by the computer are comp

quotation marks (the French citation is "") and placed above the name of another component. Optionally the stereotyped element is rendered by using a new icon associated with that stereotype.Arbitrarily modeled elements can be represented by using a new icon that is linked to that stereotype.A Tagged value is a property of a stereotype, allowing the create new information in an element bearing that stereotype. Graphically, a tagged value is rendered as a string of the form name=value within a

Beginners often confuse terminology such as Oracle instances, Oracle databases, and Oracle servers.Typically an Oracle database can be divided into two parts1. Example (instance)An instance is a non-fixed, memory-based, basic process and memory structure. When the server shuts down, the instance does not exist.2. Databases (database)A database refers to fixed, disk-based data files, control files, log files
