It is often encountered in the computer field (software), what does the relationship do? The English is called "relation" related to the meaning of contact. I feel that translation is "Contact" is easier to understand. One-to-one, one-to-many, multi-to-many relationships of database technology, and some people define data structures - data and relationships with each other. What is the meaning of this relationship? Translation as "Contact" is more appropriate? In fact, it is white, this "relationship" can be understood this way, such as the relationship is said that there is some connection between A and B. When we need, we can find B from A. We do actually handle data, but we must first find data, the way to find the way and the relationship between the data. Linear relationship, . Description A and B have a relationship, B and C have a relationship, C and D have a relationship. Thinking so much, I wrote it down and prevent forgetting to turn over the database textbook and think of it. "Relationship" in the relational database is a specified linear relationship. Squiring the various relationships in the real world into their respective linear relationships. Use the relationship to express a wide variety of relationships. Ok, happy
