Database(数据库):A collection of organized data that is stored and accessed electronically.
-
Table(表):A collection of related data held in a structured format within a database.
-
Record(记录):A single unit of data that is stored within a table. It represents a specific instance or entity.
-
Field(字段):A column or attribute within a table that stores a specific type of data.
-
Primary Key(主键):A unique identifier for each record in a table. It ensures that each record is uniquely identifiable.
-
Foreign Key(外键):A field in a table that refers to the primary key of another table. It establishes a relationship between two tables.
-
Index(索引):A data structure that improves the speed of data retrieval operations on a database table. It allows for faster searching and sorting of data.
-
Query(查询):A request for data from a database. It is used to retrieve specific information based on certain criteria.
-
SQL(Structured Query Language):A programming language used to manage and manipulate databases. It is used for tasks such as querying, updating, and deleting data.
-
Normalization(规范化):The process of organizing data in a database to eliminate redundancy and improve data integrity. It involves dividing large tables into smaller, more manageable tables and establishing relationships between them.
-
Backup(备份):A copy of data that is made to protect against data loss or corruption. It is used to restore data in the event of a failure or disaster.
-
Transaction(事务):A sequence of database operations that are treated as a single unit of work. It ensures that all operations within a transaction are either completed successfully or rolled back if an error occurs.
-
ACID(Atomicity, Consistency, Isolation, Durability):A set of properties that ensure the reliability and integrity of database transactions. Atomicity guarantees that a transaction is treated as a single unit of work, consistency ensures that the database remains in a valid state, isolation prevents interference between concurrent transactions, and durability ensures that committed transactions are permanent and can withstand system failures.
-
Data Warehouse(数据仓库):A large, centralized repository of data that is used for reporting and analysis. It integrates data from various sources and provides a unified view of the organization's data.
-
Data Mining(数据挖掘):The process of discovering patterns and relationships in large datasets. It involves using statistical and machine learning techniques to extract valuable insights from data.
