Database naming rules

The rules for database naming include: easy to understand and remember: the name clearly describes the purpose of the table. Be short and clear: include only necessary information. Unique and consistent: Each table name is unique in the database and follows the naming convention. Avoid special characters: prevent syntax issues. Case sensitivity: Some systems are case sensitive.

Rules for database naming

Principles:

• Easy to understand and remember: The name should be descriptive so that users can easily understand the purpose of the table.
• Short and clear: Keep the name short and contain only the necessary information.
• Unique and consistent: Each table name should be unique within the database and follow a consistent naming convention.
• Avoid using special characters: Special characters (such as spaces, dashes, and underscores) can cause syntax problems.
• Case sensitivity: In some database management systems, table names are case-sensitive.

Specific rules:

• Table name:

  • can be used Letters, numbers and underscores.
  • The plural form should be used to indicate that it contains multiple records.
  • For example: customers, orders

• ##Field name:

  Letters, numbers and underscores can be used.
  • The singular form should be used to represent a single data value.
  • should be descriptive and reflect the content of the field.
  • Avoid using abbreviations or vague names.
  • For example:
  • customer_id, order_date
• ##Foreign key name:
  usually starts with the
  fk_
  • prefix, followed by the referring table name and the referenced field name. For example:
  fk_customer_id
##Index name:

• usually starts with

  idx_
  Starts with the prefix, followed by the table name and index column name.
  • For example: idx_customer_name
  ##Best Practice:

Use Camel case (for example: customerID

) or underscore case (for example:

customer_id
• ). For large databases, consider developing a naming standards document. Consider the relationships and data flow between tables when naming.
