Practice

Description

Development and design proposal

Database Object Naming Conventions

This practice describes the restrictions on naming database objects.

Database Object Design

This practice describes the principles for designing databases, schemas, tables, fields, constraints, views, and joined tables.

Tool Interconnection

This practice describes notes about configuring tools.

SQL Compilation

This practice describes the principles for performing DDL operations, loading and unloading data, converting types, and performing queries.

Creating and Managing Tablespaces

The administrator can use tablespaces to control the layout of disks where a database is installed. This practice describes how to use SQL syntax to create and manage tablespaces.

Creating and Managing Tables

A table is created in a database and can be stored in different databases. Tables under different schemas in a database can have the same name. This practice describes how to use SQL syntax to create tables.

Querying System Catalogs

In addition to the created tables, GaussDB contains many system catalogs. These system catalogs contain information about instance installation as well as the queries and processes running in GaussDB. This practice describes how to collect information about the databases by querying system catalogs.

Data migration

Using DRS to Migrate Data from Oracle Database to GaussDB

This practice describes how to use DRS to migrate data from Oracle databases to GaussDB.

Data backup

Configuring an Automated Backup Policy

This practice describes how to enable the system to automatically create backups for a DB instance during a backup window and save the backups based on the configured retention period.

Creating a Manual Backup

This practice describes how to create manual backups for a DB instance. These backups can be used to restore data for improved reliability.

Deleting a Manual Backup

You can delete manual backups for instances and tables to release storage space. This practice describes how to delete manual backups of an instance.

Data restoration

Restoring a Backup File to a GaussDB Instance

This practice describes how to use an automated or manual backup to restore a DB instance to how it was when the backup was created. The restoration is at the instance level.
