4. PostgreSQL Documentation by The PostgreSQL Global Development Group
PostgreSQL Documentation is the official documentation of PostgreSQL. It has been written by the PostgreSQL developers and other volunteers in parallel to the development of the PostgreSQL software.
It describes all the functionality that the current version of PostgreSQL officially supports.
To make the large amount of information about PostgreSQL manageable, this book has been organized in several parts. Each part is targeted at a different class of users, or at users in different stages of their PostgreSQL experience:
- Part I is an informal introduction for new users.
- Part II documents the SQL query language environment, including data types and functions, as well as user-level performance tuning. Every PostgreSQL user should read this.
- Part III describes the installation and administration of the server. Everyone who runs a PostgreSQLserver, be it for private use or for others, should read this part.
- Part IV describes the programming interfaces for PostgreSQL client programs.
- Part V contains information for advanced users about the extensibility capabilities of the server. Topics include user-defined data types and functions.
- Part VI contains reference information about SQL commands, client and server programs. This part supports the other parts with structured information sorted by command or program.
- Part VII contains assorted information that might be of use to PostgreSQL developers.
5. Structured Query Language (SQL): a Practical Introduction by Akeel I Din
- A Rough Guide to SQL – presents an overview of the SQL language. The major commands are described from a functional point of view.
- Creating and Maintaining Tables – starts by considering the DDL as defined by the ANSI/ISO standard. The later sections of this chapter describe how to create, alter and delete SQL tables.
- Querying SQL Tables – the method of interrogating an SQL database.
- Adding and Updating Data.
- Data Integrity – looks at the concepts used by SQL to restrict the information that can be added to the database.
- Views – introduce the reader to another database object; the view.
- Database Security – looks at the security features that are built into SQL itself and also addresses some of the wider aspects of database security.
- Transaction Processing.
- The Database System Catalog – describes the structure and content of a typical system catalog by looking at the system tables of some popular commercial SQL DBMSs.
- Embedding SQL in a Host Language – looks at the other method of using SQL, programmatic SQL.
The book is released under a free to use non-commercial license.
