PostgreSQL

Frequently Asked Questions about PostgreSQL

• Do you design the database schema for my business?

  No. We take care of the server administration and the database engine. You are the one who will define the design and data structure that is most convenient for your project.

• What is the cost of traffic?

  It is free and unlimited. Our solution is designed to work in a private environment where the web server makes requests to PostgreSQL and we only charge for outgoing traffic.

• What is PostgreSQL?

  PostgreSQL is a free software system for managing very high-level databases, with a BSD license, compatible with any use, whether personal or commercial. It is used in business applications, data analysis, and systems that require large volumes of data. Therefore, PostgreSQL is ideal for managing structured and unstructured data, performing complex queries, and ensuring secure and efficient transactions.

• What is the difference between PostgreSQL and MySQL?

  • PostgreSQL and MySQL are open-source relational databases, but PostgreSQL offers more advanced features, such as support for complex queries, full ACID transactions, and greater compatibility with SQL standards.
  • While MySQL is often used for web applications, PostgreSQL is preferred for projects that require greater control over data and flexibility in executing advanced queries.
  • PostgreSQL has two fundamental advantages. First, in terms of its functionality and ability to work with larger amounts of data. Second, MySQL has a dual license, which means that for commercial projects, you would have to pay for its use. However, PostgreSQL has a single, fully open license for any use.

• What are the most notable features of PostgreSQL?

  PostgreSQL is a high-availability relational database system. It is capable of operating stably on the server and is therefore robust, one of the main features sought by companies. Additionally, it is consistent and fault-tolerant. It is compatible with the relational model, as it always ensures referential integrity. Some of its main features are:

  • High concurrency. It can serve many clients simultaneously and deliver the same information from its tables without locking.
  • Support for multiple data types natively. It offers the usual data types in management systems, but also many others that are not available in other competitors, such as IP addresses, MAC addresses, Arrays, configurable precision decimal numbers, geometric figures, etc.
  • Support for triggers. It allows defining events and generating actions when they are triggered.
  • Working with views. This means that data can be queried differently from how it is stored.
  • Object-relational. Another of its main features is that it allows working with its data as if they were objects and offers object-oriented mechanisms, such as table inheritance.
  • Support for distributed databases. Where working with transactions ensures that they will succeed when they have been able to be carried out on all involved systems.
  • Support for a large number of languages. PostgreSQL can work with internal functions, which run on the server, written in various languages such as C, C++, Java, PHP, Python, or Ruby. Additionally, it offers interfaces for ODBC and JDBC, as well as programming interfaces for countless programming languages.

• What advantages does PostgreSQL have over other databases?

  PostgreSQL offers several advantages, such as:

  • Support for advanced data types and complex queries.
  • Scalability and efficient handling of large volumes of data.
  • Compatibility with SQL and JSON standards for unstructured data.
  • Robust security and fault recovery features.
  • Flexibility in customization, thanks to its open-source nature.

• Is PostgreSQL suitable for large volumes of data?

  Yes. PostgreSQL is ideal for managing large volumes of data because, thanks to its scalable architecture, it can handle terabytes of data and perform operations efficiently. It also offers features such as replication, table partitioning, and query optimization to ensure adequate performance in big data scenarios.

• Does PostgreSQL support ACID transactions?

  Yes. PostgreSQL fully supports ACID transactions (Atomicity, Consistency, Isolation, and Durability), ensuring that transactions are executed reliably and securely, even in high-volume environments. This makes it an ideal choice for applications that require strict data control, such as financial or transactional systems.

• Is PostgreSQL secure for business applications?

  Yes. PostgreSQL offers robust security features that make it ideal for business applications. This includes role-based access control, data encryption in transit (SSL), certificate-based authentication, and the ability to perform audits. Additionally, it has options to enhance security through plugins and advanced configurations.
