How do you optimize the performance and security of your OpenERP database when using multiple languages?

To optimize performance and security of an OpenERP database with multiple languages, regularly update and maintain indexes for efficient querying, and ensure strict access controls and encryption for data security, particularly for language-related tables and fields.

In a global corporation using OpenERP, setting English as the default language for consistency, and strategically choosing fallback languages like French, Mandarin, and Spanish ensures smooth navigation. Thorough user testing minimizes user confusion, and enabling translations for user interface terms is found to have a minimal performance impact. Continual monitoring and adaptation of language settings facilitate optimal multilingual support and user satisfaction.

In version 16 of Odoo a major refactoring of the translation system took place, now the translation is directly stored in the same record as the source term as a JSONB. If you experience performance issues related to translation and are on an older version consider upgrading.

This paragraph is completely false. First there is no default or "backup" language for the system. What you can configure is the default language when you create a new user or contact. For that enter the debug mode and go in settings > technical > actions >User-defined Defaults. There you can redefine the "language (contact)" default code with the language code of your choice. There is also no option to deactivate ui translation. Some text fields are translatable tough, like the name of the contact tags. You will see a little button (EN if you're in english) at the right of the input box. You can click on it to display and edit the translation of all the installed languages for this tag's name.

Not quite! To configure language settings in Odoo, navigate to Settings > Translations > Languages, where you can manage language configurations such as activation, naming, codes, and formatting for dates and numbers. The General Settings menu allows adjusting module features and integrations, not directly tied to language defaults or fallbacks. Modern Odoo handles translations efficiently without significantly impacting the database structure. Always back up data before making major changes.

For optimal Odoo performance, design efficient queries by specifying only needed fields instead of using `SELECT *`, reducing database load. Implement indexing for commonly searched fields and use domain operators for database-level filtering, enhancing speed. Configure PostgreSQL with settings like `shared_buffers` at 20% of memory and `effective_cache_size` at 50% for better performance, and maintain regularly with tasks like vacuuming. Adjust Odoo's settings based on system resources, setting worker numbers to match CPU cores. Regularly monitor performance through Odoo's tools and PostgreSQL statistics to address bottlenecks.

For comprehensive Odoo/OpenERP system security, focus on encryption, authentication, authorization, firewall, antivirus, and backup solutions. Odoo's data security involves dedicated databases for client isolation, encryption of passwords with PBKDF2+SHA512, and secured HTTPS communications. Its open-source nature invites global community review for continuous security enhancement. Regular updates, strong password policies, role-based access control (RBAC), secure network configurations, and diligent backup and recovery planning are recommended.

For optimal database performance in Odoo, especially with multi-language support, leveraging Odoo's built-in profiling tool is key. This tool records queries and stack traces, enabling detailed analysis via the speedscope app or custom tools. It's accessible in developer mode or through Python for comprehensive insights. Additionally, effective query optimization, guided by Odoo's ORM, is crucial. It helps craft efficient queries, reducing database load and enhancing speed. Broader performance strategies include using Odoo's logging and PostgreSQL statistics, plus community modules like Odoo Profiler for in-depth performance data. These approaches ensure a swift, reliable Odoo database across languages.

To update language packs in Odoo, go to Settings, select Translations, and then Load a Translation. Here, you can choose a new language to add to your system and click on LOAD. If you want to change a user's language, navigate to Users under Settings, choose a user, and edit their preferences to select a previously installed language.
