                                 Hide the confidential content of databases: 
                                In most projects, IT companies give developers access to a test environment that contains a copy of their customer's database. In case you need to give your developer access to a database, but you prefer that some data remains invisible for your developer, Campion-Tech provides 
(these SQL scriptst), which you can run on the target database to hide the confidential part of its contents. 
                               
 Example:
                                After executing the script 
(secure-odoo-12-entreprise-edition.sql), the emails of the customers will be replaced by the word "Client" concatenated with the identifier of the customer in the database concatenated with the word "@test-environment.com". 
                                
                                
                                        Before:
                                        
                                        
                                 
                                 
                                         After:
                                        
                                        
                                 
                                
                                    In the same way 
(these SQL scripts) edit any other contents of the database (phone, bank account , password, names, ....). So, you can download, edit and execute it depending on what you want to hide. In this way you can provide your developer with a test environment that is as close as possible to the production environment of your end customer, while preserving the confidentiality of your data.
