BLOBs (Binary Large Object) are files such as images, icons, HTML pages, Office documents and other media files. There is no type restriction. All BLOBs required by the application are stored in the database. These are both user interface BLOBs (e.g. symbols for commands and functions) and user data BLOBs (e.g. documents or drawings) that are to be managed, processed or made accessible to users by the application. BLOBs are referenced and displayed directly in dialog fields.
The client always accesses the local BLOB cache first, meaning that resources of the same name are not automatically updated, e.g. after a server upgrade. If the local cache is emptied, all required images are loaded directly from the server and updated in the BLOB cache.
JustRelate CRM offers the Clear BLOBs function in the Extras menu. It allows you to empty the local cache if icons and other graphic elements are not displayed correctly anymore in the client, or if the server was updated.
