A Design Scheme for offline applications

of method 1 is higher than that of method 2. Method 1: Test the view to the server, and the view to indexedDB and indexedDB to the server. Method 2: Test the view to indexedDB and indexedDB to the server. So I chose method 2. Data replication Data access from a view to indexedDB is theoretically easy. In fact, there are many inexplicable points. Here we only discuss data replication. You must consider data version control. No data has been changed before replication. The local data version is t

Use SQL Server everywhere to save offline data

caching requires a low level of database functionality. Normally, some reference data is cached, and the business data is usually too large to be cached on the client. The data synchronization between offline data and the primary database is exactly what smart clients need most. However, ssev can solve these problems well. In fact, at the time of the release of SSM, mobile databases were already showing s

Answer A set of RAID volumes will rarely read all of the disk space on the physical hard disk after a long period of time, which is even more impossible. In some cases, the hard driv
