Abstract: Bands for wearable devices include multiple band retainers used to maintain engagement between an assembly (e.g., a pair) of bands. Some band retainers may be permanently affixed with the band at a certain location of the band, while other band retainers can be removable. The removable band retainers can be moved to different locations of the band, thus allowing the band retainer to retain another band at different locations. As a result, the assembly of bands can be used with different users, and in particular, users with different wrist sizes. Moreover, using multiple band retainers can provide an engagement force between the bands to withstand higher-impact events, such as swimming and diving. Additionally, bands and band retainers may include one or more liquid-resistant and corrosion-resistant materials.

Abstract: The present disclosure provides a method for interconnecting a data lake and a relational database, including the following steps: S1: adding a data source class of a relational database to a data lake; S2: matching and using, by the data lake, a data source class of the relational database; and S3: determining and loading a corresponding driver according to the data source class, so as to connect the corresponding relational database. By cascading a data source registering configuration file, a relational database configuration file and a driver package catalog in a parameter passing method, when the data lake is started, a specific database to be used is designated unnecessarily, but a corresponding database is used directly. The configuration file is also traversed unnecessarily, but the user acquires configuration information as required in the parameter passing method.
