How The Properties of Database Influence WeChat? [8], [9], [11],[12]
Database has influence WeChat apps in many ways. This is because database play important role in application for managing the organization, storage, access, security and integrity of data in a structure database. There are few important properties that influence WeChat too.
1. Data can be shared in Wechat. WeChat is a social share which allows users to share some interesting data with their friends. It allows users to send images, video, location, name card, voice call, video call, walkie-talkie and emoticons too. It is creative way to sharing and spread information to friends which brings multimedia more interactivity. For example, we can share our photos using Moments. Other friends from WeChat can view the pictures. We can also set visibility of photos we sharing and call people whom we had like to alert to our posts. We can also show that whether we like our friends' photos and comment on the photos or just tap on a comment to reply directly to it.
2. Redundancy can be reduced in WeChat because the data is integrated and redundancy is controlled in the application which can be reduce duplication of the data and saves the storage space also. In the file system, each application has its own private files, which cannot be shared between multiple applications. This can often lead to considerable redundancy in the stored data, which results in wastage of storage space. We can inviting our friends to participate in a WeChat using QR codes. To open a chat group we will have the option using the icon top right of the QR code for the chat. This code we can save, e-mail or share it with other contacts. So, redundancy can be reduce by scanning QR code in WeChat.
3. Inconsistency can be avoided in WeChat. Data consistency will occur when similar data is kept in different formats in two different files. For instances, we can access the "Favourite" option on our chat screen to save pictures, voice chats, videos and text messages directly in another files called favourite. It can make replication of data properly that helps us to forward that favorite message to other friends. WeChat can reduce the risk of loss of the data when we saved as a favourite message. We can clear the chat history but it won't detect our favorite message that we saved because its stored in another location (Favourite location). The data is stored in different files of WeChat and ensures consistency and can reduce the storage.
4. Integrity is maintained in WeChat by the use of integrity constraints. Data integrity is normally enforced in a database system by a series of integrity constraints of rules. Three types of constraints are inherent part of the relational data model which are entity integrity (primary key), referential (foreign key) and domain integrity. For example, WeChat ID is a unique name that friends can search for find us in WeChat. WeChat name is a primary name shown to other WeChat users.
Other than that, WeChat team develop and maintain the WeChat Service Accounts and Subscription Accounts on the database. For example, users are allowed to modify or delete such items in the database of the application. If they want to delete the conversation or a video, they can select the data and delete.
5. Transaction involves also influence in WeChat. Transaction is a logical unit that is independently executed for data retrieval or updates. WeChat team are always update their application version. They updated the apps with new features of the data. Transaction also happens when cashless transaction can be made by scanning a WeChat specific QR code provided by vendors. The application allows users to send voice messages, photos and other media the way they might send text messages. WeChat does all back-end technical integration and support for the vendors, including page design and payment linkups. Transaction concepts ensure security and integrity protection in case of system failure.
