Detailed Description

Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood that the description is illustrative only and is not intended to limit the scope of the present disclosure. In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present disclosure.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The terms "comprises," "comprising," and the like, as used herein, specify the presence of stated features, steps, operations, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.

All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art unless otherwise defined. It is noted that the terms used herein should be interpreted as having a meaning that is consistent with the context of this specification and should not be interpreted in an idealized or overly formal sense.

Where a convention analogous to "at least one of A, B and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B and C" would include but not be limited to systems that have a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.). Where a convention analogous to "A, B or at least one of C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B or C" would include but not be limited to systems that have a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.).

In the process of implementing the present disclosure, the inventor finds that for a scene with a high requirement on the effectiveness of data update, for example, real-time data is displayed on a large screen, due to a manner of pulling data at a fixed time in the related art, transient data loss may be caused due to a pulling period and a network delay of requesting data, and although such an influence may be reduced by a manner of shortening the pulling period, the data is updated in real time in a visual effect, but the essence of the data is a non-real-time data updating manner, so that the effectiveness of data update using the related art is not high, and the scene requirement with a high requirement on the effectiveness of data update is difficult to meet.

In order to solve the above problems in the related art, the inventors found that the reason for the short data loss is the pull cycle interval and the network delay of the requested data, so if the time consumed by the pull cycle and the network communication can be reduced as much as possible, the effectiveness of data update can be improved, and the scene requirement with high requirement on the effectiveness of data update can be satisfied.

Based on this, the inventor proposes a scheme for implementing data update based on a data push manner, and a system for implementing the scheme includes an application system server and an application client, that is, the embodiments of the present disclosure provide a data update method and apparatus, and an application system server capable of applying the method.
