Embodiment Construction

[0055] In the following description, many technical details are proposed in order to enable readers to better understand the application. However, those skilled in the art can understand that the technical solutions claimed in this application can be realized even without these technical details and various changes and modifications based on the following implementation modes.

[0056] Explanation of some concepts:

[0057] Bitmap: Bitmap refers to a data structure that is a collection of multiple bits.

[0058] Subject: The entity around which the calculation is based. All calculations are based on the subject, such as user ID, product ID, policy ID, etc.

[0059]Continuous operator: An operator used to count the continuous situations in which the subject executes or triggers an action, we call it a continuous operator. For example, in the example of asking for the maximum number of consecutive days a user has logged in, the subject is the user ID, and the triggered action ...

Abstract

The invention discloses a data query and storage method and system. The data storage method comprises the steps that when an agreed event is triggered, a bitmap is read from a storage device, each bitmap is used for storing information that the agreed event is triggered within a period of time, and each bit in the bitmap corresponds to whether the agreed event is triggered or not within an agreedtime; the position of a bit needing to be operated in the bitmap is calculated according to the time when the agreed event is triggered, and the bit of the position in the bitmap is set as a value representing that the agreed event is triggered; and the modified bitmap is written back to the storage device to replace the bitmap before modification.

Description

technical field [0001] This specification relates to computer data storage technology. Background technique [0002] At present, in order to increase the daily activity of products and enhance user stickiness, the following application scenarios are often encountered: merchants need to collect information about users’ continuous execution of a certain action, and then formulate different strategies for promotion or marketing based on the statistical information. For example: according to the number of consecutive logins of the user, a different number of points will be presented. Users who log in for 7 consecutive days can obtain VIP trial privileges, and users who log in for 10 consecutive days can obtain discount coupons for a certain product, etc. [0003] However, in the traditional solution, a check-in record corresponds to a piece of data (such as a record in a database, or a line of data in a log file), and this piece of data includes information such as the identity ...
