Suitable for: Not many users, system features are not particularly complex
To add a role field to a user table, and use a field to distinguish which type of role the user belongs to
Benefits: Easy to use, little coding
Disadvantages: Management granularity is coarse, maintenance inconvenient, not flexible eno
Design Model-introduction and factory model (flat management mode VS professional manager mode), vs Professional Manager
This article will give a brief explanation of the design model, especially the concise analysis of the factory model:I. Classification of design patterns
There are five creation modes: Factory method
roles can be divided into general inheritance relationships and restricted inheritance relationships. Generally, the inheritance relationship only requires that the role inheritance relationship is an absolute partial-order relationship, allowing multi-inheritance between roles. The restricted inheritance relationship further requires that the role inheritance relationship is a tree structure. C . The responsibility separation relationship is added to the rbac2
: after loading the persistence model, there is no V1 variable node in the calculation diagram.At the same time, you use the v1=tf.get_variable (name= "v1", Shape=[1]) method to generate a new variable node v1_1 in the current code's calculation diagram, not the variable node V1 in the loaded persistence model. In this case, the function function is invalidated . That is, you want to invoke the Get_variable
, in the specified time. If your database is read-only, the time between checkpoints can be very long. However, in a system that is frequently updated on the business, checkpoints occur nearly every minute. Click Https://msdn.microsoft.com/zh-cn/library/ms189573.aspx to see the detailed description. As discussed in the previous article, in the full recovery model, the transaction log maintains "inactive his

In the process of learning and development of model framework learning is particularly important, especially GIS two times development is closely integrated with the principle of GIS, the following describes the Mapgis data management and display model.(This model is relatively simple, suitable for beginners to learn t
The measurable performance management model needs to build the underlying data at the very beginning, and the underlying data must come from the real, i.e. we must do the following:1, through some methods to the real data collection up;2, the application of these methods can not affect the normal progress of the project;3, these methods can effectively collect data, but not become the source of false data.T

The previous two sections describe the distribution process for Android click events. In fact, we can carefully understand that this distribution process is always from the top floor to the lower level. One layer at a level in order.Of course, to which layer to stop, we can do it by rewriting some methods.This is where Android developers are using the responsibility chain model to do this code. Let's take a
