What are the strategies for the development of management information systems_What are the two strategies for the development of management information systems_Baidu...

1. Entrusted development: You need strong planning ability to be able to write your own needs clearly and completely, which is actually very difficult. People often see something and go through trial It's clear. Therefore, this method is easy to pull the skin in the later stage.

2. "top-down" development strategy "top-down" development strategy is in line with the system's point of view.Adopt this strategy to consider the problem as a whole. First, systematically analyze the enterprise or organization, from long-term to near-term, from comprehensive to partial, to find a more reasonable logistics and information flow for enterprises or organizations.

3. Even from a new plan and design. From top to bottom" MIS development strategy: Advantages: This development strategy has a strong logic, coordination and planning from the whole, from comprehensive to partial, from long-term to near-term, from exploring reasonable information flow to design information systems. Disadvantages: It is difficult to implement.

4. Two strategies for developing management information systems: bottom-up strategy, starting from the current system, first realize specific functions, gradually establish MIS from low-level to high-level, start from the development of various data processing applications, and then gradually increase relevant management according to needs. Functions of rational control.

security policy of database system

From the perspective of software engineering, it is not enough to protect data through access control and data encryption. Therefore, as an important supplementary means, the audit method is an indispensable part of the secure database system and the last important security line of defense of the database system.

The strategies to solve the secure storage of data include data encryption, user security authentication, data backup, the use of tracking filters, and data recovery.

The security of the database simply refers to ensuring the normal operation of the database and not being illegally used, stolen, modified and destroyed by unauthorized users. In real operation, network administrators generally ignore the security settings on the server side and leave the problem to the program developer to deal with.

The main measures to ensure the consistency and integrity of data and transactions are logging and data replication.

What is the strategy of system testing?

System test strategy: Test strategy is used to describe the general methods and goals of a specific test work.

Unit testing refers to the inspection and verification of the smallest testable unit in the software. The pile module (stud) refers to the module called by the simulated module under test, and the driver refers to the superior module of the simulated module under test. The drive module is used to receive test data, start the tested module and output the results.

Strategy is part of the plan to guide the testing work.Use cases are the basis for performing actual testing. For example: a login interface.

The test plan can help testers clear their thinking, improve test efficiency, and let others understand the progress and plan of the test. Perform tests: test according to the test plan and test cases, record the test results, and find and report problems in time.

Stress test: Perform repeatable load tests in a way that requires abnormal quantities, frequencies or resources to check the ability of the program to resist abnormal situations and find out performance bottlenecks.
