systems have gone through more than 30 years. From the evolution of MRP/MRPII/ERP, we can analyze the evolution of manufacturing business informatization. The current business management information system ERP is evolving in three aspects: first, it is extended to the manufacturing process system to capture the changed data and processing quality information of the workshop in real time. The second is to extend to the product design system, and quickly convert the time from new products to prod

shouldTechnical and non-technical details are agreed upon during the evaluation. This plan needs to be further refined in the execution of other plans and preparation phase activities.Through the preparation of the evaluation team, an experienced,Trained and precisely positioned teams are ready to perform evaluation tasks. Members of the group should have the knowledge necessary to complete their respective tasks, or their previous knowledge is prove

manager of the Project tracks software costs, schedules, and functions, and identifies issues that arise during the performance of the commitment. Create software requirements and baseline for work products that meet these requirements, and control their integrity. After defining software project standards, the organization ensures that these standards are fully implemented. If a subcontractor exists, the software project can work with the subcontractor to establish a strong customer supplier r

the new feature (diasble) and transfer this risk; When some risks are inevitable, we try to reduce the risk. For example, the risk of "undiscovered defects in the Program" always exists. We need to improve the test case coverage rate (for example, 99.9%) to reduce this risk; In order to avoid, transfer or reduce risks, risk management plans and risk control strategies should be prepared in advance, and some emergency and effective solutions should

full table scan performance is better than the index, even if the same SQL statement, if the predicates are different, the execution plans may be different. The following principles apply to variables bound to an OLAP system: (1) There is no need to bind variables to the OLAP system, which will only bring negative effects. For example, the cost of incorrectly selecting SQL statements may sometimes be disastrous; oracle performs a hard Analysis on e

development environment is described in our main plan, and the test environment is described in the test plan. 10. various plans: Main plans (project resource plans, external stakeholder management plans, data plans, risk plans,

fields cannot be dependent on another 1 non-critical fields. The design that adheres to these rules produces fewer columns and more tables, thereby reducing data redundancy and reducing the number of pages used to store data. However, table relationships may need to be handled through complex mergers, which can degrade system performance. To some extent, the non-standard can improve the performance of the system, the non-standard process can be based on the performance of different considerati

. Business plans cannot be changed Traditional Business Plans and product models have a major advantage: they provide the founders with a clear development roadmap to guide them at what stage to achieve. There are also various financial indicators to constrain, such as profit and loss, negative assets and cash flow. But the problem is that none of these indicators are necessary because they cannot motivate

It is characterized by comprehensive management and synchronous use of all marketing-related information to achieve: Complete Marketing Use existing marketing information and knowledge to control the cycle of marketing plans, so as to maximize the ROI of marketing The functions of each function group in the marketing mana

how to organize testing. The plan should include the testing content, progress, conditions, personnel, selection principles of test cases, and allowable deviation range of test results. ◇ Test Analysis Report:After the test is completed, a description of the implementation of the test plan should be submitted, the test results should be analyzed, and the conclusions and opinions of the test should be put forward. ◇ Monthly Development Progress Report:This monthly report is the project progress

SQL Server execution plan cache (1) Overview Understanding the execution plan is very important for database performance analysis. It involves statement Performance Analysis and storage. This is also the purpose of writing this article. Before learning about the execution plan, you must first understand some basic knowledge, therefore, some concepts mentioned earlier in this article will be boring to learn, but these basic knowledge is very important. Basic Concepts SQL Server has a memory pool

One, what is the implementation plan (explain plans) Execution plan: A description of the execution process or access path of a query statement in Oracle. Ii. How to view the execution plan1: Under Pl/sql press F5 to view the execution plan. Third-party tools Toad and so on. Many people think that Pl/sql's implementation plan can only see the base, optimizer, consumption and other basic information, in fact, this can be set in the Pl/sql tool. Yo

. Therefore, it is not difficult to guess, as long as this kind of lookup, must not run hash (hash) of the data structure. By sys.dm_os_memory_cache_hash_tables This DMV can find some information about the hash table, as shown in Figure 2. It is worth noting that, when too many execution plans result in the hashing object being overloaded with the same bucket, additional bucket is required, which may cause the lookup plan cache to be inefficient. The

The following is a detailed analysis of several methods for obtaining execution plans in Oracle, which can be referred to under 1. Estimated implementation plan-Explain plansExplain Plan takes the SQL statement as input, gets the execution plans for the SQL statement, and stores the execution plan output in the schedule table.first, in front of the SQL statement you want to execute, add explain plan for, w

The SQL Server query optimizer is acost-based optimizer。 Itanalyze many candidate execution plans for a given query, estimate the cost per plan, and choose the plan with the lowest cost to consider。

Server does not have a Query Cache mechanism similar to MySql, but it has its own Cache mechanism. SQL Server does not directly cache the SQL query result set, but caches the queried Data pages (Data Buffer) It has read ), it also caches execution plans (process Cache Procedure Cache). Next we will talk about the well-known process Cache. 1. SQL Execution Process The SQL statement needs to be compiled before execution. Then, it needs to be optimized

I. Basic Concept: Oracle started at 11g and provided a new method for fixed execution plans, namely, SQL plan baseline, Chinese name SQL Execution plan baseline (baseline for short ), it can be considered as an improved version of OUTLINE or SQL profile. Basically, its main functions can be summarized as follows: 1. The execution plan of a given SQL statement is stable, prevent SQL statement execution plans
