1. Application background1.1 Resolved issues1) IT systems for large enterprises will be tested in their test environment beforehand for each application upgrade. How to ensure the validity of the test? How can the results of the test be inferred from the performance of the production environment?2) as resource usage grows, resources such as CPU, memory, hard disk, I/O, and so on interact with each other and have potential associations. How do you gain insight into its relevance to guide your bus

our familiar domain, it is often found that in another adjacent field, there are many problems, ideas, ideas and knowledge are interlinked, as if the initiative opened a door, to explore the new "adjacent possible" provided the conditions. In fact, there are a lot of small creative ideas in this book that I was inspired to read in the non-test theory books. For example, the 5 main chapters of this book "Kym" "TCO" [8] "Modeling (

One of the basic reasons why modeling is:modeling is to better understand the systems under development2. By modeling, there are four objectives:(1) Modeling helps visualize the system according to the actual situ

Domain-driven design methods start with modeling. They mainly include information modeling, behavior modeling, and UI modeling; Information modeling is the beginning of a domain-driven design. Information Modeling partitions info

Object-Oriented Analysis and Design have suddenly emerged, software Enterprises are transitioning from process-oriented to object-oriented. On the other hand, rose embodies the advanced design ideas of Unified Software Modeling (UML), and can express various design ideas in a concise and effective manner through a unified set of graphical symbols. Of course, the commonly used UML modeling tool Rose is well

Comparison Between Rational Rose and powerdesigner modeling tools I,Their originsAs the world's two most famous case tools, rationalRose and powerdesigner are well known. Rose was the fist product of rational, the world's largest CASE tool provider at that time. The UML modeling language isInvented by three giants of rational, booch, Rumbaugh, and Jacob bson. Later, rational was acquired by IBM, So RoseHe w

people. For example: a part of a process requires the financial controller for approval, the future financial controller substitution, the process should not be affected. Also, a link in the process may be approved by any one of the departments, or all of the department's personnel will be required to approve it. 2 in the process of transfer, approval of documents generally divided into documents and forms 2 kinds of formats. File format documents should support batch processing, that is, you c

IBM SPSS Modeler and database integration and configuration IBM SPSS Modeler is a set of data mining tools that, as an important part of the IBM Analysis and prediction solution, can use commercial technology to quickly build predictive models and apply them to business activities to improve the decision-making process. It can process and model enterprise-class massive data, through powerful database integration function, can directly with the enterprise existing database integration data minin

The following is my personal experience with the "SQL Server Analysis Services Tabular Model Table Modeling" tutorial available on MSDN, which contains a picture instance of each lesson, step-by-Step document import from a data source, creating a relationship , computed columns, metrics, hierarchies, perspectives, roles to deployment, and so on each stage, is believed to be a useful supplement to this tutorial. If you feel light on MSDN on the text t

Starting from this article, the author will use a virtual example to illustrate the method of acquiring use cases, and how to determine whether the use case acquisition is complete, the granularity of choice is appropriate. In fact, in doing these things, we are doing the first phase of requirement analysis, the business modeling phase. With this example, I will also explain what business modeling should be

Enterprise Architect (EA) is an OMG UML-based visual model and design tool that provides support for the design and construction of software systems, business process modeling, and domain-based modeling, and is not only used by enterprises and organizations to model systems, It is also used for propulsion models to be implemented throughout the application development cycle.On the EA tool

Currently, two common methods of project architecture are transaction scripts and Domain Modeling. Transaction scripts have no architecture. They only use the natural architecture provided by the existing mature technology platform, or such as. NET and J2EE, to provide the transaction scripts and their implementation environments. The transaction script directly develops SQL and GUI, and directly operates the database through SQL In
