master data management applications

Currently, Oracle is the largest database, and its management system is also the fastest growing. How can we better utilize the powerful data management functions of Oracle databases in practical applications? This has become an important issue in Oracle system optimization. This article attempts to explore its "potent

Introduction to Application Background In many typical industry applications, data that is generated and maintained according to geography, time, or category dimensions is needed. The managed data classification is maintained in a constant manner, while the content (field) of the data itself needs to evolve according

The default settings of the system are usually for Small and Medium-sized applications and cannot meet the requirements of large databases.

Therefore, the administrator needs to configure relevant rules based on the actual situation. Specifically, the following parameters are involved. 1. The DB_CREATE_FILE_DEST parameter. As the name suggests, this parameter is mainly used to specify the default storage location of

understood as ring3 and ring 0.Commands that can be called only in some core states are not permitted due to low user-state permissions. These are two memory protection modes. Each page in a 4G address space of a process is marked as whether it is in the core State, and all pages in the system address space are in the core state, the page in the user space is in the user State.The only way to access the page marked as the core is to run in the core State, and only the operating system and the d

In general

. Because inventory management operations occur in the warehouse, before performing relevant operations on the materials, you must create records of the materials in the warehouse, you need to create material data in the material-warehouse file. Material-the supplier document is to associate a certain material with its supplier.Only after the records of the main material file are created can the correspondi

In Oracle 9i, data can be easily exported to a file or imported from a file. With Oracle's Management Server (Oracle Management server,oms) can be easily implemented, there are many places to explain the entire operation, but the complete guidance is not much. Many of the major forums on the so-called master, the answe

In the previous articleArticleIn the scenario design and requirements list in the data solution R D diary of the knowledge management system, many requirements are mentioned. This article describes the software required to complete these functions. TheseProgramHave been written, completed in C #. NET and SQL Server 2005. Let's take a look at the software data

Users can manipulate objects directly in the document without switching to different windows, improving the operating environment. Instead of focusing on the application and

Although C # (in fact all languages Based on. Net Framework) automatically handles the issue of memory allocation and release, and introduces the garbage collection mechanism, which provides comprehensive data type management capabilities. However, in many cases, it is very useful to understand its deep mechanism, which can greatly improve the program efficiency. Now, Phone7 is released on mobile devices an

The same project can sometimes involve multiple databases, or multiple data sources. Multiple data sources can be divided into two situations:1) Two or more databases are not relevant, independent of each other, in fact, this can be developed as two projects. For example, in the game development of a database is a platform database, and other platforms under the game corresponding database;2) Two or more da

, if the node failure in the query process, then the whole query to start from scratch. This strategy of restarting tasks makes it difficult for parallel databases to handle lengthy queries on clusters that have thousands of nodes, because node failures often occur in such clusters. Based on this analysis, the parallel database is only suitable for applications with relatively fixed resource requirements. However, many design principles of parallel da

At present, the telecom, finance, retail and other industries want to use big data analysis means to help themselves make rational decisions. In particular, the telecommunications and financial industry performance is particularly prominent, market data can not be connected with user consumption data. The first problem they face is the problem of massive

SummaryThe main components and applications of Laxcus are expounded from several angles. All designs are based on real-world assessment, comparison, testing and consideration. The basic idea of the design is very clear, that is, the functions of decomposition, refinement, classification, the formation of one can be independent, small modules, each module to undertake a function, and then organize these modules, in a loose coupling framework

relationship between Java applications and persistent data management has long been difficult to deal with. Many persistence mechanisms store data in relational methods rather than object-oriented methods. That is, the data is stored in a table that consists of records that
