, we can get an approximate direction of the OLTP. Although the overall data volume of the system is large, but the proportion of the system active data in the total data is small, we can enlarge the memory capacity to cache the active data in memory as much as possible; Although IO access is very frequent, but the amount of data accessed per visit is small and discrete, our requirement for disk storage is that IOPS perform well and throughput is a secondary factor; Concurrency is very high, CPU

Tags: ODI partial user process modification supports storage elementsWith Oracle 12c introducing the in memory component, the Oracle database has dual-mode data storage that enables support for mixed-type applications: traditional, row-saving data meets OLTP applications, and data stored in columns satisfies OLAP applications that are primarily queried. The in memory component can be used with other database component functions, and does not require t

The following content is taken from the Internet and sorted out. Terms: Bi (Business Intelligence): Business Intelligence, DW (data warehouse): Data Warehouse. For details, see section Q1. OLTP (on-line transaction processing): Online Transaction Processing It is also known as a transaction-oriented processing system. Its basic feature is that the customer's raw data can be immediately transmitted to the Computing Center for processing and the processing results can be given in a very short t

for management personnel. Data Warehouse is mainly used in decision support systems. Its main purpose is to "extract" Information and expand it to process the application of the data warehouse-based decision support system (DSS. 2 The Data warehouse-based decision support system (DSS) is composed of three components: Data warehousing and OLAP, on-Line Analytical Pro-cessing), Data Mining technology (Data Mining ).

Introduction to Mondrian MDX and mondrianmdx Introduction to Mondrian MDX MDX (multidimen1_expression) is the language used to construct and query OLAP databases, just as SQL is used to build and operate relational databases. MDX was the first developed by Microsoft and is part of the 1997 system ole db for OLAP (ODBO). Mosha Pasumansky is one of the MDX Language designers. MDX is soon implemented by oth

Roles Before discussing how the newly created role affects the xmla code of the oalkaline database, let's briefly describe the role in SSAs. The following is a role editing interface. Although it has seven option configuration interfaces (not discussed about the mining structure Interface), all of them can be classified into three categories: 1.Read defined Permissions A person with this permission can connect to the OLAP database, and then it wi

It provides an ETL platform in BW for ETL.It is worth mentioning that BW provides a standard bapi interface that allows third-party ETL tool providers to extract data from SAP data warehouses, resulting in many ETL third-party tools. No DW exists in the acquired Bo product l
