It is passing on, to others, the important matters revealed by the data
the data are presented in paragraph form

Direct access means going straight to the record you want,and random access means pick data randomly and then find that data which you required.http://wiki.answers.com/Difference_between_direct_and_sequential_access#ixzz1685bfqda

What is data presentation on research
The presentation layer is responsible for how data is displayed to the user. It formats the data for presentation, including aspects like layout, colors, fonts, and responsiveness to user input. It focuses on ensuring that the data is presented in a meaningful and user-friendly way.
There are essentially four main components: Operational Source Systems, Data Staging Area, Data Presentation Area, and Data Access Tools. Although Operational Source Systems is part of the model, Kimball states "The source systems should really be thought of as outside the warehouse"Operational Source SystemsOperational Source Systems are those databases that hold all the transactional data. There is nearly no interaction with the Data Presentation Area and the Data Access Tools. The main priorities are processing, performance, and availability.Data Staging AreaThe Data Staging Area is temporary location where data from source systems is copied. A staging area is mainly required in a Data Warehousing Architecture for timing reasons. In short, all required data must be available before data can be integrated into the Data Warehouse.Due to varying business cycles, data processing cycles, hardware and network resource limitations and geographical factors, it is not feasible to extract all the data from all Operational databases at exactly the same time. (Source: data-warehouses.net)Data Presentation AreaThe data presentation area is considered to be a set of integrated data marts. A data mart is a subset of the data warehouse and represents select data regarding a specific business function (Inmon, 1999). An organization can have multiple data marts, each one relevant to the department for which it was designed. For example, the English department may have a data mart reflecting historical student data including demographics, placement scores, academic performance, and class schedules. The data contained in the data presentation area must be detailed and logically organized.Data Access ToolsData Access Tools are really all the software that can query the data in the data warehouse's presentation area. Data Access Tools are those like Cognos 10, SAP BeX, MicroStrategy, and Roambi. A data access tool can be as simple as an ad hoc query tool or as complex as a sophisticated data mining or modeling application.
Excel uses charts as the best way for visual presentation of data. Even data laid out well in tables could be said to be visually presented, but charts are the proper answer.
The data is held by RAM(random access memory) or primary memory when it's being processed.
Data can be imported from other applications and displayed in Powerpoint. Data can be presented in tables that could have come from other applications, such as Excel, Access or Word. Links can enable the data in the presentation to always be up to date, so when the other files change, the presentation will have the most up to date data. Powerpoint can show the actual data in the files, or just have links to the files on the slides that the user can clidk on to open the files.
one of the major disadvantages of tabular presentation of data is that it does not give a detailed view of the diagram, unlike textual(descriptive) presentation
