Having aggregates and atomic data increases the complexity of the dimensional model. This complexity should be transparent to the users of the data warehouse, thus when a request is made, the data warehouse should return data from the table with the correct grain.
A data warehouse environment must ensure that data collected and stored in one big repository are not vulnerable. A review of security approaches specifically for data warehouse environment and issues concerning each type of security approach have been provided in this paper.

Data Preprocessing Techniques for Data Mining Winter School on Data Mining Techniques and Tools for Knowledge Discovery in Agricultural Datasets " 143 1. Normalization, where the attribute data are scaled so as to fall within a small specified range, such as1.0 to 1.0, or 0 to 1.0.
This is because data warehousing has become an overloaded term that includes BI tools (OLAP/data mining), data extraction and transformation tools (ETL), and schema management tools.
The definition of data analytics, at least in relation to data mining, is murky at best. A quick web search reveals thousands of opinions, each with substantive differences. On one hand, data analytics could include the entire lifecycle of data, from aggregation to result, of which data mining is a small part.

Data Warehouse and OLAP Data Warehouse and DBMS. What is Data Warehouse? A decision support database that is maintained separately from the organization's operational database. Support information processing by providing a solid platform of consolidated, historical data for analysis.
A data warehouse is in most systems indeed like a relational database. The biggest difference is that traditional databases tend to keep only operational records in a normalized table structure
Data warehouse metadata are pieces of information stored in one or more special-purpose metadata repositories that include (a) information on the contents of the data warehouse, their location and their structure, (b) information on the processes that take place in the data

Data mining deals with the discovery of hidden knowledge, unexpected patterns and new rules from large databases. It is regarded as the key element of a much more elaborate process called knowledge discovery in databases, or KDD, which is closely linked to data warehousing.
Data mining is the analysis of data and the use of software techniques for finding patterns and regularities in sets of data. The computer is responsible for finding the patterns by identifying the underlying rules and features in the data.
