Clustering in the computer science world is the classification of data or object into different groups. It can also be referred to as partitioning of a data set into different subsets. Each data in the subset ideally shares some common traits. Data cluster are created to meet specific requirements that cannot created using any of the categorical levels....

In the realm of computer science a logical data model is the accurate representation of a company s data. These data need to be logically represented because later on they will be the basis for data modeling. Data modeling in turn will be the basis for database implementation as the computer needs to understand business entities and activities from...

In data modeling a logical data model is the representation of business data into a data model that can be the basis for the physical database implementation. It identifies a data periodic table" which will be the basis for the business organization s functions processes and task to be performed. Data modelers design a logical data model...

In the implementation of a structure query language SQL the term data cardinality is used to mean the uniqueness of the data values which are contained in a particular column known as attribute of a database table. There are actually three types of data cardinality each dealing with columnar value sets. These types are high-cardinality normal-cardinality...

Data characteristics are defined during data modeling a process where a data model is created by applying a data model theory in order to create a data model instance. A data model theory is a formal description of a data model. Data modeling is also a process of structuring data and organizing data so that the data structures will then be the basis...

In a logical data model the conceptual data model which is based on the business semantic is being defined. Thus entities and relationships and corresponding table and column design object oriented classes and XML tags among other things are being laid regardless of the database will be physically implemented. A data file is a physical file. This...

In some aspects of information technology a data element is referred to as any named unit of data which may or may not consist of other data items. In many electronic record keeping applications a data element is a combination of bytes or characters which refer to a separate item of information like name address and gender. A data element has a...

While implementing a Data Warehouse there are a multitude of complex things to consider. Data Management is one of the most important aspects that need to be considered aside from other things like physical server and network components. In Data Management the design of the Data Structure determines the smooth and successful implementation of the...

Cardinality is the term used in database relations to denote the occurrences of data on either side of the relation. In the common data architecture cardinality is documented with data integrity but not with data structure. There are several types of cardinality defining relationships between occurrences of entities on two sides of the line of relationships. The...

In big data warehouses such as those used by business organizations which may have many branches around the world and which may have diversified products and services different kinds of data flood the warehouse every single day. These data may come from other warehouse data sources or simply freshly entered from staff within various departments or...
