Some of the very large relational systems using NCR Teradata technology extend into the hundreds of terabytes. These systems provide relatively efficient systems for storage and retrieval of account-centric information. Account-centric systems were quite efficient for their intended purpose, but they have a major drawback: it is difficult to manage customers per se as the primary responders, rather than accounts.
One person could have one account or multiple accounts. One account could be owned by more than one person.
As a result, it was very difficult for a company on an RDBMS to relate its business to specific customers. Also, accounts per se don't download products or services; products don't download themselves. People download products and services, and our businesses operations and the databases that serve them should be oriented around the customer, not around accounts. When we store data in a customer-centric format, extracts to build the Customer Analytical Record CAR are much easier to create.
And customer-centric databases are much easier to update in relation to the customer. The Physical Data Mart One solution to this problem is to organize data structures to hold specific aspects dimensions of customer information. These structures can be represented by tables with common keys to link them together. This approach was championed by Oracle to hold customer- related information apart from the transactional data associated with them.
The basic architecture was organized around a central fact table, which stored general information about a customer. This fact table formed the hub of a structure like a wheel Figure 2. This structure became known as the star-schema. Another name for a star-schema is a multidimensional database. In an online store, the dimensions can hold data elements for Products, Orders, Back-orders, etc. The transactional data are often stored in another very different data structure.
The customer database system is refreshed daily with summaries and aggregations from the transactional system. This smaller database is "dependent" on the larger database to create the summary and aggregated data stored in it. When the larger database is a data warehouse, the smaller dependent database is referred to as a dependent data mart. In Chapter 3, we will see how a system of dependent data marts can be organized around a relational data warehouse to form the Corporate Information Factory.
The Virtual Data Mart As computing power and disk storage capacity increased, it became obvious in the early s that a business could appeal to customers directly by using characteristics and historical account information, and Customer Relationship Management CRM was born. One-to-one marketing appeals could be supported, and businesses became "smarter" in their ability to convince customers to download more goods and services.
This success of CRMoperations changed the way some companies looked at their data. No longer must companies view their databases in terms of just accounts and products, but rather they could view their customers directly, in terms of all accounts, products and demographic data associated with each customer. Householded Databases Another way to gain customer-related insights is to associate all accounts to the customers who own them and to associate all individual members of the same household.
This process is called householding. The householding process requires some fuzzy matching to aggregate all accounts to the same customer. The reason is that the customer names may not be spelled exactly the same way in all records. An analogous situation occurs when trying to gather all individuals into the same household, because not all addresses are listed in exactly the same format.
The householded data structure could consist of the following tables: Accounts Individuals Households Historical data could be combined with each of the preceding hierarchical levels of aggregation. Alternatively, the preceding tables could be restricted to current data, and historical data could be installed in historical versions of the same tables e.
This compound structure would optimize speed of database queries and simplify data extraction for most applications requiring only current data. Also, the historical data would be available for trending in the historical tables. The data paradigm shift The organization of data structures suitable for data mining requires a basic shift in thinking about data in business.
Data do not serve the account; data should be organized to serve the customer who downloads goods and services. To directly serve customers, data must be organized in a customer-centric data structure to permit the following: Relationship of all data elements must be relevant to the customer.
Data structures must make it relatively easy to convert all required data elements into a form suitable for data mining: the Customer Analytical Record CAR. This process is similar to preparing for a vacation by automobile. If your camping equipment is stored in one place in your basement, you can easily access it and load it into the automobile. If it is spread throughout your house and mixed in with noncamping equipment, access will be more difficult because you have to separate extract it from among other items.
Gathering data for data mining is a lot like that. If your source data is a data warehouse, this process will denormalize your data. Denormalization is the process of extracting, data from normalized tables in the relational model of a data warehouse. Data from these tables must be associated with the proper individuals or households along the way. See any one of a number of good books on relational data warehousing to understand what this process entails.
If your data are already in a dimensional or householding data structure, you are already halfway there. The CAR includes the following: All data elements are organized into one record per customer. One or more "target" Y variables are assigned or derived. These data constructs are analyzed by either statistical or machine learning "algorithms, " following specific methodological operations.
Algorithms are mathematical expressions that describe relationships between the variable predicted Y or the customer response and the predictor variables [X.
The data mining aspect of KDD consists of an ordered series of activities aimed at training and evaluating the best patterns for machine learning or equations for parametric statistical procedures. These optimum patterns or equations are called models.
Major activities of data mining Major data mining activities include the following general operations Hand et al. Descriptive Modeling: This activity forms higher-level "views" of a data set, which can include the following: Determination of overall probability distributions of the data sometimes called density estimations ; Models describing the relationship between variables sometimes called dependency modeling ; Partitioning of the data into groups, either by cluster analysis or segmentation.
Cluster analysis is a little different, as the clustering algorithms try to find "natural groups" either with many "clusters, " or in one type of cluster analysis, the user can specify that all the cases "must be" put into x number of clusters say, for example, three cluster groups.
For segmentation, the goal is to find homogeneous groups related to the variable to be modeled e. Predictive Modeling: Classification and Regression: The goal here is to build a model where the value of one variable can be predicted from the values of other variables.
Classification is used for "categorical" variables e. Regression is used for "continuous" variables e. Discovering Patterns and Rules: This activity can involve anything from finding the combinations of items that occur frequently together in transaction databases e. Analyses like these can be used to generate association rules; e.
Development of association rules is supported by algorithms in many commercial data mining software products.
SALanalysis develops not only the associations, but also the sequences of the associated items. From these sequenced associations, "links" can be calculated, resulting in Web link graphs or rule graphs see the NTSB Text Mining Tutorial, included with this book, for nice illustrations of both rule graphs and SAL graphs.
Retrieval by Content: This activity type begins with a known pattern of interest and follows the goal to find similar patterns in the new data set. This approach to pattern recognition is most often used with text material e.
To those unfamiliar with these data mining activities, their operations might appear magical or invoke images of the wizard. Contrary to the image of data miners as magicians, their activities are very simple in principle. They perform their activities following a very crude analog to the way the human brain learns. Machine learning algorithms learn case by case, just the way we do.
Data input to our senses are stored in our brains not in the form of individual inputs, but in the form of patterns. These patterns are composed of a set of neural signal strengths our brains have associated with known inputs in the past. In addition to their abilities to build and store patterns, our brains are very sophisticated pattern recognition engines.
We may spend a lifetime building a conceptual pattern of "the good life" event by event and pleasure by pleasure. When we compare our lives with those in other countries, we unconsciously compare what we know about their lives data inputs with the patterns of our good lives. Analogously, a machine learning algorithm builds the pattern it "senses" in a data set.
The pattern is saved in terms of mathematical weights, constants, or groupings.
