The process integrates analytical and […]
Statistical data mining is a computer-based method of gathering and analyzing information to discover patterns or correlations. It has five main steps and integrates analytical and transactional data systems. It collects three general types of data and has widespread practical applications, such as in medicine and computer programming. Google’s search engine was designed using statistical […]
Source data is information used to create electronic data, which can be scanned or manually entered. Scanning preserves valuable paper records and creates electronic images, while some scanners can process information and deposit it in a database. Source data can also be manually entered into a database, allowing for editing and sharing without damaging the […]
Data warehousing tools are divided into four categories: data extraction, table management, query management, and data integrity. Personnel require specific skills in statistics, advanced mathematics, processing logic, relational databases, and computer skills. An extract, transform, and load (ETL) tool is used to add data to the warehouse. Maintaining tables and ensuring data integrity is crucial. […]
Data warehousing tools are divided into four categories: data extraction, table management, query management, and data integrity. Specific skills are required for personnel working with data warehousing tools. A data warehouse requires an ETL tool for adding data and maintaining database tables is essential. Business intelligence specialists create and manage custom queries while data integrity […]
Data Manipulation Language (DML) is a computer language used in databases to manipulate data. DML commands include adding, modifying, deleting, and moving data. It can be split into procedural and non-procedural code. Without DML, manipulating data in the database would not be possible. Data Manipulation Language (DML) is a structured computer language used in databases […]
CRM data mining analyzes customer behavior to improve marketing campaigns and increase sales. Descriptive analytics uses segmentation and clustering to group customers by characteristics, while predictive modeling measures correlation between factors to predict future behavior. Specificity is important, and different methods are used, including univariate, CHAID, CART, and multivariate regression models. CRM (Customer Relationship Management) […]
Data warehousing combines data from multiple sources into a comprehensive database for analysis and strategic planning. Access methods include queries, reports, and analytics. Smaller companies may use more limited formats like “data marts”. Data warehousing is not always the best method for storing all data. Data warehousing combines data from multiple, usually diverse, sources into […]
Data segments are self-contained sections that store information on a hard drive or database. Software applications reference these segments for execution and operation. Short-term memory is stored in RAM, while long-term memory is stored on a disk. Data segments are organized logically and sequentially. Software installers create log files for permanent code statements. A data […]
Data mining uses computing power and algorithms to find patterns and connections in large databases. It is used in corporate trends, decision support systems, and anti-terrorism efforts. Techniques include regression, Bayesian inference, and decision trees. Data visualization is important for presenting findings. As data becomes more abundant, data mining will become increasingly important. Data mining […]
Mass data storage is important for storing large amounts of information. Types include hard drives, optical discs, USB drives, and SD cards, each with advantages and disadvantages. Mass storage is not the same as computer memory and capacities range from kilobytes to terabytes. As the use of technology continues to grow at a rapid pace, […]
Persistent data is rarely changed and can be stored on a server or disk for archival purposes. It is useful for researchers and to reduce digital clutter on hard drives. Computers and storage devices are full of data, and there are many different forms of data, depending on how often the data is accessed or […]
Real-time data warehousing is the process of storing and analyzing data immediately as it becomes available to predict changes in customer demand and develop new marketing strategies. It allows for automatic generation of customized reports and on-demand reporting, providing information at your fingertips to make decisions that increase profits. Many companies are integrating real-time software […]
Data governance is the formal process of managing customer, product, and sales data within databases or spreadsheets. A data governance council manages access to a company’s data, ensuring it is only available to those who need it. Large companies struggle to build a data governance system, but a board of directors can be established by […]
Forensic data recovery is used to recover data for legal purposes by qualified technicians. It involves accessing areas of a computer to verify specific activities of interest and recovering intentionally deleted, damaged, or corrupted data. Specialists are interested in information and use various techniques to make it meaningful. They must also use special procedures to […]
Spatial data mining finds patterns in geographic data, commonly used in retail to make decisions about store locations. It is more challenging due to analyzing objects in space and time. It can also address the problem of false positives, but trends should be confirmed through further research. Spatial data mining is the process of trying […]
A data buffer is temporary storage for data being moved from memory to satisfy a query. It processes requests in a logical sequence and performs writing and reading tasks simultaneously. Buffers are used in telecommunications, corporate networks, and simple tasks like retrieving documents to prevent data corruption during transfer. A data buffer is a section […]
Data corruption can occur due to hardware, software, or user errors. Symptoms include slow computer performance and difficulty opening or deleting files. Hard drive failure, improper shutdowns, and operating system crashes can also cause data corruption. Malware and viruses can intentionally corrupt data. Data corruption is the term used to describe any type of error […]
Effective data management involves ownership, security, retention, and enhancement policies. A change control committee oversees system changes and data security policies vary based on the type of data. Government institutions have strict data handling procedures, and data privacy protection is important. Retention policies vary by company and department, and data access controls should include procedures […]
