Java® programming uses Java® data objects (JDO) to transform data from a database into the Java® programming language. JDO is a standard method for accessing and modifying data, using object-relational mapping. While JDO has benefits, it may not be suitable for complex data manipulation. Java® programming is a computer software language that uses forms and […]
Lookup data structures allow for automatic searching of large databases or lists. There are two types: static and dynamic. Searching can be expensive, so structures are optimized. Any data structure can be a lookup structure, but it must have at least two elements. The benefit is quick searching, but it’s not as useful for small […]
Dynamic data refers to electronic information that changes as needed or desired. Websites use dynamic data to display content on the fly based on changing conditions, such as inventory levels or personal preferences. Web developers use script coding programming languages and databases to create dynamic data. Time and date can also be displayed dynamically on […]
The Data Protection Directive is a law passed by the EU in 1995 to protect privacy and identifying information during data collection, handling, and processing. It standardizes data protection procedures, covers various types of data, and limits unauthorized disclosure of information to countries outside the EU. Companies must have safeguards in place to protect data. […]
Dynamic Data Exchange (DDE) is a Microsoft protocol for exchanging data between Windows applications. It establishes communication channels between client and server applications, and can be executed once or dynamically updated. DDE has been superseded by OLE and COM, but is still used for certain purposes. Dynamic Date Exchange (DDE) is a Microsoft® message-based computer […]
Online data migration involves transferring large volumes of data from one location to another, often for reasons such as changing hosting services or upgrading software. This can include website migration or moving sensitive data for businesses or banks. Specialized companies offer services to assess needs and transfer data securely. Online data migration refers to the […]
Data storage technology (DST) is a magnetic tape medium used for archiving or erasing computer memory. It comes in a cassette and is popular with businesses due to its large storage capacity, despite being slow. DST cassettes are more durable than reels and can hold hundreds of gigabytes. They are specialized for TV broadcasters but […]
Data warehouse models are used to build physical applications of computer system data models. There are several types, including Flat, Hierarchical, Relational, and Dimensional. Relational and Dimensional models are the most common, with other types being minor improvements to the basic methods of organizing. A data warehouse model is an applied form of a computer […]
Arrays store similar data in a linear sequence, allowing fast access to any part. They are static and have predictable memory addresses, making them ideal for sorting and hash tables. An array data structure is a method of storing similar types of data in a linear sequence. This linear sequence allows very fast and efficient […]
Interactive data visualization tools allow organizations and individuals to analyze real-time user data and emerging global trends through graphical representations such as charts, maps, and indicators. These tools provide instant graphical responses to real-time changes and help distill complex information into clear, actionable data. Other varieties include mind maps and heatmaps. Building an online presence […]
Offsite data protection involves storing data in a different location to minimize the risk of loss due to natural disasters or hardware failure. It can also be used for sensitive data or in insecure environments. Remote backup services are common, but physical media may be more secure. Storage facilities are usually secure, but it’s important […]
Data mining algorithms are programs used to find patterns in data sets, primarily to determine customer needs. Clustering and closest neighbor predictors are examples. The algorithms require decision-making and can identify patterns within large data volumes. Developers in business intelligence or data mining create algorithms to predict future actions, providing valuable information to organizations. Data […]
Big data is too large for ordinary databases and requires special machines. It comes in three sizes: small, medium, and large. Big data starts around the terabyte level and causes problems when attempted on non-specialized databases. Defense, military, and scientific agencies use big data for modeling and archiving. Big data is measurement of data that […]
Data masking is used to protect information in data management systems by preventing corruption and limiting access to relevant information. It involves encrypting data for testing and development purposes while masking sensitive data. Consistency in masking protocols is important, and any type of data can be protected. The process must be difficult to break for […]
Data deduplication eliminates duplicate data, reducing storage space and expenses. It can work in file-level or block-level ways, periodically reviewing data for duplicates. These systems are part of a larger system for data compression and management, and require proper antivirus protection and backup. They can run faster and more efficiently, especially on email servers with […]
A data warehouse is a specialized database for analytical reporting. The approach to building one depends on the organization’s reporting needs. Data is broken down into groups for simplified reporting, and a data warehouse implementation separates a company’s information. Examples include people-based, financial, and sales-based data warehouses. Fact tables and dimension tables are joined using […]
Data mining companies help clients analyze data for sales, marketing, and customer evaluation. They evaluate client data and use various types of data to create an information profile. They work confidentially and specialize in specific industries. Data mining can uncover obscure information that is valuable for specific situations. Data mining companies are companies that help […]
A data warehouse appliance is a hardware and software solution designed for high data throughput and analytics. It includes servers, storage, DBMS, and pre-installed software optimized for data warehousing. It streamlines data processing, supplants conventional BI functions, and can perform 10 to 100 times faster than generic systems. It has a significant positive impact on […]
Online data visualization simplifies internet information into network graphics. It focuses on online data and is web-based. Programs are segmented for specific niches, such as social media or finding similar items. Graphics make information easier to understand and differentiate. Online data visualization takes the complex web of information available on the internet and simplifies it. […]
Data visualization software allows for easy representation of data through pictures and graphs. Choosing the right program depends on your needs, with drag-and-drop interfaces being easier to use but limiting, while programming interfaces offer more freedom. Web export features are useful for sharing visualizations online. Specialized programs may be necessary for specific types of visualizations. […]
