Data logging is the process of gathering information to understand a system or process. Loggers store information such as temperature using sensors and can be standalone or PC-based. Data logging is used in various situations, including weather systems and aircraft black boxes. It provides vital information for performance, quality, efficiency, and cost reduction. The equipment […]
Open source data visualization software allows individuals to analyze large datasets for free using different types of graphs and charts. More complex data requires advanced visualization software, such as network analysis. Open source software can save money, but may not have advanced features. Web services can create graphics, such as word clouds. Open source software […]
Graphical data visualization displays and organizes data using graphics, making it easier to understand and remember. It can be simple or complex and is used for local computer data or non-computer data. Visualizations focus on a narrow niche of information and use text to label graphics. It serves a useful purpose as it is more […]
Data warehousing is crucial for businesses, but performance can degrade over time due to increased data mining and usage. Improving infrastructure, deleting outdated data, and providing training can all improve data warehouse operations. As data warehousing has become increasingly important to businesses, increasing data warehouse performance has become vital. A company’s data warehouse contains information […]
A data definition language creates, deletes, and modifies data structures. It applies to all languages, but is commonly used in SQL and XML. It must provide three functions: constructing data structures, deleting them selectively, and altering them without losing information. A data definition language is a computer programming or scripting language that defines a data […]
SDLC is a protocol used in IBM’s SNA for data transmission through layer two. It was developed for WAN solutions for IBM mainframe computers and uses byte-based transmissions. SDLC frames contain flags, address, control bytes, data payload, and redundant sequence control. SNA environments using SDLC can support different topologies such as point-to-point, multipoint, loop configuration, […]
Data flow diagrams document how information enters and leaves an information system, with varying levels of detail. They help development teams manage data storage, track interactions between systems, and comply with government regulations. They also aid in designing reports and screen functionality. A data flow diagram is a structured visualization of data entering and leaving […]
Data warehouse software is a repository of transactional data used to analyze and run complex reports. It has three main functions: data extraction, database structure creation, and custom query creation. Data architects manage the loading process and identify shared data. Custom reporting is essential for specific business needs. Data warehouse software has grown exponentially in […]
Data mining software identifies patterns in large data sets, helping companies turn information into actionable insights. The process involves raw data conversion, mining programming script, and interpretation, and requires a solid understanding of data concepts. The software uses regression analysis, fuzzy logic, and algorithms to identify models based on user specifications, but poorly defined specifications […]
An operational data store catalogs dynamic data generated at random intervals from sources outside typical business methods. The data is confusing and poorly referenced, requiring heavy processing before long-term archiving. Most work involves cleaning it, moving it to correct fields, correcting spelling errors, filling in missing entries, and cross-referencing data with internal databases. An operational […]
Data classification is the analysis and categorization of an organization’s data assets to determine appropriate access, storage, and retention. It helps understand security, legal and compliance requirements, business importance, availability needs, and current location. It benefits an organization by meeting legal and compliance requirements, reducing backup and archiving costs, and providing more effective use of […]
Data visualization applications allow users to view information in different visual representations. To choose the best one, consider your purpose, preferred style, and read reviews. Also, check compatibility and consider free options. Data visualization applications are computer programs that allow users to view information in different visual representations. For example, a person interested in learning […]
Data encryption encodes plain text data into unrecognizable values for security. The Data Encryption Standard (DES) was the first standard for encrypting digital data, but was replaced by the Advanced Encryption Standard (AES) due to its small key size. Triple DES is a slower variation of DES that is still used today. Data encryption is […]
A data warehouse architect designs and oversees the construction of a system for storing and accessing large amounts of electronic data. They coordinate with others in the organization and must have knowledge of industry-specific data collection methods. They also monitor data accuracy, lead analysis and oversee training efforts. A data warehouse architect is responsible for […]
A data dictionary is a critical document for managing a computer database, providing a detailed map of each file item and table, including field names, types, and descriptions. It also defines format rules, constraints, and data integrity rules, making it necessary for legacy databases and non-intuitive designs. The dictionary helps future developers understand the system […]
RAID (Redundant Array of Inexpensive Disks) was originally designed to prevent data loss by writing to multiple hard drives. However, multiple drive failures can occur, and RAID users often have less strict backup schemes. RAID data recovery can fix logical and physical damage, but costs vary depending on the extent of damage. It’s best to […]
Data deletion is the act of removing information from a computer to free up space or for security reasons. It can improve performance and prevent unauthorized access. Operating systems offer some protection against accidental deletion, but data wiping software is needed for complete removal. Data deletion is the act of deleting information from a computer, […]
Data flow architecture is a form of reactive programming where each function is generated from the previous one, allowing for parallel data flow. It is compared to a factory assembly line and is simple to use but has limitations. It is opposed to von Neumann architecture, which cannot handle parallel processes. Data flow architecture is […]
Data stewardship involves creating, maintaining, and auditing databases. Professionals typically need a degree and certifications. It involves critical thinking, planning for growth, and data integrity. Data stewards control databases, plan upgrades, and determine access levels. A degree in computer science or related field is required, and certifications can be helpful. Junior roles lead to more […]
The Data Reference Model (DRM) is an XML-based system that standardizes data entered by US federal agencies, allowing for easy sharing and retrieval. It is part of the Federal Enterprise Architecture and includes a Community of Interest (COI) for sharing data with non-governmental bodies. The DRM promotes easy retrieval through standardized data descriptions, categorizations, and […]
