Definition: Operational Data Store (ODS) An Operational Data Store (ODS) is a database designed to integrate data from multiple sources for additional operations such as reporting, analysis, and auditing, while ensuring that operational systems are not disrupted by these activities. An ODS provides a centralized, integrated, and up-to-date view of

Definition: Lambda Architecture Lambda Architecture is a data-processing architecture designed to handle massive quantities of data by providing a robust method to ingest, process, and analyze data with both a batch and a real-time processing method. This architecture is particularly beneficial in scenarios where both large-scale and real-time analysis need

Definition: Routing Table A routing table is a set of rules, often viewed as a table, stored in a router or a networked computer, that lists the routes to particular network destinations. The routing table contains information about the topology of the network immediately around it. The primary function of

Definition: Log-Structured Merge-tree (LSM-tree) A Log-Structured Merge-tree (LSM-tree) is a data structure primarily used for writing and reading data in write-intensive applications. It is designed to optimize systems that require high write throughput, such as large-scale database management systems and NoSQL databases. The LSM-tree achieves its efficiency by first writing

Definition: Data Index A data index is a data structure that improves the speed of data retrieval operations on a database table at the cost of additional writes and storage space to maintain the index data structure. Indexes are used to quickly locate data without having to search every row

Definition: Hash Map A hash map is a data structure that stores key-value pairs. It uses a hash function to compute an index into an array of buckets or slots, from which the desired value can be found efficiently. Similar to hash tables, hash maps are designed to optimize the

Definition: Hash Table A hash table is a data structure that implements an associative array abstract data type, a structure that can map keys to values. Hash tables use a hash function to compute an index into an array of buckets or slots, from which the desired value can be

Definition: Job Queue A job queue is a data structure used for job scheduling in computing, where jobs, tasks, or processes are kept in order while they await execution. Job queues help manage and optimize the order and time that processes are executed by a scheduler, typically within an operating

Definition: Inode An inode (index node) is a data structure in Unix-like file systems that stores information about a file or a directory. This information includes metadata about the file, such as its size, owner, permissions, and disk location. Every file or directory is uniquely identified by an inode, and

Definition: License Key A license key, also known as a product key, is a specific software-based key for a computer program. It certifies that the copy of the program is original and has been legally acquired. This alphanumeric code is used to activate and operate the software, ensuring that it

Definition: RAID (Redundant Array of Independent Disks) RAID stands for Redundant Array of Independent Disks. It is a data storage virtualization technology that combines multiple physical disk drive components into a single logical unit for the purposes of data redundancy, performance improvement, or both. Understanding RAID (Redundant Array of Independent

Definition: Virtual Tape Library (VTL) A Virtual Tape Library (VTL) is a data storage solution that emulates physical tape storage, but uses hard disk or other high-speed storage media to store data. It is designed to integrate seamlessly with existing tape backup processes, providing a bridge between older tape-based backup
