Databases are organized collections of data typically collected by schemas, tables, queries, reports and views. Databases are typically organized to process data to provide quick information retrieval. Objectives and skills for the databases portion of CLEP Information Systems include: Database management systems (data warehousing, data mining, networking, security, validation, migration, storage, obsolescence) Database management systems (relational, hierarchical, network, management strategies) Difference between multidimensional, object-oriented, hierarchical, and relational databases.

Review QCI: Database vs. Spreadsheet and PC Magazine: Spreadsheet Does Not = Database. Identify spreadsheets you use at work, school, or home that should be implemented as databases instead. If you are responsible for the data, try creating a database as a replacement. If someone else is responsible for the data, discuss with them the advantages of using a database. Identify different database management systems that you frequently use. Identify potential benefits and limitations of information stored in those systems. Research the various levels of security used to protect database management systems. A database is an organized collection of data, including schemas, tables, queries, reports, views and other objects. A database management system (DBMS) is a computer software application that interacts with the user, other applications, and the database itself to capture and analyze data. It allows you to keep accurate records and retrieve records quickly. A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases. Because of the close relationship between them, the term "database" is often used casually to refer to both a database and the DBMS used to manipulate it. A data warehouse is a central repository of integrated data from one or more disparate sources used for reporting and data analysis. Data mining is the computational process of discovering patterns in large data sets involving methods at the intersection of artificial intelligence, machine learning, statistics, and database systems. A relational database management system (RDBMS) is a database management system (DBMS) that is based on the relational model. The relational model represents data terms of ordered sets of elements (tuples), grouped into relations (tables). A hierarchical database model is a data model in which the data is organized into a tree-like structure. The data is stored as records which are connected to one another through links. A record is a collection of fields, with each field containing only one value. The entity type of a record defines which fields the record contains. An object database is a database management system in which information is represented in the form of objects as used in object-oriented programming. The network model is a database model conceived as a flexible way of representing objects and their relationships. Its distinguishing feature is that the schema, viewed as a graph in which object types are nodes and relationship types are arcs, is not restricted to being a hierarchy or lattice. Network databases create multiple linkages between sets by placing links, or pointers, to one set of records in another; the speed and versatility of network databases have led to their wide use within businesses and in e-commerce. Data migration is the process of transferring data between computer storage types or file formats. It occurs for a variety of reasons, including server or storage equipment replacements, maintenance or upgrades, application migration, website consolidation and data center relocation. Data warehouses (known as DW, DWH, and EDW) are systems used for reporting and data analysis. Current and historical data uploaded from the operational systems in stored in one single place and is used for creating analytical reports.. centralized database A database that is located, stored, and maintained in a single location. client / server A distributed application structure that partitions tasks or workloads between the providers of a resource or service and service requesters. data cleansing The process of detecting and correcting or removing corrupt or inaccurate records from a record set, table, or database. data mining The computational process of discovering patterns in large data sets involving methods at the intersection of artificial intelligence, machine learning, statistics, and database systems. data security protecting data, such as those in a database, from destructive forces and from the unwanted actions of unauthorized users. data validation The process of ensuring that a program operates on clean, correct and useful data. data warehouse A central repository of integrated data from one or more disparate sources used for reporting and data analysis. database administrator (DBA) The role responsible for installation, configuration, design, migration, capacity planning, performance monitoring, security, troubleshooting, as well as backup and recovery of a database or databases. database management system(DBMS) software for creating and managing databases[source?] database model Determines the logical structure of a database and fundamentally determines in which manner data can be stored, organized, and manipulated. database storage The container of the physical materialization of a database. It comprises the internal (physical) level in the database architecture. database schema The structure of a database described in a formal language supported by the database management system. digital obsolescence A situation where a digital resource is no longer readable because of its archaic format. distributed database A database in which portions of the database are stored on multiple computers within a network. export The act or process of retrieving data out of data sources for further data processing or data storage (data migration). field A column or attribute of a record in a relational database. geographical information system (GIS) A system designed to capture, store, manipulate, analyze, manage, and present all types of spatial or geographical data. hierarchical database A data model in which the data is organized into a tree-like structure. import The act or process of loading data into a data source. join (SQL) combines columns from one or more tables in a relational database. migration The process of transferring data between storage types, formats, or computer systems. multidimensional database A database which uses aggregated, inter-related arrays to organize data and express the relationships between data and is used for online analytical processing. network model A database model conceived as a flexible way of representing objects and their relationships. object oriented database A database management system in which information is represented in the form of combinations of variables, functions, and data structures. NoSQL (Originally referring to "non SQL" or "non relational") database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases. query A precise request for information retrieval with database and information systems. record A row or collection of attributes in a relational database. relation (database) A set of tuples (d1, d2, ..., dn), where each element dj is a member of Dj, a data domain. structured query language (SQL) A special-purpose programming language designed for managing data held in a relational database management system (RDBMS), or for stream processing in a relational data stream management system (RDSMS). table A collection of related data held in a structured format within a database. tuple A finite ordered list (sequence) of elements.
