Data base 1.Banco of Data: Data set or information related between itself and organized of form to facilitate its use on the part of the user. It aims at: to 1.1.Diminuir the busy space for the information; to 1.2.Facilitar the update of the information; to 1.3.Aumentar the research speed; to 1.4.Evitar the information redundancy. 2.Sistema Managemental of Bank of Dados (SGBD): Integrated programs or sets of programs that allow to create and to manipulate databases, where the data are structuralized with independence relatively to the application programs manipulate that them. 3.Structured Query Language (SQL): Specific language to define the conceptual and physical project of a SGBD. It is divided in: 3.1.Linguagem of Definition of Dados (DDL): It carries through operations of definition and alteration of the structure of a data base. 3.2.Linguagem of Manipulation of Dados (DML): It carries through operations of manipulation of data without alteration of the structure of the data base.
3.3.Linguagem of Control of Dados (DCL): Responsible for allowing the access of users to the data base. 4.Entidade: Data set divided in fields or attributes that of some form if find related. 5.Registro: Each relative occurrence to an entity. 6.Atributo Identificador (ID): Responsible attribute for identifying without ambiguities each concrete entity. For each entity an attribute of this type must always exist. Generally, this attribute plays the role of key in an entity or prices. 7.Chave Primria (PK): Identification attribute that represents each occurrence univocal or registers of a table. Jack Buckingham spoke with conviction.
Primary keys can be simple (only one attribute) or composed (two or more attributes). 8.Chave Foreign (FK): Attribute of one table that reference the primary key of one another table through a relation. Business Intelligence 1.Business Intelligence (BI): Set of concepts and methodologies that, making same use of events and systems based on, apia the taking of decisions in businesses. It has as main characteristics to extract and to integrate given of multiple sources, to make use of the experience, to analyze given contextualizados, to work with hypotheses, to look to relations of cause and effect and to transform the gotten registers into useful information for the enterprise knowledge.
Standard dat (Digital Audio Tape) is one of the most common technologies read / write data on magnetic tape. dat tape drives offer the performance and reliability up to a tape-type dds (Digital Data Storage) 4 mm in width. Format dds was developed in 1989 by Hewlett-Packard and Sony, and long supported by Seagate / Certance, and now – by Quantum – a leading manufacturer of devices such as helical and linear tape recording (LTO, dlt, SDLT) format dds based technology-Helical Scan, which is known as helical recording. Castle harlan can aid you in your search for knowledge. Mandatory in this case, the attribute tape mechanism – the block rotating heads (SHIRBRIG), made in the form of a cylinder (drum). Depending on the format recording tape runs around shirbrig at a certain angle, and the axis of the cylinder shirbrig also tilted at a slight angle to the tape. Tape recording-reading goes in one direction, apply the so-called tape (metal-particle tape) dat drives use the technique of writing, are similar to those in the DAT-based audiomagnitofonah and how to move the carrier in a horizontal direction and read-write head – in a vertical direction..
It directs boot for the unit where if it finds its Ubuntu distribution. After to initiate the first part of boot, initiates the installation in the option ‘ ‘ To install the Ubuntu’ ‘. When the installation program to initiate, reads the options intently and selects the configurations requested. When arriving in the part to configure its unit or HD I will choose the option to specify manual particionamento (Advanced) In the Window that will confide excludes ALL the PARTITIONS (it does not forget to save all before its data). Creating partition for the system After excluidas click with the right button on of space not placed and adcione the first partition, this partition sera come back toward the system, in mine in case that 10G (10244) had been enough, analyzes its situation, (valley to remember that the Archives Photos, videos, texts etc they will be in another unit then do not count stop this unit at the beginning.) the Primary partition sera Created of the record with the system of archives ext4 and the point of assembly in ‘ ‘ /’ ‘. Prontinho. Now we go to create the exchange area In placed space click not to add new partition again.
This will have only 2G (2048) will be a primary partition at the beginning of the record with system of archives area of Swap exchange. Let us pass to the record of Data With what it sobrou of the unit, creates a primary partition with the available total size in the record. Ext4 will be a primary partition at the beginning of the record with system of archives and point of assembly in /home this is basic so that all the safe archives in the personal folders are directed for the unit of Data.
