Managing Databases And Their Categories Upravljanje zbirk podatkov in njihovimi kategorijami
Data bases are used in all kinds of businesses and it is important that they are kept running as efficiently as possible. Bazah podatkov se uporabljajo v vseh vrstah podjetij in pomembno je, da se redno prikazujejo čim bolj učinkovito. That is where data base management comes into play. To je, če baza podatkov za upravljanje začne igrati. Many data base managing systems, which are software that aid in organizing, obtaining information from and putting data into data bases, are designed to work with specific data base models. Veliko podatkov, baza upravljanje sistemov, ki so programsko opremo, da je pomoč pri organiziranju, pridobivanje informacij od in dajanje podatkov v bazah podatkov, so namenjene za delo s posebno podatkovno bazo modelov. A well-built database management system (DBMS) can be used for almost all of a company's database information. A dobro zgrajen sistem upravljanja baze podatkov (dbms) se lahko uporablja za skoraj vse družbe baza podatkov informacij. They can run on personal computers, for personal uses, or on giant mainframes that control all of a company's database. Lahko potekajo na osebnih računalnikih, za osebno uporabo, ali za mainframes velikan, ki nadzorujejo vse družbe baze podatkov. There are many types of data base management systems and most places with computers will use some form of one. Obstaja več vrst sistemov za upravljanje baze podatkov in večina krajev z računalniki bodo uporabljali določeno obliko ene. Example database management software includes computerized library systems, flight reservation systems, and computerized inventory systems. Primer upravljanje baz podatkov vključuje računalniško programsko knjižnico sistemi, letalske sisteme rezervacij, prevoznine in računalniških sistemov popisa sredstev. Even an email client's address book is a type of database management system. Tudi e-poštnega odjemalca adresar je vrsta sistema za upravljanje podatkovne zbirke. Basically a data base will store information in a series of columns and rows known as a table. V osnovi je baza podatkov se bo shranjevanje podatkov v seriji stolpce in vrstice, znano kot tabelo. When a particular piece of data needs to be retrieved, the data base system will use pointers to find that piece of data and bring it forward to be used. Če določen del podatkov, je treba Vzpostavljeno, je baza podatkov bo sistem uporabe kazalca, da bi našli, da del podatkov in ga posreduje naprej uporabljajo. There are many applications for database management systems, including accounting work, engineering work, and bibliographic work. Obstaja veliko vlog za upravljanje podatkovnih sistemov, vključno z računovodsko delo, inženirskem delu, in bibliografske dela. A data base management system can be used with several different categories of databases, based on how the data is stored. The six major categories of databases are the following: Vmesnik za podatkovno bazo sistema za upravljanje se lahko uporablja za več različnih vrst podatkovnih baz, ki temeljijo na tem, kako so podatki shranjeni. V šestih glavnih kategorij zbirk podatkov so naslednje: - Flat model Stanovanje model
- Hierarchical model Hierarhični model
- Network model Network model
- Relational model Relacijski model
- Dimensional model Dimenzijski model
- Object database model Object Model baze podatkov
The flat model is the simply category and is essentially a table or a matrix for data. The hierarchical model organizes data into a tree-like structure and allows a 1:N relationship between types of data. Stanovanje model je preprosto kategorije in je v bistvu tabela ali matrika podatkov. Hierarhično model organizira podatke v drevesu podobni strukturi in omogoča 1: N razmerje med vrstami podatkov. The network model is similar to the hierarchical model, only it is capable of larger relationships between types of data and allowing pointers to flow between data more efficiently based upon these relationships. Mreža je podoben model na hierarhični model, le da je sposoben večjega razmerja med tipi podatkov in nasvetov, da omogočajo pretok podatkov med učinkoviteje na osnovi teh razmerij. The relational model uses relations, attributes, and domains to organize data based on multiple tables. The dimensional model is a mixture of several types of database categories. Relacijski model se uporablja odnosi, lastnosti in področja za organiziranje podatkov temelji na več tabelah. Dimenzijske model je mešanica več vrst iz podatkovne zbirke kategorij. It primarily uses a table format that is described using dimensions, but it also follows a hiearchical structure. To v prvi vrsti uporablja obliki preglednice, ki je opisana z uporabo dimenzije, ampak tudi sledi hiearchical strukturo. Finally the object database model uses object-oriented programming techniques to store and manipulate data. It is becoming one of the most popular types of databases used and it helps bring database applications and programming applications closer together. Nazadnje je namen podatkovne zbirke model uporablja objektno programiranje tehnik za shranjevanje in manipulirati podatkov. To je postal ena najbolj priljubljenih vrst iz podatkovne baze in pomaga pri ustvarjanju baze podatkov in programskih aplikacij bližje skupaj. A company should not just stick with one database model, however. Using multiple models for different types of data is a great way to keep things organized and easy to access. Podjetje mora ne samo z eno palico model baze podatkov, pa. Uporaba več modelov za različne vrste podatkov, je odličen način, da se stvari organizirane in enostaven dostop.
