Managing Databases And Their Categories Ġestjoni Databases And tagħhom Kategoriji
Data bases are used in all kinds of businesses and it is important that they are kept running as efficiently as possible. Data bases jintużaw f'kull tip ta 'negozji u huwa importanti li dawn jinżammu running-aktar mod effiċjenti possibbli. That is where data base management comes into play. Dan huwa fejn data base ġestjoni jidħol. 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. Ħafna data base tmexxija ta 'sistemi, li huma softwer li l-għajnuna fl-organizzazzjoni, mill-kisba ta' informazzjoni u tqegħid fis data data bases, huma ddisinjati biex jaħdmu ma 'data base mudelli speċifiċi. A well-built database management system (DBMS) can be used for almost all of a company's database information. Mibnija sew A database management system (DBMS) tista 'tintuża għal kważi kollha ta' kumpannija-database ta 'informazzjoni. They can run on personal computers, for personal uses, or on giant mainframes that control all of a company's database. Huma jistgħu jaħdmu fuq kompjuters personali, għall-użu personali, jew fuq giant mainframes li kollha ta 'kontroll tal-kumpannija database. There are many types of data base management systems and most places with computers will use some form of one. Hemm ħafna tipi ta 'data base' sistemi ta 'ġestjoni u l-aktar postijiet ma' kompjuters se tuża xi forma ta 'wieħed. Example database management software includes computerized library systems, flight reservation systems, and computerized inventory systems. Eżempju ġestjoni software tinkludi database kompjuterizzata librerija sistemi, sistemi ta 'prenotazzjoni tat-titjira, u sistemi kompjuterizzati inventarju. Even an email client's address book is a type of database management system. Anke email client-indirizz tal-ktieb huwa tip ta 'database management system. Basically a data base will store information in a series of columns and rows known as a table. Bażikament a data base se jaħżnu informazzjoni f'serje ta 'kolonni u ringieli magħrufa bħala tabella. 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. Meta partikolari biċċa tad-data jeħtieġ li tiġi rkuprata, id-data base sistema se użu pointers biex issib dik il-biċċa tad-data u jġibu 'l quddiem li għandhom jintużaw. There are many applications for database management systems, including accounting work, engineering work, and bibliographic work. Hemm ħafna applikazzjonijiet għal database sistemi ta 'ġestjoni, inklużi l-kontijiet xogħol, l-inġinerija xogħol, u biografika xogħol. 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: A data base sistema ta 'ġestjoni tista' tintuża ma 'diversi kategoriji differenti ta' databases, ibbażata fuq kif id-data hija maħżuna. Is-sitt kategoriji kbar ta 'databases huma dawn li ġejjin: - Flat model Flat mudell
- Hierarchical model Ġerarkika mudell
- Network model Network mudell
- Relational model Relazzjonali mudell
- Dimensional model Mudell tridimensjonali
- Object database model Object database mudell
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. Il-flat il-mudell huwa sempliċiment kategorija u hija essenzjalment 'tabella jew matriċi għall data. Il-mudell ġerarkiku jorganizza data fis siġra struttura simili u jippermetti a 1: N relazzjoni bejn tipi ta' data. 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. Il-mudell ta 'netwerk huwa simili għall-mudell ġerarkiku, biss hija kapaċi akbar relazzjonijiet bejn tipi ta' data u li jippermettu pointers għal fluss bejn id-data b'mod aktar effiċjenti bbażati fuq dawn ir-relazzjonijiet. 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. Il-mudell juża relazzjonali relations, attributi, u l-oqsma biex jorganizza data bbażata fuq multipli tabelli. Dimensjonali Il-mudell huwa taħlita ta 'diversi tipi ta' database kategoriji. It primarily uses a table format that is described using dimensions, but it also follows a hiearchical structure. Huwa primarjament użi tabella format li huwa deskritt bl-użu dimensjonijiet, imma jirriżulta wkoll a hiearchical istruttura. 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. Finalment l-oġġett database mudell juża oġġett orjentati lejn il-programmazzjoni tekniki li jaħżen u timmanipula data. Qed issir waħda mill-aktar popolari tipi ta 'databases użati u jgħin database idaħħlu applikazzjonijiet u programmazzjoni applikazzjonijiet eqreb flimkien. 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. A kumpannija għandha mhux biss stick b'wieħed database mudell, madankollu. Uża multipli mudelli għal tipi differenti ta 'data huwa mod tajjeb ħafna biex iżommu affarijiet organizzati u faċli biex taċċessaha.
