Database software

Du får en grundig introduktion til både Access 2016 og databaser generelt. Du lærer at bygge din egen database helt fra bunden. Du lærer selve kernen i databaser: at lave relationer i databasen, så du kan koble forskellige tabeller i databasen sammen. Du lærer også teorien bag, så du undgår databasens mange faldgruber. Du lærer at oprette indtastningsformularer, at importere data fra f.eks. txt- og csv-filer og Excel-dokumenter, og du lærer at danne avancerede rapporter med mulighed for at lave sum- og andre beregninger.For at komme godt i gang med Access, introducerer vi i starten af hæftet grundbegreber inden for databaser, ligesom vi gennemgår "normalisering", som er den proces, du skal igennem, for at transformere rådata eller ustrukturerede data til at være data i en form, som egner sig til en database.Access 2016 er Microsofts databaseprogram, og programmet retter sig mod brugere, der har behov for en mindre til mellemstor database med op til 100.000 poster.

Dette hæfte giver en hurtig og letlæst introduktion til SQL.SQL anvendes til at håndtere data og du vil lære at hente, sortere og filtrere data, oprette beregninger, gruppere data, samt kombinere data fra forskellige tabeller. Når du har læst hæftet vil du også kunne indsætte, opdatere og slette data.Hæftet er rettet mod dig som på en hurtig og nem måde vil lære SQL og ønsker at kunne anvende det i dagligdagen til løsning af database relaterede opgaver. Hvis du har egen virksomhed kan SQL bl.a. bruges til at holde styr på dine kunders ordrer eller dit lager.Hæftet er primært rettet mod brugere af Microsoft SQL Server, men en stor del af indholdet kan også anvendes på andre databaseplatforme som f.eks. ORACLE.
