LANGUAGE INTEGRATED QUERY (LINQ) PERFORMANCE EVALUATION

Tematika diplomske naloge zajema predstavitev jezikovno integriranih povpraševanj(LINQ) LINQ predstavlja združen dostop do različnih zbirk podatkov. To pomeni, da do vseh zbirk dostopamo na skoraj identičen način, s čimer se ne rabimo obremenjevati z načinom dostopa in s sintakso brskanja po različnih zbirkah. Če poznamo en jezik, poznamo vse. LINQ je iniciativa podjetja Microsoft, ki ga je integriral v svoje orodje Visual Studio in je na voljo z verzijo C# 3.0 in naprej. Jedro LINQ predstavljajo metode, ki so implementirane v .NET ogrodju. Pri tem se postavlja vprašanje hitrosti in zmogljivosti izvajanja v nasprotju s klasičnim dostopom do podatkov. V diplomskem delu bomo predstavili nekaj pristopov, s katerimi lahko hitrost izvajanja poizvedb LINQ z malo truda bistveno izboljšamo. Poznamo različne tipe LINQ in najpogosteje uporabljene bomo tudi predstavili.Subject of this work covers presentation of the Language Integrated Query (LINQ). LINQ represents united access to different databases. This means that all databases are accessed in almost identical manner and we don\u27t need concern ourself anymore with different ways to access and browsing syntax of each database. If we master one language we master them all. LINQ is initiative of Microsoft, which is integrated in .NET framework and is available from C# 3.0 version onwards. The core of LINQ are methods implemented in .NET framework. Of course, this raises the question of performance in comparison with conventional access to databases. In that matter we will present a few tricks that can be with little effort usefull for significant improvement of LINQ queries performance. There are different types of LINQ and most commonly used will be presented
