Selection of the right kind of components having potential for reuse is important.Domainanalysisisa promisingtechniquewhich can beusedtocreatereusablecomponents. ComponentindexingandstoringIndexingrequiresclassificationofthereusablecomponents so that they can be easily searched when looking for a component for reuse. Thecomponents need to be stored in a Relational Database Management System (RDBMS) or anObjectOrientedDatabaseSystem(ODBMS)forefficientaccesswhenthenumberofcompon entsbecomes large. Component searching- The programmers needto searchfor right components matchingtheir requirements in a database of components. To be able to search components efficiently,the programmers require a proper method to describe the components that they are lookingfor. Component understanding- The programmers need a precise and sufficiently completeunderstanding of what the component does to be able to decide whether they can reuse thecomponent. To facilitate understanding, the components should be well documented andshould dosomethingsimple.
