Developing/coding/modeling anything while satisfying any specific standards will usually decrease the technical performance (efficiency) of your end product (software). Standards (like UML standards) are there to make creating the end product a more rapid process, and to make it more manageable to work with other people / reuse existing software. A 'capable programmer/developer' can almost always create end products that perform better by explicitly creating the program for its purpose, disregarding standard routines.
However, you almost always DO want to follow standards (not just UML), because the performance loss is negligible for most products.

In general, the differences are that interface has(1) no fields and(2) no implementation of methodsbut in UML interface may have features (fields), so the difference left is that interface in UML has no implemented methods while abstract class by definition is partially implemented class.

OverviewThe Unified Modeling Language (UML) is used to specify, visualise, modify, construct and document the artifacts of an object-oriented software intensive system under development.[1] UML offers a standard way to visualize a system's architectural blueprints, including elements such as:actorsbusiness processes(logical) componentsactivitiesprogramming language statementsdatabase schemas, andreusable software components.[2]UML combines best techniques from data modeling (entity relationship diagrams), business modeling (work flows), object modeling, and component modeling. It can be used with all processes, throughout the software development life cycle, and across different implementation technologies.[3] UML has synthesized the notations of the Booch method, the Object-modeling technique (OMT) and Object-oriented software engineering (OOSE) by fusing them into a single, common and widely usable modeling language. UML aims to be a standard modeling language which can model concurrent and distributed systems. UML is a de facto industry standard, and is evolving under the auspices of the Object Management Group (OMG). OMG initially called for information on object-oriented methodologies that might create a rigorous software modeling language. Many industry leaders have responded in earnest to help create the UML standard.[1]UML models may be automatically transformed to other representations (e.g. Java) by means of QVT-like transformation languages, supported by the OMG. UML is extensible, offering the following mechanisms for customization: profiles and stereotype. The semantics of extension by profiles have been improved with the UML 2.0 major revision.
UML has high learning curve.
The advantages of UML includes the ability to be used to model most types of applications and also generate test scripts apart from stub code. The biggest disadvantage of UML, is that it does not define a standard file format, which places limitations on the software capabilities.
The latest version of UML is UML 2.4 (beta), released in January 2011.

what is the difference between ERD and UML Flowcharts.
UML is visual language - various rectangles, ovals, lines, arrows, etc. each having special meaning and used to draw different diagrams.Microsof Visio is software product that you can purchase to draw UML diagrams on your computer. There are many other UML tools that you can get even for free to draw UML diagrams. Or you can draw UML diagrams with a pencil on a piece of paper.
See examples of different types of UML diagrams, select which diagrams you need, find a tool to draw UML diagrams.
OMT is a modelling technique and UML is a Modelling language. OMT stands for object modelling technique and is given by Jim Rambaugh . UML is unified Modelling language and has a layered architecture.

UML 2.4 has 14 different types of diagrams, so you will need to draw not one diagram but several of those. See provided link for online shopping UML examples which provides examples of several common types of UML diagrams.
