'''Component-based Scalable Logical Architecture (CSLA)''' is a [[software framework]] created by [[Rockford Lhotka]] that provides a standard way to create robust [[object oriented]] programs using [[Business object (computer science)|business object]]s. Business objects are objects that abstract business entities in an object oriented program. These entities could be things such as sales orders, employees, or invoices, and so on. CSLA was originally targeted toward [[Visual Basic]] 6 in the book ''Visual Basic 6.0 Business Objects'' by Lhotka ISBN 1-86100-107-X. With the advent of [[.NET Framework|Microsoft .NET]], CSLA was rewritten with no code carried forward and called CSLA.NET. This revision took advantage of [[Web Services]] and the fully object oriented languages that came with Microsoft .NET(i.e. [[Visual Basic|Visual Basic.NET]] and [[C Sharp programming language|C#]]). CSLA.NET was expounded in ''Expert C# Business Objects'' ISBN 1-59059-344-8 and ''Expert One-on-One Visual Basic .NET Business Objects'' ISBN 1-59059-145-3, both written by Lhotka. Though CSLA and CSLA.NET were originally targeted toward [[Microsoft]] [[programming languages]], most of the framework can be applied to most object oriented languages.
