ESF Database Migration Toolkit vs. Luna Modeler vs. Unlambda vs. dbForge Data Compare for MySQL Comparison Chart

It dramatically cuts the effort, cost, and risk of migrating to/from any of the following database formats: Oracle, MySQL, MariaDB, SQL Server, PostgreSQL, IBM DB2, IBM Informix, InterSystems Caché, Teradata, Visual Foxpro, SQLite, FireBird, InterBase, Microsoft Access, Microsoft Excel, Paradox, Lotus, dBase, CSV/Text and transfer any ODBC DSN data source to them. This software can help you quickly migrate a variety of data, structures and objects, saving you a lot of time and money. It will automatically migrate all table structures, data, schemas(Oracle, SQL Server 2000 or higher, PostgreSQL, IBM DB2 and so), LOBs(Large Text/Binary Objects), primary/foreign keys, indexes, auto-increment(serial), comments and default values and more. You can migrate data between two different character sets(e.g.: UTF8, CP1250 etc.) and the software automatically convert different data encodings. You can also change the field name/data type/nullable/precision/numscale or filter data when migrating.

Unlambda is a programming language. Nothing remarkable there. The originality of Unlambda is that it stands as the unexpected intersection of two marginal families of languages. Functional programming languages, of which the canonical representative is Scheme (a Lisp dialect). This means that the basic object manipulated by the language (and indeed the only one as far as Unlambda is concerned) is the function. Rather, Unlambda uses a functional approach to programming: the only form of objects it manipulates are functions. Each function takes a function as an argument and returns a function. Apart from a binary “apply” operation, Unlambda provides several built-in functions (the most important ones being the K and S combinators). User-defined functions can be created, but not saved or named, because Unlambda does not have any variables.
