    In this series of articles, I will present an application to manage a chess match database, ChesPosDb. It is not a program that plays chess; it only stores matches, but it allows queries with a large number of options: searching for games in which a series of moves occur, either one after another or separated by several moves, and even look for partially defined positions, no matter in which place on the board the pieces are located.

    WCF (Windows Communication Foundation) is a framework for creating distributed applications whose components communicate with each other through services, using a wide range of network protocols. In this article I will comment on the fundamentals of creating and configuring one of these services through a data connector for the DBTextFinder application, a program to search for texts in a database that can be extended to connect to any data management system.

    All major database servers allow the creation of executable objects, such as functions or stored procedures, using some type of SQL extension language, such as PLSQL in Oracle or T-SQL in SQL Server, so that we can create applications to access and manipulate data in a more sophisticated way. In this article I will show how we can access the source code of these objects from any program using the catalog views of three of the most popular RDBMS, MySQL, Oracle and SQL Server.

    The catalog views contain all the information concerning the structure of the database: schemas, tables, table fields, data types of the fields, integrity constraints, stored procedures code, etc. The knowing of them is essential to develop tools for data management independent of the structure. In this article we will view an example of one of these tools, DBTextFinder, a simple application that will allow us to search for text in the records of our database and within the code of the views and stored procedures.

    In this post we will look at the data structures and the necessary interfaces to develop connectors for any database to add to the DBTextFinder application, a tool for finding text in registers, stored procedures and views. You can also download sample code, developed with Microsoft Visual Studio 2013 with connectors for SQL Server, Oracle 12c and MySQL.
