Visual FoxPro 9.0 is a great tool for building database solutions of all sizes. Its data-centric, object-oriented language offers developers a robust set of tools for building database applications for the desktop, client-server environments, or the Web. Developers will have the necessary tools to manage data—from organizing tables of information, running queries, and creating an integrated relational database management system (DBMS) to programming a fully-developed data management application for end users.
- Data-Handling and Interoperability. Create .NET compatible solutions with hierarchical XML and XML Web services. Exchange data with SQL Server through enhanced SQL language capabilities and newly supported data types.
- Extensible Developer Productivity Tools. Enhance your user interfaces with dockable user forms, auto-anchoring of controls, and improved image support. Personalize the Properties Window with your favorite properties, custom editors, fonts, and color settings.
- Flexibility to Build All Types of Database Solutions. Build and deploy stand-alone and remote applications for Windows based Tablet PCs. Create and access COM components and XML Web Services compatible with Microsoft .NET technology.
- Reporting System Features. Extensible new output architecture provides precision control of report data output and formatting. Design with multiple detail banding, text rotation, and report chaining. Output reports supported include in XML, HTML, image formats, and customizable multi-page print preview window. Backward compatible with existing Visual FoxPro reports.
Relational Database Management System(RDBMS)
The stored data is allowed to be manipulated using relational operators in Relational Database Management System. SQL is used as the data query language in this system.This article will give you complete information about Relational Database Management System like its advantages, uses, features, disadvantages and how it is different from DBMS.
Features of RDBMS
The system caters to a wide variety of applications and quite a few of its stand out features enable its worldwide use. The features include:
- First of all, its number one feature is the ability to store data in tables. The fact that the very storage of data is in a structured form can significantly reduce iteration time.
- Data persists in the form of rows and columns and allows for a facility primary key to define unique identification of rows.
- It creates indexes for quicker data retrieval.
- Allows for various types of data integrity like (i) Entity Integrity; wherein no duplicate rows in a table exist, (ii)Domain Integrity; that enforces valid entries for a given column by filtering the type, the format, or the wide use of values, (iii)Referential Integrity; which disables the deletion of rows that are in use by other records and (iv)User Defined Integrity;providing some specific business rules that do not fall into the above three.
- Also allows for the virtual table creation which provides a safe means to store and secure sensitive content.
- Common column implementation and also multi user accessibility is included in the RDBMS features.
