Parser Generator

If you have a need for a parser generator for your applications say a SQL parser or an expression parser to plugin somewhere in your application, your obvious choices are ANTLR or JavaCC.

ANTLR (ANother Tool for Language Recognition) is a parser generator developed by Terence Parr, it is extremely versatile and is capable of generating parsers in multiple programming languages, but requires a run time library. The Definitive ANTLR 4 Reference is an excellent book to get into ANTLR.

 JavaCC (Java Compiler Compiler) was written originally by Dr. Sriram Sankar and Sreenivasa Viswanadha. It is only capable of generating parsers in Java but doesn’t require a runtime library and the parsers it generates are very performant for an LL(k) parsers.

Information Governance vs Data Governance

Information Governance vs. Data Governance: Key Differences While Information Governance (IG) and Data Governance (DG) are closely related, they focus on different aspects of managing organizational assets. Here’s a simple breakdown of their differences and how they work together: 1. Definitions Data Governance (DG): - Focuses on managing **data as an asset**. - Ensures data is accurate, consistent, secure, and available for use. - Example: Defining who can access customer data and how it’s stored. Information Governance (IG): - Broader than DG, focusing on managing **all forms of information** (structured data, unstructured data, documents, emails, etc.). - Ensures information is used effectively, ethically, and in compliance with regulations. - Example: Setting policies for retaining and disposing of emails and documents. 2. Scope Data Governance: - Primarily deals with **structured data** (e.g., databases, spreadsheets). - Focuses on...

Defensible Disposition - Purge; Don't splurge in legal costs!

Defensible Disposition: A Smart Strategy for Compliance and Security What Is Defensible Disposition? Defensible disposition is the legally sound, systematic process of discarding or destroying records, documents, and data that are no longer needed for business, legal, or regulatory reasons. By implementing this practice, organizations ensure compliance with legal requirements while reducing risks associated with unnecessary data retention. Why It Matters: Key Principles ✅ Compliance: Aligns with laws, regulations, and industry standards to avoid legal and financial penalties. ✅ Accountability: Establishes a clear audit trail to document every step of the disposition process. ✅ Security: Protects sensitive information by ensuring secure destruction, preventing unauthorized access or breaches. ✅ Efficiency: Eliminates outdated records promptly, reducing storage costs and streamlining data management. How to Implement Defensible Disposition 1️⃣ Identify Records – Determine which reco...
