EMBEDDED DATA MANIPULATION LANGUAGE


Have you ever wanted to combine the freedom of your preferred programming language with the strength of SQL in a seamless way? Well, stop worrying! That's exactly what Embedded Data Manipulation Language (EDML) gives you. 



EDML: What is it?

Consider yourself writing a C++ code and having to update a database. Previously, you would develop two different programs: one for the SQL query and another for the C++ logic. This barrier is broken down by EDML. With it, you may include SQL statements straight into your C++ code. This produces a potent combination that lets you take advantage of your host language's processing capability while manipulating data with SQL's advantages.



How Does It Operate?

EDML is not a language that stands alone. This method incorporates SQL into an already-existing programming language, sometimes referred to as the host language. Here's a simplified breakdown:

1. Embed SQL Statements: Write your SQL queries right into the code of your host language by embedding them. These might be simple commands like UPDATE or SELECT statements.

2. Preprocessing: A preprocessor then enters center stage. The embedded SQL statements are recognized and kept separate from the host language code.

3. Translation: Preprocessors translate SQL statements into calls to the libraries of database management systems (DBMS). These libraries have an understanding with how to communicate with the particular database you are using.

4. Compilation Integration: Your host language code and the preprocessed code—which now includes calls to the DBMS libraries—are then compiled together.

5. Database: When you run the final program, the DBMS libraries take over for the embedded SQL statements. They execute the queries on the database and return the results back to your program.


EDML: Advantages
  • Conciseness: EDML maintains the order and cleanliness of your code. No more switching between different apps to interface with databases.
  • Efficiency: EDML may simplify your development process by integrating the best features of two languages.
  • Maintainability: Because the database logic is clearly segregated inside the program itself, EDML code may be simpler to maintain.


Is EDML the right tool for you?

For developers who often work with databases from within their applications, EDML is a useful tool. When managing data in languages such as C, C++, COBOL, or Fortran, EDML may be a game-changer.

Take Control: Interactive Data Manipulation Language

Image
Many applications rely heavily on data, therefore handling it well is essential. With the help of Interactive Data Manipulation Language (IDML), you may work directly with your data, changing and retrieving information in real-time.  What is IDML? Interactive Data Manipulation Language. Imagine a world in which you could communicate directly with your database, instantly adding, removing, and changing information . That is the elegance of IDML. IDML enables an interactive experience in contrast to conventional programming languages that need for writing and compiling codes. Here's an overview of IDML's capabilities: First  thing first is that  C(reate) R(ead) U(pdate) D(elete) Operations Made Easy with IDML,  via an intuitive interface, you may add new records (tuples) to a database relation, retrieve current data, change certain fields within a record, or even remove unneeded entries. Secondly,  Real-time Interactive Exploration with IDML is possible, it let...

The Blueprint: Data Definition Language

Image
Any application is built on data, however how can one specify the structure and organization of that data? Introducing the architect of your database, Data Definition Language (DDL).  What is DDL? Consider DDL to be the language that your database's underlying structure was created in. It lets you specify the tables, the columns inside those tables, and the data kinds that each column may hold—the fundamental components of your data. Consider a DDL statement to be a brick; with these "bricks," you build the whole structure for your data storage. DDL enables you to carry out the following important tasks, including: Table Creation: You name the table, designate the columns (fields) it will have, and list the data types that each column may carry. Data Typing: DDL defines data types like integer, text, and date, therefore guaranteeing data integrity. This specifies the format of the data each column can hold, preventing inconsistencies. Adding Constraints: DDL gives yo...
