What is Data Layer ?

The term "data layer" generally refers to a conceptual or physical layer within a software architecture where data is managed, processed, and stored. It serves as an intermediary between the user interface and the backend systems, providing a structured way to handle data throughout an application or system.

Here are a few key aspects of a data layer:

Data Management: It encompasses how data is organized, stored, retrieved, and manipulated within an application or system. This could involve databases, data warehouses, or other storage solutions.

Abstraction: The data layer often abstracts the underlying complexity of data storage and retrieval from the rest of the application. This allows developers to work with data in a consistent and manageable way.

Integration: It facilitates integration with other systems or services. For example, a data layer might provide APIs or interfaces for other parts of the application to interact with the data.

Data Access Logic: Includes the logic and rules for accessing and modifying data. This might involve querying databases, performing validations, applying business rules, and ensuring data integrity.

Scalability and Performance: A well-designed data layer considers scalability and performance requirements. It may involve techniques like caching, indexing, or partitioning to optimize data access and storage.

Security: Ensures that data is stored securely and access controls are enforced. This might involve encryption, authentication mechanisms, and adherence to data protection regulations.

In summary, the data layer is a critical component of software architecture that manages data throughout its lifecycle within an application, ensuring reliability, efficiency, and security in handling data operations.

OOP JavaScript : Classes are not classes in JavaScript 👩‍💻👴🏻👴🏻. Let's take a look what exactly classes are in Javascript now that up to this 7th slides set agree that Javascript is a prototype based Object Oriented Programming language. Yes,they are not classes,but functions behind the scene.They are classes and work classically on the surface. Let's dive in at take a look. #javascripttricks #javascriptobjects #classexpressions #constructorfunctions #objectorientedprogramming #prototypes #prototypeinheritance (at Lilongwe, Malawi) https://www.instagram.com/p/CCJYdaIBoDr/?igshid=4avmysv51v7s

JavaScript ES6 syntax part 2. This is the second part of our es6 syntax in our Javascript Quick guide series.It is a continuation of where we left in part 10 of this slides tutorial sets. In this post we discuss the new class feature added in Javascript in ES6.The classes make development of applications in much better way without touching the bare bones of prototype inheritance.Yes,it's a syntactic sugar over the prototype,but we really don't get caught up in the work around to implement OOP features by using the prototype.You actually work the way you do in Java with afew exceptions,but the syntax is almost similar now with the block level scope introduced through let and const variable declarations. This part touches afew areas on classes.

Understanding JavaScript Objects. This is part 8 of our continued Quick guide to JavaScript.In this part we are going to look at the most fundamental part of JavaScript, Objects. As we know, everything in Javascript is an object.That include strings, numbers,Booleans,arrays,sets, functions and more.At the center of Objects lays properties and methods. If you can understand how Objects work,then you will have covered almost half of what there is to learning JavaScript. I must state that this is the first part on Objects though.

Tricks for Quickly understanding JavaScript concepts. I learnt and grasped the ins-and-outs of python in about 2 months 😎😎😀. For JavaScript,it was a completely different story 🤣🤣. You think you understand it now until stuff like hoisting, lexical environment,closures,callbacks,IIFE,then data structures pop-in. Then, you are like what@#$.Then you are forced to either give up or copy smart coders' code as you go until you find peace with it all. But hey,my trick was to learn JAVA😙.Ahhnha! Yes,not javascript,Java.I got a few ideas,then developed some tricks of my own after a long list of reads from a bunch of 200s,if not a thousand paged book volumes on javascript coupled with YouTube tutorials...bakey... the new Boston...w3schools... In this short slides tutorial,I show you one of the many tricks to avoid going that lane.
