If I were to make an Arkham style game.

Probably a dlc, because idk if there's enough to have a full game.

General

K so Bruce is dead, the mantle of the bat is sort of being filled by Cassandra, dealing with the rogues gallery, and Red Hood deals in the miscellaneous threats like the street gangs. The other bats are still there in support rolls of course, babs as Oracle, tim investigating, ect....

Specific

Main bad guy: Deathstroke

Very simplified plot - Slade tries taking over Gotham using his mind control serum and Jason calls on an expert to help. Unfortunately, his friend and his sister don't exactly get along.

Playable characters: Cassandra as the Bat, Jason as Red Hood, and Rose Wilson.

Cassandra has access to most of Bruce's stuff and plays the closest to him, but her 'detective vision' has her reading her opponents body language instead of a scanner. She also utilizes swords and knives over batarangs. She moves through Gotham with a grapple and gliding wings. (Movement similar to Arkham Batman moving around Gotham)

Jason has his guns, he has to use ladders on buildings and has climbing shoes to scale. He can jump from building to building, but he is slower and much heavier than Cass. His visor shows him tactical information and weak points, also connects him to databases with information on whoever he is scanning. (Movement is of a heavy strong character, like wolverine in the wolverine origins game)

Rose of course uses her swords, which she can use to climb up and slide down buildings. Rose utilizes a lot of parkour to move. Her form of 'detective vision' is her using her precognition to see where enemies will be ahead of time, with phantom versions of them moving ahead of them. ( Movement is similar to the assassins creed series)

Basic idea for looks

I think Rose would incorporate more red and white than this, but this is the vibe.

But with this mask

Specifically so that Rose can tease him about Red Hood not actually wearing a red hood.

Each playable character can call in one of three options of other members of the family/friends to help in fights.

Jason: Dick, Kate, Harper

Cass: Duke, Tim, Steph

Rose: Eddie, Jericho, Damian

Today the interns brought me a webapp that they had built using django 5.0 because the build process keep failing when they tried deploying it to production. turns out only django 1.11 supports for our database (oracle 11g) and django LTS support ended 4 years ago for that version....

They were not happy when I told them the solution was to rewrite the entire thing.

DBMS vs RDBMS Which One Should You Learn for a Successful Database Career?

In the fast-evolving world of IT, databases are the backbone of every application. Whether it's managing customer information for an e-commerce platform or storing transaction details for a bank, databases are everywhere. If you’re aiming for a career in database management, you’ve likely encountered terms like DBMS and RDBMS. But what exactly are they, and which one should you focus on to build a successful career?

Understanding the difference between DBMS and RDBMS is crucial for making the right choice. While DBMS lays the foundation for database management, RDBMS takes it to the next level, handling complex relationships between data. If you’ve faced DBMS interview questions, you know the importance of grasping these concepts to excel in the job market.

In this blog, we’ll break down DBMS and RDBMS, explore their key features, and help you decide which technology aligns better with your career goals.

2. What is DBMS?

DBMS, or Database Management System, is a software tool that helps users store, retrieve, and manage data efficiently. It’s the most basic form of database technology, ideal for small-scale applications where data relationships are not complex.

Key Features of DBMS:

Data is stored in files or collections without enforcing strict relationships.

Limited support for data consistency and integrity.

Focuses on storing and retrieving data without advanced functionalities.

Examples of DBMS:

Microsoft Access.

XML Databases.

File-based systems.

Primary Use Cases: DBMS is perfect for small-scale systems like personal data management or lightweight applications with simple data requirements.

Imagine you’re managing a local library’s book inventory. A DBMS can store details like book titles, authors, and availability, but it doesn’t establish relationships between them, such as which books are loaned to which members.

While DBMS provides an excellent starting point for database management, its simplicity can become a limitation as your application scales or requires more complex data handling.

3. What is RDBMS?

RDBMS, or Relational Database Management System, is an advanced version of DBMS where data is stored in a tabular format with rows and columns. What sets RDBMS apart is its ability to enforce relationships between data, ensuring consistency and integrity.

Key Features of RDBMS:

Follows a structured approach using tables to store data.

Supports SQL (Structured Query Language) for querying and managing data.

Enforces data integrity through primary keys, foreign keys, and constraints.

Adheres to ACID properties (Atomicity, Consistency, Isolation, Durability) for reliable transactions.

Examples of RDBMS:

MySQL.

PostgreSQL.

Microsoft SQL Server.

Oracle Database.

Primary Use Cases: RDBMS is ideal for large-scale applications requiring complex data relationships, such as e-commerce systems, banking solutions, and healthcare databases.

Let’s revisit the library example, but this time with RDBMS. Using RDBMS, you can store books in one table, members in another, and use relationships to track which member has borrowed which book. This ensures data consistency, accuracy, and easier management as the library grows.

The Role of ETL Testing Automation in Enhancing Data Quality

ETL (Extract, Transform, Load) testing is a crucial process in ensuring the accuracy and reliability of data integration and migration projects. ETL testing tools play a vital role in this process by enabling organizations to verify the correctness of data transformation, data quality, and data integrity. With the increasing complexity of data integration projects, selecting the right ETL testing tool has become a daunting task. In this article, we will discuss the key features to look for in ETL testing tools to ensure that your organization ETL data quality the best tool for its needs.

Data Source Connectivity

One of the primary features to look for in an ETL testing tool is its ability to connect to various data sources. The tool should be able to connect to different types of databases, file systems, and cloud storage services. This includes support for popular databases such as Oracle, Microsoft SQL Server, MySQL, and PostgreSQL, as well as cloud-based services like Amazon S3 and Azure Blob Storage. The tool should also support various file formats such as CSV, JSON, and XML.

Data Transformation and Validation

Another key feature of an ETL testing tool is its ability to perform data transformation and validation. The tool should be able to validate data against predefined rules and constraints, such as checking for null values or invalid dates. It should also be able to perform complex transformations such as aggregations, filtering, and sorting. Additionally, the tool should support regular expressions (regex) for pattern matching and string manipulation.

Data Quality Checks

Data quality checks are essential in ensuring that the transformed data meets the required standards. An ETL testing tool should have built-in features for performing data quality checks such as checking for duplicate records, invalid values, and inconsistent formatting. The tool should also be able to generate reports on data quality issues and provide recommendations for improvement.

Test Automation

Test automation is critical in reducing manual effort and increasing efficiency in ETL testing. An ETL testing tool should have features that enable test automation such as scheduling tests to run at specific intervals or triggering tests based on events like changes in source or target systems.

Collaboration Features

ETL testing often involves collaboration among multiple teams including development teams responsible for creating source systems; IT teams responsible for managing infrastructure; business stakeholders who understand business requirements; etcetera - all these groups need access at some point during project execution phases so there needs some sort mechanism which allows them share information securely while working together towards common goal i.e., delivering high-quality integrated datasets which meet their intended use cases effectively!
