Best Tools for Data ModelingР В РІР‚СњР вЂ™Р’Вata modeling is the process of drawing a conceptual model of your physical database. LetР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s discuss the best database tools to use in the upcoming year for each stage of the development and maintenance process. Selecting the best toolkit is critical to success in 2022.

To simplify this complex process, every database professional must have a good set of tools.

This complicated process involves many professionals like database architects, software engineers, programmers, database administrators, and software testers, just to name a few. Different activities are included, such as modeling data, developing and managing physical databases, querying, programming, testing, performing administration functions, and making modifications, among others. Read on and letР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s get ready to take on the challenges in 2022.Р В РІР‚СњР вЂ™Р’В«uilding and maintaining a database is not a simple process it requires the right database tools. Time to get prepared for 2022! You should equip yourself with the best database tools so that you can outshine your competitors and delight your clients in the coming year.

Indeed, after filling some fields of our database, we decided to test all the statistic queries to see if they were functional.After this step, we also decided to create a user on the localhost who will be able to connect and have all privilegies on the database as expected in the subject.Another successful year is coming to an end.

Indeed, some of the SQL code functions are not available or not usually represented by geometric forms like on our algebraic trees which are the following:Р В РІР‚СњР В РІР‚РЋinally, we decided to make all the statistic queries that the travel agency whished. We also made the three algebraic trees as we couldbecause of the minimalism of this type of representation. In order to represent some queries of the statistic management, we decided to realize their algebraic trees. To be more precise, this SQL code will allow us to create all the tables and the attributes needed in our PDM in order to create the new database and apply some Query asked by the travel agency. Finally, we have our LDM/PDM, and the SQL code linked to the creation of the PDM.

Has no transitive functional dependenciesР В РІР‚СњР В РІР‚РЋollowing the creation of our Conceptual data model on JMERISE, we simply verified if it was correct by clicking the button on the software, and then we converted it into an LDM/PDM by clicking the button convert the CDM.

Each table cell should contain a single value.

Finally, we studied our CDM a long time to make it better and to apply the first three normal laws which are the following: Then, we added an ID for each table to make the CDM easier to manipulate, and we applied cardinalities according to the text provided which explained us the situation. When the data dictionary will be done, it will be easier to make the Conceptual data model (or CDM).Р В РІР‚СњР В РІР‚РЋor the realization of the conceptual data model, we first started making entities, attributes, and relations between the different tables by using JMERISE Software. In this one, we will have to class data by their code, designation, type of data, length, and notes. In order to class all the data provided in the data file of our school we decided to create a data dictionary.

These representations helped us organizing ourselves around the different tasks and steps of the project as you can see on the followings:

How to digitize and make accessible the travel agency's information system thanks to the data extracted from the 'raw' interviews? Logical & Physical Data Model (LDM/PDM)Р В РІР‚СњР В РІР‚С›t the beginning of the project, we made a representation of our organization about the different tasks of everyone by realizing an OBS (Organization Breakdown Structure) and WBS (Work Breakdown Structure). The client compartmentalizes its business processes into several categories, each with its own set of functionalities: This information was extracted from 'raw' interviews (without analysts' work) with our client's decision-makers. Introduction Context :Р В РІР‚СњР В РІР‚С› travel agency wishes to digitize its information system using the information it has. The subject of this project is Data Base and Data Modeling with SQL code on SQL workbench. It explains the fact I was in a project team of 3 classmates. This project is one I've done for my studies.
