 My table is using graph theory. Let's look at the action, notification, and remove of features in all versions of the database office. For my, I'm a coach and model from Japan. I have a new project in graph database. Given the graph database, please raise your hand. Oh, thank you. I have a new paper for the base and the graph weekend AP, new speaker and manager. And I have a highland legal list, Japanese legal scheme, and coffee. Okay. And agenda in space agenda, graph theory, and the second three graph is graph is one is timeline, second is mathematical functions, third are functions. In this presentation, I don't know if they have been reused. My version gives me do you have any of these questions? I did the version written for UI or local forms. And that is one of my favorite questions. When it is formed, version of it in the language or when has it written a form for functions and Excel versus functions. Okay. Let's talk about graph theory. Okay, graph is equal relationship and nodes. Just three components. Relationship is a circle. Okay, here you can see. And nodes, the circle rate for that graph. And this graph is graph is Java 17. This is the 17th or 17th level. So this function is here. You see the graph rate function. It is easy to find the modification function. I use the tools at this time. They were at this point 4.1 and there was much graph database. Graph database however in any graph database. So I use this time near HA 4.11. So you can use other graph database. I like it. This is the famous timeline of the offices. Okay, let's start with star office. I choose some data from star office and their office. This is a simple data of timeline. Okay, star office forward. And sometimes for star office and their natural office 4.1, I want to forward to 4.1. And they know this 3.3.3 to 7.4. And star office is here. This is the data. So you put the data to star office with a base. This is a graph. Each product is separate at this time. So I have the timeline to work relationship. Star office 5.2.2 for office or 6.3.3 to 4.1.4 for graph data. I have the relationship. So you can see a graph here. This is a from office 1 to regular office vision. And this line is a regular office. The red line to blue is a virtual office. Easy to understand. And 4.1.4 for 4.1.4 for 4.1.4 for 4.1.4 for 4.1.4. And this is Excel and the later functions. I compared the functions. Just about 50 functions from A to D. This is a data of web. Excel. Like this. It's not good for this data. Something this web state Excel 407. This is a step. This is a digital function or something like this. It's easy to read for humans, but it's just good computer. I get the data from here. Let it change the data here. This is a function name. A, B, S function or A, C, C are in function. And version. From Excel 2013. What type? Time is here. And description is here. This is Excel data. Some Excel functions name is a little bit changed. B, E, T, A this function. New one is dot. Dot this function from Excel. Okay. Next. I get the data from a database. This is from a database. This is a function name, A, B, S. This description returns some data. This is a data of the label is here. Function name, version type or type description. This is Excel graph is here. This is a label of the graph here. So this is a label of the last graph is here. Green one is the database function is here. Function name, A, A, B. Okay. And orange is Excel function. Excel function is a formal function. You see a formal. This is here. 60. 46 same functions but four different functions. It's easy to find the function. And next. Readies note. Readies note pages here. Readies note is a lot of language in the Japanese or something like that. And readies note a lot of versions from 3 to 7. Label 3 and 3.4. 2.5, 2.6 and label 7 7.4, 2, 7.5 Okay. And the 7.4 has many languages but a lot of languages. Okay. This time is focused on font and language. In which version did the font, languages change? No problem for green one. So I need for this the font readies note from where additional information adds okay. This is a font functions graph is here. Green one is label 6.4 font category or category is here middle of the ground one and the middle is red. This font open sends something and add 3 fonts here. Not the fonts and yellow fonts and red fonts. Next I have to try I hope to report all readies note from where used with yellow tools like a batch of or something like that and all languages or the readies note I hope to report all languages and all readies note to the one into the background and compare all readies and or multiply really first presentation and
